I just rescued my 4th dog, he was born in a puppy mill, the guy had 128 puppies (all huskeys) with 5 mothers crammed into 5 pens !!! I adopted a beautiful boy, copper colored huskey. He had round worms and a condition called Giardia which I have never heard of before. Its caused by contaminated drinking water. He was put on meds and both cleared up. Have had extra stool samples done just in case. But my poor pup still has diaharea !! can't seem to get rid of it, only if I give him rice or oatmeal does it harden up. Vet is thinking that it may be a food alergy now, can anyone on here recommend a good food that isn't too costly that will help firm up his stools , remember i do have 4 dogs and they will all have to go on it, its way too difficult to feed a puppy seperately. He is still gaining weight so there is no danger there but I am always afraid that he will get dehydrated . Need to get rid of this damm diaharea !! really hard to poop and scoop

PLEASE HELP, ANY SUGGESTIONS WOULD BE GREATLY APPRECIATED !! :-D
