My Whippet boy is 4 months old. He is currently on Acana Puppy & Junior, I would give him about 1 cup three times a day (morning, lunch, and dinner). I see different recommendations for how many cups a day he should receive, I was told a 4 month old whippet could eat up to 4 cups a day - but I recently discovered online they suggest up to 1&1/3 cups per day for his food&his size - This is a huge difference. His morning stools are usually fine but later in the day they are sometimes impossible to pick up, as they are like pudding, mustard-like in color, and extremely foul smelling. I have changed his feedings to 1/2 cup dog kibble and 1/2 cup boiled rice to try and stop the diarrhea, but it's not really helping.
Is his diet too high in protein/fat, or do you think he has a food intolerance (perhaps chicken)? Or am I feeding him the wrong amount/wrong intervals?
I'm leaning towards a food intolerance.
I've only ever had a small dog who 'grazed' as she pleased throughout the day. Help is very much appreciated. I just want to help the little guy.
