Hi, i took on a rescue yorkie just before xmas, approx age 6. He was in a foster home and unfortunately the people that handed him in did not provide much info on his background only that he was jealous of their two year old child although fine with older children, not unusual for yorkies by all accounts. However, I get the impression that the family that handed him in were not his original owners. This little chap is so sweet and is very obedient, has not done anything naughty indoors, not a peep a night and very quiet and loving. His foster carer kept him in a crate because of the amount of dogs she had indoors and she did say that he was a bit of a grumbly growler. We found out it was more than this not long after he moved in with us!! He has always been fine with me, but did growl and launch at my hubby a few times at first. We remedied this by hubby feeding him, walking him and generally taking the leader role. Dog loved him very soon after, follows him (and me) everywhere, so that was one thing sorted. However, he seemed to take a dislike to some individuals and starts growling at times if they walk past his bed or even say hello to him in some cases. This escalated from grumbly growling to throaty growling and snarling and unfortunately, he snapped at a few feet, making contact. Everytime we heard him growl, we sent him away to his bed. This again seemed to work fine for the last few months and we had no issues until the weekend when we took him away with another couple. He was fine for the first day, but second day wouldn't stop growling at the other man and tried to bite his feet 3 times, twice successfully. There didn't seem to be any particular triggers to this, unless he felt that the man was in his territory? But he kept growling and threatening, until he snapped. Everytime we sent him away to his bed, and he went grumbling away. It did seem to calm down after that, but still couldn't trust him. Just wondering if there are any ideas why he may be exhibiting this type of behaviour, he certainly tolerates some individuals better than others. Some other clues are that he barks when he is out walking at any other human or dog, when he is on the lead. When we let him off, he runs upto people and dogs barking his head off but doesn't do anything when he gets there! He also barks if me and my hubby cuddle or are too close to each other, and will bark if he is on the lead walking through busier situations, which is really embarassing. Any ideas on how to work on this. I've been reading up on the subject, but can't find any concrete solutions. Is it fear aggression/dominance aggression/lack of socialisation as a pup, previous ill treatment and trust issues, or just typical yorkie behaviour. If we could overcome the barking and the unpredictable snapping, he really would be a perfect dog. Being as he is a rescue, I really want to give him the chances he deserves, theres no way i would give him back as I love him to bits, but his "bad" behaviour makes it worrying if visitors come over and being out in public we always have the noisiest dog around!! Help!!! Thanks if you got to the end!!
