This is Lucky, isn't he cute? He is a feisty 5lb chihuahua puppy. This tiny little dog bit Marley.
Yep, he bit Marley. They were playing in the park and he ran up behind Marley and he ended up with a mouth full of black fur, Marley turned around and snarled at him. I totally panicked and scooped up Marley. She was not hurt, however it totally freaked me out.
Lucky's owner is very nice and she was very apologetic, however she is not sure of what to do to stop him from nipping other dogs. He doesn't seem to not like Marley, they get along fine, until she stops playing with him. If anybody has any great advice for preventing this from happening in the future, please let me know.
