For many years boxers were my absolute favorite breed and they continue to one I continue to keep. Just one at a time. They are precious.
When I first started to look for a dog breed after I lost my German shepherd I still wanted what was considered a protection breed. Doberman went to the top. I than picked up a book, can't recall it now, it might have been The Right Breed of Dog for You and I did the quiz and I discovered boxers were good with children, and are perpetual puppies. Playing their whole lives. I personally enjoy a confident clownish dog. Boxer were the first breed that was like that for me. Always coming up with goofy ideas, and always loving their people. They don't bark much, only when necessary. I don't like needless barking. They were a better fit for what I was looking for.
Boxers do have their health problems, but so do Doberman, so I picked what I thought was a better fit and never looked back. Occasionally I look at Doberman, but the larger size also discourages me. My boxers have been around 55-60 pounds with Rosie my current old lady being around 70 pounds. Boxers are portable and can fold themselves up into little beds like goofs. They make me laugh daily.
