|These three boxers shows some of the color variation seen in the breed. Image is from Flickr.com under a Creative Commons license.|
- Too much white
- Over 1/3 of the dog is white, usually where the dog is mostly or completely white
- Dogs who are white except for a small colored patch are known as "checked"
- Solid black (either classic or flashy)
- Heavy brindle is okay, but fawn must be seen somewhere in the coat
- No mask
- The mask is considered "vital" for the "proper boxer expression"
- Lack of skin pigment
- Either of the eye rims/haws or nose

As for the last two mismarks, they seem to be the most unusual. The mask seems to be fixed or nearly fixed in the breed. Since the masking gene is dominant, it is quite possible that some boxers may very well be heterozygous for the gene. This would make it very possible for a maskless boxer to be produced if the right two dogs are bred together. As for lack of pigment, it is far from unheard of for a dog with white markings to have a loss of pigmentation to the skin as well as the fur. It seems that most boxers are born with a pink nose, which is also normal for dogs with white markings. Though most puppies will grow up to have a fully pigmented nose, it is very possible for pink skin to be left.
