We have always 5-8 greyhounds in our house. We have a large house large fenced acreage. We have had peaceful pack.
I put the two newest in their crates when I leave the house. We supervise them when home. We don’t leave Lucy our big girl alone with a the new boy. They stand next to each other fine.
The new greyhound boy will let the others including Lucy walk over him and by him.
My Lucy walks away from any possible confrontation. She was spayed last year and somehow her tail is damaged she can’t wag it or use it to communicate to the other dogs. The new boy will have to learn from her posture and her looks.
I am starting to walk the two together. I make sure all treats are given first to Lucy and others he is last. He will have to learn his place in the pack. He was neutered two months ago.
Needed additional ideas to help them acclimate.
