We just moved into a home where our dog finally has the yard to himself. Since moving in we've noticed he's become more aggressive with other dogs when they come over. Last night our friends Dane was here (they usually play well) and they got into a bit of a scuffle. Dalton (our dog) went after him and actually broke skin. We were inside so we didn't see what started it, but the fact that he broke skin really upset us.
Our old place had a shared yard with another dog and we never had this problem then, so not sure if this behavior change is due to our dog finally having his own yard and territory or what, but its obvious we need to address it. Luckily our good friends were easy going about the situation but we don't want it to happen again.
Has anyone experienced anything similar?
