Sick Lab Mix

Question
Hi, my boyfriend and I adopted a 6 week old black lab mix puppy Tuesday. He was severely infested with fleas and had horrible gas when we got him, we were able to get rid of his fleas after a few baths and flea treatments. Yesterday he started to have bouts of diarrhea, he is still being very playful and doesn't appear sick, but every time he goes to the bathroom it is diarrhea. I was worried it may be parvo but he isn't throwing up and there is no blood in his stool. Do you have any idea what could possibly be making him so sick?
Thanks,
Emily

Answer
It doesn't sound like parvo, but he should be seen by a veterinarian. Take in a stool specimen for examination. The diarrhea could be from worms, coccidiosis, or giardia... all of which require medication to eliminate. It could also be from his diet, particularly if you switched food on him too quickly.
