My boxer has been with our family since birth and is now ten. My parents want to bring another boxer into the house because the vet says Tosca will live for another 2 1/2 years. Tosca is good with people, and has been the only dog since we brought her into our home. Will she be hostile towards the new puppy? I've been told boxers are territorial towards other animals.

Hello...I dont know boxers..and there are a few here who have or breed them...I know i have heard they are great family dogs. I have shepherds and they do ok with other dogs IF they are different sex's and or raised together. I hope the boxer folks chime in....good luck...
