Boxer

The Boxer is a muscular, square-built working dog that is loyal, bright, sometimes silly and fond of children. It needs plenty of exercise, and with a few heart and joint issues in the breed, modest, lean homemade treats are the best fit.

About the Boxer

Origin and purpose

The Boxer took shape in Germany in the late 19th century. It descends from a smaller form of the Bullenbeisser ("bull biter"), a powerful hunting dog that German noblemen used to chase down and hold bear, bison and wild boar. Germany was among the first countries to use Boxers in police training, starting in 1904, the same year AKC registered its first Boxer. (AKC history)

Today's Boxer is a muscular, square-built working dog that is loyal, bright, sometimes silly and fond of children. (AKC breed page, AKC breed standard) AKC places it in the Working Group, and it ranked No. 18 on AKC's list of the most popular breeds of 2025. (AKC groups, AKC 2025 rankings)

Coat and energy

The short, shiny coat lies smooth and tight to the body. Colors are fawn (light tan to mahogany) or brindle, often with white markings, and a weekly brushing covers most of the grooming. (AKC breed standard, AKC, American Boxer Club flier)

Energy runs high: AKC says Boxers need plenty of exercise and ample space to burn it off. They also don't handle extreme heat or cold well. (AKC, AKC breed page, American Boxer Club flier)

Nutrition and weight

The AKC standard sets height (males 23-25 inches and females 21.5-23.5 inches at the withers, with no size disqualification) but no weight. The American Boxer Club says males may reach 65-80 lb and females weigh about 15 lb less, and AKC's breed article gives 65-80 lb for Boxers generally. AKC lists a life expectancy of 10-12 years. (AKC breed standard, American Boxer Club flier, AKC, AKC lifespan article)

The breed club recommends a good-quality dog food, usually kibble. Keep treats under 10% of daily calories and, as Merck advises for dogs prone to weight gain, count the calories in every treat. (American Boxer Club flier, Merck: feeding)

Big male Boxers can reach about 70 lb or more, which is Merck's cutoff for a large-size adult (32 kg), so ask your veterinarian whether your puppy should eat a growth diet labeled for large-size dogs. Merck prefers slow, steady growth and says adding calcium, phosphorus or vitamin D to a complete growth diet is rarely needed and may be harmful. (Merck: feeding, American Boxer Club flier)

Merck's table of inherited joint problems lists the Boxer for two knee conditions (see Health watch), so keeping a Boxer lean is a sensible way to spare its joints. (Merck: inherited joint conditions)

Health watch

  • Boxer cardiomyopathy (arrhythmogenic right ventricular cardiomyopathy): A heart-muscle disease that causes abnormal, sometimes very fast heart rhythms. Merck says it is almost always seen in Boxers and that affected dogs most often collapse because the rhythm keeps blood from reaching the brain, and the breed club says a Boxer that faints or seems unsteady should see a veterinarian immediately. No specific treat link. (Merck: heart disease, American Boxer Club flier)
  • Dilated cardiomyopathy: The heart muscle weakens and the heart enlarges, so it pumps poorly. Merck lists Boxers among the large breeds particularly at risk. No specific treat link. (Merck: heart disease)
  • Knee problems (cruciate ligament injury and osteochondritis dissecans): Merck lists the Boxer among breeds with an inherited slope at the top of the shin bone (tibial plateau angle) that leads to cruciate ligament injury, and among breeds prone to osteochondritis dissecans of the knee, a cartilage defect that can lead to arthritis. No specific treat link, but Merck advises counting the calories in every treat for dogs prone to weight gain, and keeping a dog with joint risks lean is sensible. (Merck: inherited joint conditions, Merck: feeding)
  • Cancer: The American Boxer Club notes that some Boxers develop various forms of cancer. No specific treat link. (American Boxer Club flier)

Fun fact

The name "Boxer" may come from the way these dogs bat with their strong front legs during play or self-defense, much like a prizefighter sparring. (AKC history)

Baking, treats and ingredients

Breed-specific baking notes

  • Bake training-size pieces. Even a 50-80 lb dog only gets a treat allowance of under 10% of its daily calories, so bake small pieces you can hand out during training rather than big biscuits. (American Boxer Club flier, AKC, Merck: feeding)
  • Go easy with puppies. For a Boxer puppy, keep homemade treats small and occasional so they don't throw off a balanced growth diet, and skip calcium-rich add-ons: the breed club advises against vitamin or calcium supplements unless a veterinarian recommends them. (Merck: feeding, American Boxer Club flier)
  • A biscuit is not a toothbrush. Don't count on a baked biscuit to clean teeth. AKC advises brushing a Boxer's teeth often to prevent plaque and tartar build-up. (AKC)

General baking safety (all dogs)

  • Never use xylitol. The FDA warns that xylitol can trigger a sudden insulin release and a drop in blood sugar within 10 to 60 minutes, and that it can turn up in baked goods, some peanut and nut butters, sugar-free gum and sugar-free candy, so read every label. If your dog eats xylitol, contact your veterinarian or an animal poison control line right away. (FDA)
  • Leave these out of every bake. The ASPCA lists chocolate, coffee and other sources of caffeine, grapes and raisins, macadamia and other nuts, onions and garlic, and raw yeast dough as foods to keep away from pets. If your dog eats any of these, contact your veterinarian or an animal poison control line, such as the ASPCA Animal Poison Control Center at (888) 426-4435, right away. (ASPCA)
  • Be honest about vanilla. Under the U.S. standard of identity, vanilla extract must contain at least 35% alcohol by volume, and other extracts may also be made with alcohol, so check the label. The ASPCA lists alcohol among foods pets should not have, so leave alcohol-based extracts, vanilla included, out of dog treats. (21 CFR 169.175, ASPCA)

Daily calories and treat budget

A typical neutered adult at 50-80 lb needs roughly 1,164-1,656 kcal a day (RER x 1.6, Merck Veterinary Manual), so treats should stay under about 116-166 kcal a day (the 10% guideline). Intact, very active, young, senior or overweight dogs differ, so ask your veterinarian for your dog's number.

Check an ingredient before you bake, and see how to portion treats with the 10% rule.

Treat size: For a typical neutered adult Boxer at 50-80 lb, keep treats under about 116-166 kcal a day, roughly 10% of daily calories.

Ask your veterinarian about

  • Boxer cardiomyopathy (ARVC)
  • Dilated cardiomyopathy
  • Cruciate ligament injury
  • Osteochondritis dissecans of the knee
  • Cancer

Breed tendencies don't mean your dog has a condition. Your veterinarian knows your dog.
