My neighbor had a beautiful boxer. I saw him everyday. he would consistently pull on the leash to chase cars. unfortunately he was an extremely muscular dog of only 2 yrs. Of age and pulled the leash so hard, his owner, who was very fit, fell down & her boxer chased the car down the street approx. 1/2 mile only to meet his demise. it was quite sad, but that was the only behavorial issue he had. :( boxers are a wonderful breed of dog. but you must show him who the leader is. ♥nassy pls. Rate my answer. thank you.
