My boxer puppy is about 6 months old and we are having problems training him. We have a lot of boxers in the past but this one by far is the worst to have to train. He is practically potty trained which is a big plus but he has a lot of other cons to him. Such as getting in to the trash, eating up my daughters toys, and the biggest thing that drives me nuts that needs to stop is when we take him outside he runs from you and will not come. You have to chase him around and when you finally catch him you have to carry him inside, he is getting too big to pick up. I don't really have the money to get a shock collar, so is there any other way we could maybe break him of this bad habit please help? We can't just put him on a leash because he hasnt been leash broken yet and he breaks off his collar.
