The American Pitbull Terrier and the Boxer are both medium to large-sized dog breeds, so the Pitbull Boxer Mix will inevitably be a medium to large size dog as well.
The average adult Pitbull Boxer Mix will be about 50 to 80 lbs and about 20 to 26 inches in height at the shoulder. Depending on the size of the parents, it is possible to find Bullboxers that are smaller or larger than this, with males typically being larger.
Since the Bullboxer is a hybrid, it is hard to predict with certainty the parent a Pit Boxer Mix puppy will take after. Some will look like the Boxer parent, others like the Pitbull parent, while others will be a mix of the two.
That said, many Pitbull Boxer Mixes will have a large head, a longer snout like the Pitbull, and the Pitbull’s wide body coupled with the Boxer’s deep chest and strong legs. Some will acquire the Boxer’s semi-pricked ears, while others will have the Pitbull’s short and cropped ears.
The long snout means your Pitbull Boxer Mix is unlikely to be affected by the respiratory issues that affect brachycephalic breeds like the Boxer.
Bullboxers have a single, smooth coat with short hairs. Their coats come in a wide range of colors, including white, tan, brown, red, yellow, and other colors that exist in the parent breeds. This means you can have a black Pitbull Boxer Mix, or even a Pitbull Boxer Mix that is brindle.
