I got my baby (lhasa apso)when he was 2 months old from a breeder, we are a family of 5, mom and dad, me and my 2 brothers. We could never agree on one name for him and therefore my dog is addressed by different names by different family members. We had never had dogs in the house before and there were things that we did not know like how to train/socilaize him. He was never socialized with other dogs/puppies or people untill he was 1.5 years old by then it was too late.
He barks and lunges on dogs and people on the street but is really afraid of puppies.
He constantly barks he if gets to know someone else is in the house, we have to keep him locked in a room when we have visitors because he has bitten 2-3 friends who had come over
He sleeps in the same room as mine on the floor but moves to the bed by morning, he has free access to all the furniture but sits on the floor as well half the time
He is taken for walks by my dad and me, and food is usually given by my mother and me at times
He hates grooming - wont let me brush his hair,hates bathing. He becomes an innocent little lamb when I hand him over to the grooming parlour for his haircut. Those guys can do anything with him without even a small bark from him, he lets them!
He knows the basic commands like, sit, stand, come, hello...but wont do it unless he sees a treat in my hand
His biting started when he was 9 months old and continues till date, we got him nuetered when he was 1.5 years old, it helped control his aggression a bit but he still ends up biting family members once every 2 weeks, I am still clueless as to what triggers this, at times he would attack when he is being petted, once he attacked when I was adding his favourite treat to his food bowl, he would attack when someone walks by or even moves while he is sleeping/resting, he once attcked me when i answered a phone that was lying next to him on the bed, he attacked my father when he went near his food (food he does even like - it was his vetienery diet), he attacked my mom when she went to open the door for someone. At times he gets really possesive of certain things like if he manages to get a toothbrush or a shaving razor from the washroom, he wont let anyone come near him or the thing. What I have mentioned are certain triggers that I have noticed but most of the times I just do not understand the situation.. why he does what he does.
I am just clueless and not able to see any patterns in his agressive behaviour, he is a happy fellow most of the time, but then he gets these bouts of aggression which are totally unpredictable. Even though he is a small puppy, he causes serious injuries, lot of loss of blood and trauma to my family.
