Don’t let your boxer get too much sun!

I just read an interesting article discussing the fact that boxers are particularly prone to the development of mast cell tumors, lymphoma and brain tumors. The white boxer and colored boxers with white markings should be protected from the sun as they are liable to develop skin cancer if allowed to burn. This hit me like a ton of bricks!


Lucy is an incredibly active boxer. We’ve known about the sun burn issue for some time but never knew that she was predisposed to skin cancer until recently. We try to monitor the amount of outdoors activity that she receives but it is difficult at times. We actively try to protect and guard against sunburn. One safeguard we’ve used in the past and still use when available is spray on sunblock, especially when we’re going to have her outdoors on trips or hikes. This seems to be working thus far.

Our daughter’s boxer Matty, has had some issues with mast cell tumors. She possesses a splash of white but not to the extent of being what is known as a bright boxer (boxers possessing a white splash covering more than 20% of their body mass). Matty is screened regularly and is currently undergoing treatment for the decease and is responding quite well as of this posting.

The bottom line of this post, I guess, is to make folks aware of the predisposition of boxer to the decease of cancer. Boxers should be screened for all types of cancer on a regular basis. There are tests that can be performed on boxers for all types of congenital predispositions. Breeders should perform these tests on all dogs that they are considering breeding. Regardless, get your boxer screened for cancer on regular intervals.
