Hey, we just got a great pyrenees puppy today. She is 8 weeks old. We got her wormed & put flea Med. on her. She was fine all the way home (which was an hour drive) After we got her home she acted fine until she slept about an hour and then woke up. Then she went and used the bathroom and it was very watery like diarrhea! Then later she threw up. Could it be from getting wormed & all?? She had never been wormed or given any shots at ALL before we got her. So maybe this is all just 'too' new for her??? Also she had a little bit of blood in when she went to the bathroom.
