I have a 10 week old GSD pup named Ranger. We have had him for 1 week. I also have a 7 year old golden, Dixie, and a 1 yr old bischon\****zu Jasper. They all get along and play together. Dixie puts them in their place when needed. My question is should I curb Ranger playing with Jasper. I dont want Ranger to grow up thinking its ok to chase small dogs. Jasper initiates at least half the time. It is normal puppy play and I would not be concerned with other breeds, I have had labs and goldens all my life but this is my first GSD. Any advice?
