recently my 16 yo step daughter moved in with us and brought her 5 yo nuetered Chihuahua Junior with her. he was snippy and growly to begin with, with people and animals, but then we added Axl, a 5 yo papillon, also neutered and it's gotten much worse. Junior REALLY doesnt like Axl to even get near him, he growls and snaps at him even though Axl is very submissive.
now he's started pooping in the house, something that wasnt a problem in the past. anyone have any ideas on getting him to stop?
