my dog started vomoting ,passing blood and losing weight last summer, he was in the hospital for 5 days and 3 parvo test came up neg, the vet never found a cause for his illness. since then whenever he gets hot the symptoms come back and also he keeps losing weight even though he has a great appitite. has anyone else ever had this problem with their dog, he is also negative for worms

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?

I just treated my dog for worms because she was looking sick and i saw the worms in her feces. I did that about 2 days ago but she continues to throw up clear liquid and has diharrea. She just had her 2nd week shots and I took her to the animal shelter where i got her and all the shots yesterday and they kind of just brushed it off as nothing, they were very busy and I don’t know if they just wanted to move along. Do you know what could be wrong with her or if the throwing up and diharrea are all symptoms of the worms and should be going away soon?
