Do all Boxer dogs drool?

No, not all Boxers drool. Drooling can vary widely among Boxers and may be influenced by genetics, anatomy (such as lip and jowl size), age, and health. While Boxers are not known to be heavy droolers compared to other breeds, such as Bulldogs or Saint Bernards, some Boxers may drool occasionally, particularly in response to excitement, anticipation of food, or during hot weather.
