Why Is My Dog Suddenly Acting Aggressive?

I live with my boyfriend and we have a 1yr old Papillon male. He is extremely friendly with all people and animals he encounters. He has had a few instances where he has shown aggression when trying to take food from him but this hasnt happened since he was a lot younger. In the last month or so he has snarled at my boyfriend twice and tried to bite him. Both of these times have been when the dog is sitting or laying right next to me and my boyfriend is trying to pick him up. It seems to me that he is being possessive of me and is trying to bite so that he is not taken from me, even just to go on a walk. Any other time the dog will run up to my boyfriend and greet him enthusiastically and he clearly cares for him a great deal, but I am concerned by this sudden change in his behavior. Our dog is crate trained and we have a young kitten as well that he treats like a loved brother. Overnight the dog sleeps in his crate and during the day he is left out around the house. He has never had professional training but knows “sit, stay, get down, lay down, get the ball, and drop it”.

  1. You have to show your dog that YOU are the leader of the household. Do not allow your dog to sit on your lap, while you are on the couch. This just shows him that he is greater than everyone else. Have your boyfriend walk in and sit next to you on the couch. If your dog acts aggressively, take him out of the room and place him on the floor. Repeat this process many times. He will eventually learn that agressive behavior leads to not being allowed on the couch. Good luck! 😀

  2. Your dog may just be being porotective over you. Mabey he sences something bad about ur bf but if he like him any other time he aint near you then he is just being protective so dont worry about him not liking ur bf but try to work with him on it so he doesnt hurt anyone (Like a small child) Good luck 🙂

  3. I agree with Julie, you have to become the “pack leader” cuz as of right now the dog thinks its the leader of the pack and therefor shows aggression. If you become the “pack leader”, then the dog will become more relaxed. There also can be more than one “pack leader”, so you should make your boyfriend also a “pack leader”. First you must exercise your dog regularly, as a dog with little exercise can become aggressive to more than just your boyfriend. After your dog is excercised you need to give your dog some discipline. If you are going to be the pack leader, you need to let your dog know that he cannot come onto the couch with you, unless he shows “calm submissive behavior”. Once you have seen that your dog is calm submissive, then you reward you dog with a chance to come on the couch with you. So remember in this order: “exercise, discipline, affection”
