New yorkie showing aggression or jealousy ????
 

We have a full blood Yorkie that is 6 years old. Last week we were given a 2.5 yr old Yorkie. Since day one, he has growled at our oldest Yorkie that we have had for 6 yrs. Our oldest Yorkie can be just walking through the room and the newest one will jump on him and try to bite him, hurting him. Of course it scares our oldest dog. Also when I am holding the Yorkie that we have had the longest, the new Yorkie will act like he is sneaking towards us and he will snap at him, and bite him being so mean. Anytime we are showing affection to our oldest dog he tries to bite him. So unfortunately, our oldest dog runs around scared all the time. We can't leave them alone for one second for fear that the newest dog will hurt him. I just don't know what to do. I have tried scolding him but that does not work. If this doesn't stop, we will have to find another home for the newest dog.

Any advise would be appreciated. Thanks to all!

Are both males neutered? If not that could be causing some of your problem. When our newest male, also 2 at the time, moved in, he was aggressive toward the other 2. We "fixed" the problem and had him neutered. I also gave him a stern no, a loud clap, and pushed him away when he would try his shenanigans. Hopefully a few others will offer suggestions.

Our oldest dog we never got neutered. But the new dog is neutered.

This is a complicated issue bc the dog could be doing this for various reasons. If this doesn't resolve / get better within a couple/few weeks..then honestly, you really do need to have a good trainer come to your house, watch the behaviors, and guide you in a plan to make this better. I know it'll be a bit of an expense, but it should work if you have a good trainer.

I'd hate to see this poor little doggie shuffled yet again to another home, so I do hope you find something that works.

Does anyone else have some helpful advice for her re: training...?

I was hoping there would be more replies for this thread. My yorkie has just recently started showing aggression towards other dogs. She loves humans but she is slowly becoming more and more agressive with other dogs. At first is was just barking at other dogs and then she would loose interest but lately barking has turn to outright rage at seeing other dogs. She has only really liked one dog....another yorkie named Loki (I think she is secretly inlove with him). Loki is my coworker's yorki and for some reason, this is the only dog who she get's along with. They can play for hours together.

At first it just started out as barking at them but now has progress to attacking. Any suggestions would be welcome. I am thinking about taking her to puppy class to see if we can get it under control. It's getting to the point where I can't take her to the dog park. Just seeing other dogs is beginning to drive her berserk. She has never been attacked by another dog (at least not since she has been with me). Not sure if she has ever been attacked while she was with her previous owners.

She is 3 yrs and half yrs old. I've only had her for 1 yr and as far as I can tell, her previous owner took very good care of her. She did not come from an abusive environment nor was she used for breeding and was the only pet in the household as she is now.

Honestly it sounds like a dog who is unsure of what his role is supposed to be in his new home. Since no one else is volunteering for the role, he is trying to take the alpha spot in the pack. You need to correct him when he goes into aggressive mode to snap him out of it and to entrench your role as the leader. Get him when he is "stalking" with a sharp noise and a touch to the side if you are close enough. When he jumps on your older terrier, correct him, roll him belly up and hold him there for a minute or two until he stops struggling. He needs to learn that there are leaders in the house and his place in the pecking order is a little further down than what he aspires to be.

You have to establish first your authority as the pack leader then establish the hierarchy between the boys. The older dog who has been there longer gets fed first, petted first etc. Dogs are pack animals and the new pup is trying to assert dominance. You are the authority and you have to set the tone asap, be consistent and meet the defiance/aggression with a loud clap and "No" when you catch him. Eventually he will settle into his place hopefully. Small dogs like Yorkies tend to be territorial over their owners and they all don't like to share. This behavior is natural given the situation.
