We currently have a 11 month old female toy Poodle. Gracie is her name and she stole my heart early on and continues to be my baby girl. My wife and I decided to add to the household by adding a new 10 week old male toy. Gracie has not responded well to the new addition. I’ve read that it usually is a 3-4 week transition. Gracie growls, jumps on, and tries to repeatable pin the little boy. Is this a normal transition?
