Boxer (dog)
Boxers are good guard dogs. They are strong and like to run in open spaces. They can have a coat in various colors, such as fawn, brindle, fawn-brindle mix, white, white-fawn mix, and brindle-white mix. Males are 22-25 inches at the withers (tops of the shoulders) and the females are 21-24 inches at the withers. These dogs can range from medium size (65 lbs) to medium large (75 lbs).  Boxers are one of the most popular breeds of dogs in the US and over-breeding is a concern.
