IBS Dog age 7

Question
our dog has been diagnosed with IBS, He is on prednis, azathioprine and currently metronidazole for diarhhea (2+weeks). I fed Blue (lamb) dry mixed with home cooked. I make 1 cup pork, 1 cup barley, 1 cup rice, 1 cup veggies, 1 cup sweet potatoes, cannola oil. I do add bone meal powder, multivitamin, milk thistle etc. He is not doing good. Losing weight again, shits, not eating etc. It has been under a year since this all started and I to am disgusted with dry/commercial foods. I recently switched to wellness (ocean variety), dry as I thought my dog is just sick of the same old stuff. He acts like he is starving but wont eat dry or what I make. He will steal anything else? We were told no beef, chicken, corn, wheat, soy or dairy. Other than expensive game meats I have no options to affordably feed my dog? I am at wits end and already lost one dog last year to liver failure...which I also attribute to bad dog food. I dont mind home cooking even though no one seems to know how much to feed. Or when they do tell me how much it seems like massive for a dog that is skinny as heck and wont eat half the time? Any suggestions? Raw diet? We have also done B12 shots and shots of prednis which no longer seem to re-stim him either?  Thanks Dawn

Answer
Dogs are carnivores and things like barley and canola oil will cause problems. Barley is one of the worst as far as being digestible to dogs. Why were you told no beef or chicken? Raw dairy is fine but pasteurized is not. Soy isn't good for dogs or people.

I always prefer raw and especially do that in situations like yours. For now try pork. You can get it rather cheaply if you look around. I feed pork chops, neck bones, ribs, etc.

How much does your dog weigh?

If there was no really good reason not to feed chicken I'd get him some necks which have a lot of bone. Bone acts to stop diarrhea but too much will stop him up. Real bone beats bone meal powder any time.

Since you need to know what agrees with him it's best to feed only one source of protein for the first week or two then add a second source. That way you know exactly what proteins are bothering him and which are not.

As for all the drugs he's on please make sure you don't just stop them dead. Prednisone in particular must be withdrawn slowly.  

The best oil to give a dog is fish body oil. He really doesn't need anything else.
