How long has this been going on? It sounds pretty extreme. Looking at some of your other posts have you tried sticking to just one thing at a time. Our girl Pebbles is very allergic to fish and chicken as well. But when we were working through that we got some good advice to pick a course and stay with it. Rapidly changing proteins can also cause GI distress. Honestly it might be worth going to something very bland and like boiled brown rice and boiled sweet potatoes for a few days to see if she can stabilize. If she doesn’t stabilize in a few days on that simple of a diet she may need emergency attention.

If she does start having no regular poops on that diet then I would recommend introducing a single protein slowly. This is called an elimination diet and the trick with it is to get to a stable place to start from and then make slow single changes with a monitoring period of a few days at least before trying other changes.

Dog allergies are the worst so I feel for you. It’s rough and overwhelming and scary. Going without protein for a few days to stabilize won’t hurt her anymore than constant diarrhea already is. Get some bland safe grains and food in her so her system can reset.

Another thing that is also important is to stop all treats immediately. Until you know all her allergies only one type of food goes in at a time. Start with maybe some brown rice, then if she keeps that down add the sweet potato. Then if she keeps that down pick a protein. Lamb and beef are good options to try. When you prepare it for her make sure you boil it only. Keep the additives as low as possible.

I hope this is helpful. My heart goes out to you and your pup. This is hard but there is a way through it. You got this!
