Please please please can anybody recommend a dog trainer/behaviourist that would be willing to take on a boxer that has some (query) aggression issues. Hes a 3 yr old male un-neutered that has killed a family pet parrot. Fights with the other male dog in the house, has growled but not bitten the family members and yesterday he got out and went for another dog Vet has advised PTS which will take place this afternoon :-(
