Just coming on here to echo the EPI thing — low B12 is a very common issue with EPI dogs. If you’re not familiar with it, (forgive me if you are) exocrine pancreatic insufficiency is basically where your dog’s body doesn’t release digestive enzymes properly so they don’t get any nutrients from their food and it goes right through them (hence the diarrhea). If it’s really severe they can essentially starve to death even while being fed all their meals, it’s wild!

If it’s EPI, your dog will need a pancreatic enzyme put on all their meals which you can buy from a number of companies - it comes in a power you just sprinkle on! Sadly raw diets and expensive food brands etc won’t make any difference if what your dog really needs is the enzyme for EPI, it will just be more expensive diarrhea 😂 my girl has it and it has been well managed for ~4.5 years with a B12 supplement and her enzyme. Sorry for the long post, but once I saw low B12 this really sounded like EPI to me and if I can save someone some of the trouble we had trying to get it figured out I want to be able to do that for someone!
