i have had a 11 week old staffy x labrador puppy for two days now, the only problem is i have also got two cats, when i fetched the puppy in they all just looked a eachotha being weary but now the puppy has settled in when ever 1 of the cats come near her she chases them and tries to bite there tail i tell her no everytime and take her away but she keeps doing it. Also i tried to interduce my eldest cat to the pup by holding the puppy back and letting them sniff eachother but when the pup got close she tried to bite my cats face and my cat ran away. Is this normal behaviour for an 11 week old staffy x labrador puppy? And will she grow out of trying to bite them? Will they ever get on?
