My little lady has tummy troubles. Now she has started this hacking, like she's trying to clear her throat and sometime's she pukes up clear/yellow phlegm. No diarrhea.In the past we had actual throw of food, itch skin, sick feeling. But we have seemed to move past that. So I feel like we are on the right track of eliminating stuff from food just trying to find the right one! The vet seems to think it's something to do with her break down of protein. She's on some meds right now but the vet says we are running out of options with dog food and need to try prescription food now. Either Hills i/d or z/d. And if all else fails they might have to put a camera in her tummy to run test which we CAN NOT afford. Has anyone tried this food or had a dog do this?
