Common health concerns for Boxers

Boxers are a deceptively athletic large breed with a real joint load. Hip dysplasia, cruciate tears, and senior arthritis are routine. They are also one of the few breeds with a named GI condition: Boxer colitis, also called histiocytic ulcerative colitis, which is overrepresented in young Boxers and presents as chronic bloody mucus diarrhea.

Boxer cardiomyopathy is the major heart issue in the breed and is genetic, not nutritional. Supplements do not address it, but they do not interfere with cardiac care either.
