When my boxer gets to play with a dog or puppy she gets so excited adn happy she foams really bad (she doesnt have rabies!)thank god she onlyn does that for like 2 days then she quits i really dont know if this is common or not
My pup would love a HAPPY entheusiastic friend. She keeps getting pinned down by agressive types. Poor little pup--she is so submissive and just wants to run and play with them. She wouldn't mind the foam at all!
MY friend's two boxers do this, ecspecially when they get really excited and are playing rough. I do not know why they do this, but I think it is normal. I have never noticed my own dogs do this, but I do not have boxers. Maybe, It has to do with the fact that they drool, but I am not sure. That is a good question, though.
