As you all know already I got my puppy and my other dog does not like him at all.. The puppy can be no where around and I try to pet him or pick him up and he starts growling.. If Jose (puppy) tries to play with him he will growl.. He loves my mom and even when my mom pets him or tries to pick him up, he growls.. What should I do about this?
The reason why he is biting your new puppy is because he jealous and also there's a new member in the family and doesn't like that. And he's also trying to show dominance in the pack between all of u including the puppy. If the dog is a-lot older he's trying to show your puppy who's the leader and not to mess with him. TRY to go to obedience class or train him, because as a young pup you have to groom him, pet him when he eats, and you have to eat first before he does, because if you give him his food first, he'll think that he's the leader. And also show him disapline. Do all this with the puppy before he ends up like the older one. Oh yeah and when you play with the puppy with a toy don't let him win, cuz that will make him more aggressive with other people.
This is what I do and I know others may not like it and have other suggestions but it is what works and I will do what works and my dog is very well behaved and friendly, it hasn't scarred her or hurt her one bit. I have no problem at all with her ever growling now. When she growls I grab her by the scruff of the neck and hold her down and tell her "NO!" she stops immediately then I rub her tummy and give her lots of praise while I am holding her down by her scruff and she has never done it again. My dogs know that I will not tolerate any kind of aggression whatsoever. Chloe is very gentle with Lily and she will let Lily crawl all over her now and she will play bow with her but she doesn't play bit her or get rough with her at all. Of course I never leave them unsupervised together.
When I first got Tucker, my dog Riley HATED him (Both Golden Retrievers). Riley would growl at him, and stand between the puppy and any other family member. It is just jealousy. If your dog does not have trouble with other dogs at the dog park, then I would suggest taking them to neutral territory (in serparate cars) and let them get aquainted in a park. I did this and now they are best buds. When they were still in the "getting to know each other" phase and Riley growled at Tucker, I would do just as somebody previously suggested and lie them on their back and say "NO!", and praise them when they get along. It will take about a good week of trying but it honestly worked for me.
I still have jealousy issues on occasion, however they are both boys and its usually over food or a toy. They seem to work it out themselves and everything goes back to normal again.
The funny thing is, I think Tucker (the puppy) is the alpha dog now. He walks all over Riley now like he's the boss. Its kind of funny because Tucker is half the size of Riley. It's like a 180 from before.
