Boxers are sweet dogs.... but be warned:
the in-breeding has caused them to have big issues with getting tumors, having heart issues, and skin problems as well. They aren't the healthiest of breeds. My sister's fiance had two... both died prematurely of cancer
.... they also snore and have really bad issues with farting. lol.
There are many great breeds that are a bit healthier and that are in a medium size range....
I have a Whippet.... they are the SWEETEST dogs you can find. A little timid, but you'll never have to worry about one biting a stranger or even another dog. THey are gorgeous, easy to house train, and generally very healthy dogs. (I am biased, but I do think they are one of the best breeds out there). They are a smaller version of a greyhound.... tall (20-22" to the shoulder) and slim, usually about 30-40 lbs.
Here's a Whippet:
(The Whippet is in the middle, smaller than the Greyhound, but bigger than the Italian Greyhound)
Other great medium-large breeds include:
- Soft Coated Wheaten Terrier
- German Shorthaired Pointer (they have a ton of energy, though)
- Border Collie - perfect size, amazing temperment, but highly energetic
- Siberian Husky
- Basset Hound (sweet, adorable, playful, easygoing, easy maintenance)
