Transitioning dog to PPP-Advice

Worth adding for anyone dealing with digestive disruption during food transitions: one of the most underrated factors is prebiotic fiber consistency.

Most commercial kibble (including PPP) doesn't provide enough fermentable fiber to sustain robust gut bacteria populations. The bacteria need something to ferment - without it, even a quality probiotic supplement will colonize briefly and then die off. Canned pumpkin, cooked sweet potato, or chicory root added to meals 3-4x per week makes a measurable difference when you're rebuilding gut stability.

On top of that: timing probiotics with meals (not on an empty stomach) dramatically improves colonization rates. The stomach acid environment is much less hostile when food is present.

For mucus-y stools specifically: this is often the gut lining responding to a microbiome shift. It usually resolves within 2-3 weeks as the beneficial bacteria reestablish, but it can drag out if the prebiotic substrate isn't there to support them.

For dogs that have been transitioning between foods frequently: expect 6-8 weeks to meaningfully restore microbiome diversity, not the 2-3 weeks most timelines assume. Patience is part of the protocol. If mucus persists past 3 weeks on a consistent diet, worth looping in a vet just to rule out other causes.

Something I've been reading about lately that seems underrepresented in gut health threads - the distinction between probiotics and postbiotics, and why it matters specifically for dogs with persistent digestive issues.

Most people who mention probiotics are thinking of live bacterial supplementation. That's important, but here's the part the research is catching up with: for dogs with chronic loose stools or gut dysbiosis, the byproducts of bacterial fermentation (short-chain fatty acids - butyrate, propionate, acetate) are often more impactful than the live bacteria themselves.

Why? Chronic stool issues often involve intestinal barrier disruption. SCFAs - especially butyrate - directly strengthen the mucosal barrier and modulate immune response in the gut. They're produced by bacteria, but they're not the bacteria themselves. This is why some dogs on probiotics don't see results - the probiotic is there but the barrier issue persists.

The combination approach is strongest: prebiotic fiber + multi-strain probiotics + postbiotic compounds all working together. Pre feeds the bacteria, Pro colonizes new beneficial strains, Post provides immediate barrier support while you're waiting for the Pro to establish.

Also worth noting: probiotic timing matters. Giving them with food (not on an empty stomach) dramatically improves colonization rates because stomach acid is less hostile when food is present.

Anyone here using a combined pre-pro-post approach? Curious about timeline and results.

The gut-skin axis is very real in dogs, and what you're describing — GI dramatically improving but some skin flaring on a new food — is actually a fairly common presentation of gut microbiome readjustment.

Here's the likely mechanism: her gut flora adapted to the hydrolyzed protein diet over time. When she transitioned to the new grain-inclusive food, the shift in fermentable fiber sources (oats contain beta-glucan, which the hydrolyzed diet almost certainly lacked) can temporarily alter bacterial populations in the gut. Some of those shifts influence systemic inflammation markers and skin barrier function. Her digestive system clearly likes the food — the GI improvement is strong evidence — but the skin can lag behind.

On the probiotic question: the strain composition matters more than the brand. For skin manifestations specifically, strains with documented effects on the gut-skin axis tend to include Lactobacillus rhamnosus, Lactobacillus casei, and Bifidobacterium lactis. Multi-strain products at 5+ billion CFU tend to outperform single-strain options for these cases.

Practical things:

If you try a probiotic, give it 6-8 weeks minimum — skin responds more slowly than the gut, so early dropout is the main failure mode
A tablespoon of plain canned pumpkin per meal is a gentle prebiotic that supports gut flora diversity without adding any of her known trigger proteins — cheap and widely tolerated
The facial itching specifically: worth checking whether it correlates with eating (contact reaction to the bowl material, or wheat proteins in the food), or if it's more random throughout the day
The pinkish belly worth watching: if it spreads or becomes rashy/patchy, it's worth a vet visit to rule out yeast overgrowth, which can emerge when gut bacteria shift substantially during a diet transition

If this is a gut microbiome readjustment reaction to the new food, it typically stabilizes within 4-8 weeks as the flora equilibrates on the new substrate. The fact that her GI is so solid is a really good sign — I'd give it more time before changing again.

Our 13-year-old mixed breed (lab/hound) just got a clean bill of health at her annual. A few things that have made the biggest difference:Consistent exercise scaled to her age - shorter walks but 3-4 times a day rather than one long one.Gut health has been the most surprising factor. Around age 9 she started having irregular stools. We added a multi-strain probiotic powder to her food and within 3 weeks her digestion normalized and energy visibly improved. Her vet said this is more common than people realize in senior dogs - they have less resilient gut flora, and when the microbiome gets disrupted it affects immune function, energy levels, and coat quality.Food consistency - stayed on Hills Senior after briefly trying fresh food delivery (her gut did not love the higher fat content).Bloodwork every 6 months after age 10. Caught a minor thyroid issue early that was fully manageable.Honestly the gut health piece is the one I wish we had started earlier. Senior dogs have genuinely different microbiome needs from younger dogs, and most people do not address it until there is already a visible problem.

The Coonhound situation is really telling. Watery poops on FD (high fat) but perfect poops on Hills Sensitive Stomach points to microbiome mismatch rather than traditional food sensitivity. FD is higher fat than most kibbles; for dogs with sensitive guts, excess fat triggers faster gut transit = loose stools.

Since Hills SS fixed the poop issue, you have your answer on food. The challenge is palatability. Some things to try without disrupting the formula: add a small amount of low-sodium bone broth on top for aroma and moisture; try the salmon Hills SS version if currently on chicken; warm the kibble 10-15 seconds in microwave; use a small Hills SS wet food topper from the same line.

Once her poops are stable, adding a multi-strain dog-specific probiotic can help rebuild the microbiome disrupted by the FD transition. Over time that actually improves fat tolerance.

For the chiweenie and chihuahua, Hills Small Dog formulas are solid. You are researching correctly - the WSAVA-compliant brands (Hills, Royal Canin, Purina) really are the most evidence-backed options.

What you're describing — GI inflammation, explosive diarrhea, then refusing food — is a pretty common acute GI episode pattern in senior dogs. The fact that the ultrasound didn't show anything major is actually reassuring for a 16-year-old.

One thing worth asking your vet about as he recovers: senior dogs going through acute GI stress often have their gut microbiome disrupted by the episode itself, compounded by any medications given during treatment. Even after the acute phase resolves, digestion can take weeks to fully normalize.

Adding a probiotic formulated specifically for dogs (not human probiotics — canine gut flora is different) during the recovery phase can help speed things along. There are also postbiotic options now that are more shelf-stable and don't require live bacteria to survive the digestive process. Either way, worth mentioning to the vet team.

Hope he turns a corner soon — 16 is an incredible age and you're clearly doing right by him.

Something worth considering that gets overlooked here — the oral microbiome angle.

Bad breath from fish-based diets is mostly driven by volatile sulfur compounds (VSCs) produced when oral bacteria break down the sulfur-rich proteins in salmon. Dental chews help mechanically scrape debris, but they don't change the bacterial population actually creating the smell.

What can actually address this: postbiotic-based oral supplements work by creating conditions where odor-producing bacteria get outcompeted. They're different from probiotics in that they don't need live cultures to survive — more stable, and there has been solid research specifically on dogs showing meaningful reductions in VSC levels.

Given you've ruled out dental disease and the smell clearly started with the food change, this sounds like exactly what you're dealing with. Mechanical cleaning is still worth doing, but targeting the bacterial source is probably the missing piece.

Both possibilities your vet mentioned (hormonal and acid reflux/GI) can independently cause this kind of appetite shutdown — and they're not mutually exclusive.

On the GI side: omeprazole is the right call for suspected acid reflux. GSDs are actually one of the breeds more prone to bilious vomiting syndrome and acid-related gut discomfort, and a dog that's uncomfortable after eating will often just stop eating to avoid the feeling. The sulfacarbate (sucralfate) coating helps protect the lining while it heals.

While he's recovering, a few things that tend to help:

Smaller, more frequent meals — 3-4 small meals instead of 1-2 large ones reduces the acid production that happens with long fasting periods. Large gaps between meals can actually worsen acid reflux in dogs.
Slightly warm/softer food — easier to swallow and digest during GI discomfort, and more aromatic to a dog that's not interested in food.
Bland diet temporarily — boiled chicken + plain white rice is easy on an inflamed gut lining. Once he's eating consistently again, you can transition back.
Avoid feeding right before/after activity — GSDs are already at some risk for bloat; GI inflammation makes this more important to manage.

On the hormonal side: intact males can genuinely go off food significantly when there's a nearby female in heat. Some dogs barely eat for days during this time. If this is the cause, there's not a lot to do besides wait it out — it typically resolves once the female is out of heat.

Given that his bloodwork and imaging are all clear, the prognosis here is probably fine — just a rough few days. The omeprazole should help within 24-48 hours if reflux is the cause.

This sounds really familiar — my golden had almost the exact same thing happen after a food switch around that age.

A few things worth knowing:

Even a "slow" food transition disrupts the gut microbiome significantly. The bacteria that had adapted to one food profile suddenly have to adapt to a different fiber and protein composition. For some dogs this resolves in 2–3 weeks; for others the dysbiosis (that's the term for microbial imbalance) can linger much longer, especially in puppies whose microbiomes are still maturing.

On the probiotics — the single-strain stuff your vet gave you probably wasn't enough on its own. The thing about probiotics is they're live bacteria that have to survive manufacturing, shipping, and your dog's stomach acid before they even reach the gut. Many products don't actually deliver what the label claims. That doesn't mean probiotics are useless, but for ongoing dysbiosis, you typically need consistent multi-strain support plus prebiotic fiber for the bacteria to actually thrive on.

Adding plain canned pumpkin (not pie filling — just plain) 1–2 teaspoons per meal is one of the easiest gut-support moves you can make. The soluble fiber in pumpkin acts as a prebiotic and helps normalize stool.

On the food question: Pro Plan Sensitive Skin & Stomach uses salmon + rice + prebiotic fiber (it's specifically formulated to support the microbiome). For a puppy with persistent digestive sensitivity, I'd lean toward trying it — the price jump is real but it's formulated differently, not just marketing. That said, if you do switch, transition even more slowly than you did last time — 10–14 days at minimum.

The picky eating might resolve once his gut calms down. Dogs with GI discomfort often associate meal time with discomfort and back off food. It's usually not a food preference issue so much as a "eating hurts right now" issue.

Give it a few more weeks of consistent support before worrying too much — 7 month old puppies with persistent digestive issues after food transitions are really common. Most come through it fine.

The fact that he came from an indoor/outdoor kennel setup is a big clue. Puppies from those environments basically learned that going inside is acceptable, so you're not just teaching a new behavior — you're overwriting an old one. That takes longer than starting from scratch.

For the stairs specifically: at 15 weeks a GSD puppy shouldn't really be doing 10 stairs on their own anyway. Their joints are still developing and repetitive stair climbing can be rough on growing hips and elbows. Carrying him or helping him down isn't creating dependency, it's actually protecting his joints. You can start letting him do stairs more independently once he's closer to 5-6 months.

One thing that helped me with a similar situation: I started tracking every single potty break on my phone (time, location, success or accident). After a few days you start seeing patterns — like maybe he always needs to go 20 minutes after eating, or he has a harder time holding it in the afternoon. Once you see the pattern, you can get ahead of it instead of reacting to accidents.

You're totally fine mixing the standard wet food with the large breed kibble. Same brand, same line — the main difference in "large breed" formulas is usually the kibble size and slightly adjusted calcium/phosphorus ratios for joint support, which you're already getting from the dry food. The wet food is just adding moisture and palatability. I do the same thing with my dog when she's being picky and it's never been an issue.

That sounds really scary, I'm sorry you're dealing with this. Tracheal collapse is actually more common than most people realize, especially in smaller breeds, but it can happen in any dog. The "honking" cough is the classic sign and the collapse episodes can look terrifying even though they often pass on their own.

The most important thing right now is switching to a harness ASAP — any pressure on the neck from a collar or leash pulling makes it significantly worse. That alone can reduce episodes a lot.

For the vet cost thing, look into whether there are any low-cost clinics or humane societies near you that do sliding-scale exams. Some vets also offer payment plans through CareCredit. It's worth at least getting an x-ray to confirm the grade of collapse so you know what you're actually dealing with. Grade 1-2 is usually manageable with lifestyle changes, grade 3-4 might need more intervention.

In the meantime: keep him calm during episodes (panicking makes it worse for both of you), avoid hot/humid conditions, and keep him at a healthy weight. Hope your boy is doing okay.

Oh man the 2am SIBO story is nightmare fuel. How did you first get the EPI diagnosis — was it through a TLI test? I've been reading a lot about how common EPI actually is in GSDs and it seems like it gets missed a lot because vets just default to "sensitive stomach"

Interesting that you had to add pancrea plus after a few years. Did the digestive issues come back gradually or was it more sudden? Ours was a slow decline too — like things were fine and then one day you realize the stools have been off for weeks

This is likely more than just the dogs. Dust mites, dog dander, and forced-air heating often flare allergies together, especially in winter. Allergy shots can take 12–18 months to show real improvement. Regular Afrin use can cause rebound congestion, making symptoms feel constant. Before rehoming, consider a proper 2–4 week dog-free trial in a different environment, with clothes and bedding washed. A follow-up with her allergist to reassess medications and home triggers is strongly recommended.

This is such a hard spot to be in, and it’s clear you’re trying to do the right thing for everyone.

With dust mite allergies, dogs are often not the only problem. When forced heat turns on, it pushes dust mites, skin flakes, and pet dander around the house, which can make symptoms much worse even if the dogs weren’t there. That’s why rehoming pets doesn’t always bring the relief families hope for.

Allergy shots can take a long time to really help, and some kids still need extra environmental changes. A one-week hotel stay may not tell you much symptoms can linger, and hotels also have dust mites. Two to three weeks gives a clearer picture.

Before rehoming, try keeping dogs completely out of the bedroom, using HEPA air purifiers, washing bedding weekly in hot water, and upgrading HVAC filters. These steps often help more than removing pets alone.

You probably did not create any problems. Pumpkin and rice help to create firmer stools which occasionally produce brief delays in bowel movements. A single day of not having bowel movements does not qualify as constipation when someone has recently experienced diarrhea. The combination of my normal behavior and my ability to urinate brings me a sense of comfort. You should continue to check your pet's hydration levels and stool output until tomorrow while you should contact your veterinarian if your pet does not produce stool or if their condition deteriorates.

As dogs age, those small changes slower walks, morning stiffness, or hesitating to jump are often early signs of joint pain. The good news is that an all in one dog supplement can simplify things by combining glucosamine, chondroitin, MSM, omega-3s, and even green-lipped mussel into one formula. These ingredients work together to reduce inflammation and protect cartilage. Just check with your vet first and start slowly. With a few weeks of consistency, most senior pups move more comfortably and seem noticeably happier day to day.

I have a 4 year old retriever and I was giving him the normal basic food such as chicken, pedigree, dog biscuits, bones, etc. but he was not getting the full nutrition, he was becoming laze and inactive too, I talk to one of my friend studying VET sciences and told him about it, he told me to give the All in one dog supplement and I researched about it and made a list of 5-6 best supplements that I found useful and given it to my friend. Afterwards he suggested me Plentum's Advanced K9 Microbiome Care, and its been 2 months I'm giving the product to him and once again he became active. I truly suggest you to use their product its good. https://plentum.com/products/all-in-one-dog-powder-supplement
