A few days ago we were having a BBQ in the front yard and one of the neighbors came over with his 2 dogs. Someone left the front door open and my Great Dane and Rottweiler mix came trotting out.. At first Laredo (the Dane) didn't notice the 2 dogs, he was just happy to see me.
When he did see the female dog he ran over and jumped on her and started attacking her. Both dogs were growling, but neither one was bit. Laredo didn't even hurt the other dog but he was on top of her attacking her for a good 30 - 40 seconds before we pulled them apart.
Then, about 15minutes ago I let him out back to go potty and he saw a different neighbors dog behind the fence and almost knocked the fence down trying to get at her.
What is his problem!? When he was a puppy he was attacked by some little Shih Tzu every time he went for a walk, so he hates little dogs now, but he's trying to attack all dogs. Even bigger dogs, which he used to like. This is the 2nd dog fight he has been in, but he has never hurt a dog, just jumped on it.
Could it be that he just doesn't have any manners around other dogs? He gets along perfectly with our Rottie mix and our 4 cats, but not other dogs. He's a wonderful dog, gentle with the kittens, a very friendly dog with people, he just has severe dog aggression.
Any idea what could be causing this? I know it's nothing medical, he just went to the vet not even a month ago and had a full check-up. It's really getting me worried, I don't want him to be like that.. Maybe he's not getting enough exercise or something?
By the way, Laredo just turned 2 years old and neutered.
