My 14 month old was playing in my backyard with 2 other neighborhood dogs when Chivas just kind of went off on one of the other dogs. I didn't see what happened, if the other dog did something or if he went for one of Chivas' balls. They have played together lots of times before this and have never had a problem. This was the first time that we were in one or our back yards. Usually they just play in the street and front yards. He also goes to the dog park at least twice a week and never has any issues. It scared me a bit cause I have never seem him act like this and really don't like it.
He isn't fixed yet...could that have played a role? Should I be worried?

" I didn't see what happened, if the other dog did something "

Anything besides suggesting that you supervise all other occasions would be guessing.

IMO, young intact males may have a faster trigger due to the testosterone. (May become more easily aroused during play) which with constant supervision from you could be defused before anything escalates.
I think it all has to deal with training. He needs to learn what is acceptable when he is having testosterone surges and that can only happen under your guidance.

Since you dont know what happened and he has never had any issues with dogs in the past, it may have been something that happened that caused it. When dogs are not neutered around dogs that are neutered it can cause some problems. From now on I would keep an eye on him at all times around dogs to see if something happens again. Are you going to get him neutered?
