I've been combing the internet for months looking for answers for my german shepherd puppy's health problems. I have a German shepherd dog named Bear and I got him from a first year breeder who clearly did not know what he was doing. Half the reason I bought the dog was because it was so underweight and it clearly needed a good home.
He's a wonderful loving dog and he is my best friend but he's had health problems since I got him. He has had diarrhea his whole life, and the first thing I did was put him on premium puppy food, Solid Gold, to be specific. His diarrhea did not cease and the vet found coccidia in his stool. After coccidia treatment, he was still underweight and still having diarrhea. With no success for awhile, finally the vet (after 5 months!) decides to test for Giardia. Turns out he had it and so we began treatment for that. The treatment immediately ended the diarrhea. But as soon as he came off the treatment, the diarrhea came back. He's since been on the treatment three separate times, each with the same results. The treatment was the flagyl, if I'm spelling that correctly.
This last time, the vet put him on a duck and potato prescription formula dog food with limited ingredients because she was worried about the food I was feeding him. In fact, she didn't even know what Solid Gold was, which worried me greatly that my vet didn't even know what the premium dog foods are. I'm beginning to lose all respect I had for vets. Seems like internet research is far more valuable than asking a vet anything. They recommend Purina for Pete's sake.
So he's been off the treatment for 10 days now and on the new food for 17 days. He still has diarrhea and he is still underweight.
Some other important information:
He is eight months old now and weighing in at just under 55 pounds, which is about 11 pounds underweight for his age. And if you look at him, you can count all his ribs, and see his spine and hips plainly.
Despite him being underweight, he has never lost weight. He appears to grow as normal in height and length, and continually gains weight as he grows. He also displays no outward signs of being sick. He has a ton of energy and acts completely normal.
If anyone can help me solve this problem after months of scowering the internet, it would be greatly appreciated.
P.S., I realize that there are topics pertaining to underweight dogs already, but I've searched internet forums and website for months without posting or asking anything myself, so I must now actually make a post and ask with specific information about my dog. Thanks everyone.
