Bruno is a 1 year old Boxer and
We have an older Boxer 4 years old
Bruno has an been exhibiting aggressive behaviors: when walking with him he will growl, and try to lunge and fight with other dogs
He growls at people when they are at our house
He nips at the vet when he has to visit - so we have to put a muzzle on him.
We are afraid that he will end up hurting another dog or bite a person - not sure what is the best training for him
Older dog is typically not aggressive at all- however the two of them together fight “play” very rough and seem to gang up and go into attack mode when when they both walk together and see any other dogs
