Alright, so this is the first time I owned a dog and we got him when he was 8 weeks. He's always had a sensitive stomach and couldn't figure out why he was having such bad gas and diarrhea here and there. The vet recommended I put him on a diet strickly of rice and boiled chicken so for yhr last 3 days now that's what he's been on, now it seems like it got much worse. His diarrhea has turned constant and to straight liquid shooting out, he starting to throw up a little and he can hardly contain himself when he has to 'go' and sometimes doesn't make it. His nose I've noticed is a bit swollen, not sure though if that's from him trying to get the harness off when I take him for walks or an allergic reaction to possibly chicken? He just had stool samples and blood work done about a mth ago, everything came back fine. Should I try the Lamb and rice mix instead? I heard that was better to try if your dog is sensative to certain foods or allergies. He's a lab/husky mix, about 55 pounds.
