Since an unfortunate incident in the yard in April where our EBT (Brian) ran into our younger Greyhound (Teddy) while chasing after our young Bullwhippet Lurcher (Roxie) things have been really sour between Teddy and Brian. Teddy will bark and growl anytime he senses Brian coming downstairs in the morning or into the kitchen in the evening while he's in the sunroom with our other Greyhound (Chubby). Brian will often tense up and bark and slide towards the door dividing the kitchen and sunroom but can be redirected away with a treat scatter. Teddy on the other hand will not take any treats or respond to attempts at redirection. Teddy has also inflicted injuries to our other Greyhound Chubby on a number of occasions. All of the dogs and the female lurcher are neutered. Chubby (11) is with us 5 years, Teddy (5) we have nearly 3 years, Roxie (2) we have almost 2 years and Brian (4) we have since last October. I'm operating a strict management so that Brian and Teddy don't have an opportunity to escalate the situation with each other. I have started to let them see each other for a short periods with a baby gate barrier between them. Teddy acts tense and stressed when he sees Brian and growls.

Prior to Brian being added Roxie used to hang out of Teddy's collar, pull and drag him around even though she's significantly smaller than Teddy. Teddy lets Roxie do what she wants and has yet to lash out at her. This was particularly bad last year after Roxie was neutered and in her adolescent stage.

Roxie/Chubby/Brian seem to get on well individually with each other and Roxie - Brian are like best buddies energy wise and play style. Brian and Chubby get on pretty well too but we are careful with their interactions given the disparities in physical strength and age differences.
