I have a one year old shar-pei and I had him vaccinated for rabies then i brought him home to meet my other 2 year old shar-pei. they got along good for a few hours then the new one attacked my old one and nearley killed him.can anyone tell me if i have the new one neutered will it calm his agression down?
In my experience with dogs who fought with their sire, and having them neutered, because I wasn't breeding them, it didn't make one iota of difference that the dog was neutered. It took me about 3 months of strict training to stop them from fighting. If you're not breeding your 1 year old it would be a good idea to neuter him anyway, and if there is going to be some kind of change in his temperment, it will be about a month after the surgery.
Yes, if you neuter him, it will calm him down in general. However, it sounds like what is happening is a dominance change over, when the younger attacks the older more feeble dominant dog in the house. I had this issue, and ended up putting my younger dog on prozac after going to a behavioral vet which explained this is common in dog packs or households. My younger dog was 9yrs old and was also anxious and suffered from separation anxiety while we were at work and liked to chew electrical wiring in the backyard pool. My older dog was 14 and deaf and she couldn't hear the dominant gestures/snarls that my younger dog was giving her, which ended up resulting in the younger dog being aggressive towards the older dog and biting her, causing many stitches and numerous massive vet bills. After a week on the prozac, my younger dog was calmer and more content with the dynamics of my doggie household. Yes, the younger dog was female and had been neutered/fixed for almost 5years before she began exhibiting aggressive behavior. The only other suggestion would be extensive training and/or muzzle the younger one while your at work. If the older dog, after the altercation, is now exhibiting submissive behavior towards the younger dog, then you shouldn't see anymore aggressive behavior because the younger dog is being respected and acknowledged as the dominant by the older dog. Submissive behavior could be the tail is at half mass when the submissive dog looks at the dominant, who eats first, when you put one bowl down, or who drinks first, who licks who, etc.
