Okay, I have two dogs, but one of them is scaring me more and more by the day. First off, her nose is crusty just at the tip top part of her nose. The rest of her nose is wet and cold like any other dog. Also, she “eats” one of her paws. At first, I thought it was boredom, and I bought her rawhide chews and fun squeaky toys which she played with and chewed on, but anytime she rested she chewed on only one of her paws. And last, she is ALWAYS scratching her stomach. We give my dogs a pill monthy so I know she doesn’t have fleas/ticks/worms.
I should also mention she is a very small, fluffly dog. I was wondering if all of these things were related to allergies? We took her to the vet and he told us nothing extreme was wrong but I still think something is up. She’s an inside dog but she definetly goes outside for walks and to play or go potty in the yard.
So my question is, what is going on with my dog?! And what do her “symptoms” mean or point to?

My honey’s cousin has a German Shepherd that has just turned a year old. He takes this poor dog to the vet constantly and spent so much money on his baby, so this is not a story of neglect. Now, the symptoms and problems:
The dog has ALWAYS had runny poop (which is painful for her)
The dog can not seem to gain weight (no worms)
The dog’s shoulder is now popping out of socket (as of last night)
Other facts about the dog:
The dogs mother rejected her as a puppy, so Taylor got her when she was only 4 weeks old.
Taylor’s mother smokes inside the house and always has.
There is a 16 year old dog also living in the house with the dog, that is going to the same vet. Although I am not sure how this vet can’t see what is wrong with Baloo when they have helped Bandit live such a wonderful long life? (The older dog is still very playful and active, like he is only 8 years old.)
What could be wrong with this dog?? She is so sweet, its sad that she can’t seem to kick the problem. Taylor has tried different food, medications, powder from the vet, etc… Anyone else experience this?
