We adopted a 2 yr. old Lhasa apso from the pound in may. His name is Pistol, his last owner was a senior citizen & litter box trained him!! He also was hardly ever outside!! When my boyfriend brought him home, he took to me immediently!! Everyone else that comes to visit, he chases them & bites @ their ankles & keeps growling & barking @ them...he is relentless & won't give up!! He gets along with our other dog & r quite the buddies!!! Can anyone tell me if they have had similar problems & what I could do???
