Suddenly Aggressive With Our Other Dog Maddie is 9 months old and has suddenly become very aggressive towards Julie our 2 year old pug.
We adopted Julie 2 months ago and from the start she and Maddie were great playmates. Maddie has more energy than Julie but when she's awake, Julie is playing with her.
Within the past week Maddie has started a disturbing behavior. She will attack Julie to the point where Julie whelps and desperately tries to escape. It is NOT playful and it is without provocation. It had occured when Julie has a rawhide but it has also occurred without it.
Julie shows dominance behavior by humping Maddie fairly frequently but if it weren't for that you'd swear it was Maddie who was dominant because of her energy.
We have tons of toys for them and tons of rawhides (we have removed this temporarily in the hope of curbing the attacks). The each have a bed and they each have a crate. Julie is more of a lap dog so she often lies with us on the couch but we go out of our way to pay hands on attention to Maddie as well.
Any ideas as to what could be happening? |
