I have a German Shepherd pup who is about 9 or 10 months old. I adopted him when he was around 7 months old. He has been dewormed, given all of his shots, on preventative, etc. I feed him foods like Blue Buffalo Large Breed Puppy and Innova Large Breed Puppy. He was still quite skinny when I got him, and I was told to give him puppy food for extra nutrients because apparently he was emaciated when they found him. I refuse to give him bad food (no corn, wheat, soy, by-products, unidentifiable meat, preservatives, etc.). I give him 2 cups of dry food twice a day mixed with a little bit of water to bring out the smell (otherwise he doesn't want it) - once in the morning and once in the afternoon, and he is the correct weight.
He burps a lot, which is funny to me... but some nights it's overboard. In the evening on random nights, he starts burping up what smells like a spicy fart... and it's VERY strong! One burp and the entire room smells! Sometimes he farts the exact same smell, and once he starts, he doesn't stop until the entire downstairs of the house is extremely stinky. Even though the exact same smell is the result, I've been close enough to tell whether it was a burp or fart, and he does both with identical smells. He does not eat his feces, though it would make you think twice. It also doesn't seem to matter whether or not I've switched his food brand. I always stay to the same quality, but slowly integrate the new brand anyway. Again, I'm feeding Blue Buffalo Large Breed Puppy and right now he's on a bag of Innova Large Breed Puppy. My mother's Miniature Schnauzer is eating a completely grain free diet of Blue Wilderness, Innova Evo, Orijen, etc. I was hoping to switch my pup to this kind of food soon (more digestible!), but I'm worried about his stomach. Also, when he starts emitting these noxious smells, he has diarrhea. He soiled himself in his crate today when I was only gone for an hour. The smell was just like what he burps/farts only magnified 100x! Poor guy had his nose out the vent hole and was crying until I got it all off of him. The whole house was putrid smelling and all of the windows and doors had to be open with fans running for 2 hours before it was even tolerable. He got a good bath... but I've never smelled fecal matter so strongly! This is no normal diarrhea/gas. What could be wrong with him? He seems to be in excellent health minus this one problem. Thanks.
