My golden retriever is 1.3 years old, but since I got him at 3 months he has had constant on and off diarrhea. Typically his poop will be normal for about a week and then for 2-3 days he will get the diarrhea. I live in an apartment so I see everything that comes out of his body. He has seen the vet several times since I got him, but she says nothings wrong... but I don't necessarily trust the "vet". I've been wondering if his bowl problems are food related... He used to eat his food (canidae All Life Stages-Dry) willingly, but now he refuses to eat his food-sometimes he won't eat for 2 days. I have tried properly transitioning his diet to Acana several times but this only ends in watery diarrhea, so I have stuck with feeding Canidae. I walk him every morning and I work at a doggie daycare so he comes with me and plays for about 4 hours 2-3 days a week, so I can't see why he has no appetite. I have tired Calamine powder for the diarrhea, which I read in holistic veterinary book helps sweep his bowels, but after giving him this he had quite a lot of blood in his poop. I'm so lost with this problem as to what is wrong... He is very spoiled and loved and I am not a first time dog/golden owner, but I have never had any problems like this before. Is there anyone else who has had these same issues with their pup that could provide some insight to a solution or what worked for you? Thank you, sorry I know this is long.
