My mixed breed large dog is three and a year ago was diagnosed with IBD and food allergies after several times having liquid diarrhea. Mainly after I let him have greasy fried people food (chicken nuggets from drive through McDonald's only one or two small ones). I did this with my last dog his whole life and he never had stomach issues so I never thought this dog would have an issue.
I rarely eat that stuff myself and mainly eat healthy fruits and vegetables and lean meat and poultry that I cook on my George Foreman grill which supposedly removed any more fat. But occasionally I'll eat something unhealthy like a cheeseburger or fries or pizza, very rarely and it never hurt my last dog to have a couple of bites so I continued that with this dog. Last dog lived to be almost twelve and was very healthy and active with no health issues until he died of a genetic spinal disease.
So the hospital specialty vets did a bunch of tests and put him on a bunch of meds and insisted I had to completely change his diet to a limited ingredient novel protein diet. Tell him that, he hates it. Now he literally won't eat until after midnight and I literally have to spoon-feed him and stand there with him for half an hour to an hour every night telling him to eat his dinner for every bite. The most I can get him to eat is one to two cups of dry food a day, usually one, and one large can. For an eighty five pound dog.which isn't much.
I finally figured out that his flagyll was actually causing his chronic diarrhea the past year. He had liquid diarrhea every day I thought it was from eating snow and ice. Vets said keep him on the flagyll. I ran out and took a couple of days to fill it and no more diarrhea, perfect solid poop. Now I took him off it and no diarrhea ever since. Took him off the antinausea meds too since he hates taking pills so much and he eats a little better.
He's still on a probiotic and his separation anxiety med.
I ran out of his special canned food and made it to the store too late so had to get what they had at the all night convenience store. Which was his favorite bacon and filet mignon flavored Alpo. He inhaled that in seconds the past two nights, and no more diarrhea! That's what I gave my last dog his whole life who was healthy. He still has his prescription dry food.
If it's not making him sick, should I keep forcing him to eat food he clearly hates or let him go back to food he loves? I've been giving him bacon treats all along for training and to improve his recall so the type of food hasn't changed. And I always give him a few pieces of whatever meat I grill for myself. It seems the key to his stomach is no fried foods more than the actual proteins themselves.
Money's definitely an issue now so cheaper food is better, but I also feel cruel spending an hour every night practically force feeding him food he hates. I'm very positive and praise him tons but I hated being forced to eat stuff I hated when I was a kid, good for me or not.
I've tried several different novel protein brands, the one he gets now is the only one he'll reluctantly eat at all. He's gone up to five days without eating a single bite when I tried to outstubborn him.
