JRT male turning very aggressive.
I have a male JRT who is about 1 yr-old who has not been neutered yet. Just recently he has started this "territorial" thing where when my husband comes up to give me a kiss, he is right there in his face ready to pounce on him. He will also do this to me when I am tucking and kissing my son in at night. He has actually bitten my husband too during one of his "territorial moments." This behavior is new and I have no idea what prompted this. It is always at night and it is like a flip switches in him. He even growls at me when I am "tucking him in at night" and so I don't usually even pet him during night-time. We are planning on getting him neutered real soon, but I am hoping that this will take care of the problem because we can't have an animal around who we can't trust!! Any help or ideas would be great! We love this little dog dearly!!
Thanks. JRT lover from Oregon
