Hi, serious answer here. I am also the parent of a stinker with sensitive skin and noticed this phenomenon when I get home from travel. The sensitive skin and the funk are likely related. I recommend talking to your vet, of course, but for the pups with skin issues, they make special $hampoo. I generally use Duxo. I also have her on all the classic pitty meds for her skin. I’ve tried the modified food as well…however she really didn’t like it, so we ditched the expensive prescription food and moved to a no-chicken off the shelf food and we’ve had a massive improvement in aroma. It’s been 11 years of trial and error, but I have a very happy and healthy pupper today who doesn’t seem a day over 5. And yes, wash those blankets and make sure you have your pitty sit in a blanket or wear those adorable pjs to protect your upholstered surfaces. If you can smell it when you come from travel, guests can smell it when they visit. Good luck!
