Boxers are never meant to be outside dogs. Their hair coat does not grow thicker in the winter, nor thinner in the summer. It stays the same all year round, very sparse on the underbelly and legs, etc. Anywhere you read about boxers says they should not be kept outside. Many dogs can be kept outside physically (not saying I prefer that for myself, I don't) but some dogs cannot tolerate the extremes of heat and/or cold. They also cannot live outside in the hot summer because brachycephalic dogs overheat much more easily.

You are correct in saying that many dogs can life outside, as long as they are provided for, even if it's not ideal, but some breeds just cannot do so as well as others and those considerations should be taken into account when buying any breed. "What is it's intended purpose, can it fulfill that purpose and the way in which you plan to keep it, and is that the right breed of dog". The dog was bought to look mean, without consdieration of the fact that that particular breed is not meant to be housed outside in anything but moderate conditions year round, be it either heat or cold, and they also do not do well mentally being kept more isolated. They are far "needier" dogs than many other breeds, and that is why he's having problems.

I fully understand different people not seeing their animals as more than the animals they are, I do not feel that way, but they are entitled to it. The main reason I got upset myself was the way it was talked about, with it sounding like he didn't much care if she was bred or not, and didn't seem to realize the lack of socialization time was causing a lot of the problems. The dog has too much pent up energy, and she's getting blamed for being an active dog who hasn't been trained. It's not her fault.

Tim, I wish you luck in training her, and that things are able to settle down for you all, but if you really want to send her to your BIL, please don't let her be a breeder, it's really so hard on them. I have a dog that was used as a breeder, she came to me after, and she has had many health problems and illnesses because of it.
