15. Boxer
Boxers are well-known for their muscular build, boundless energy, and playful nature. Originally bred as hunting and working dogs, they possess a strong prey drive and high energy levels.
While they are often affectionate and loyal with their families, Boxers can also be stubborn and headstrong if not properly trained and socialized.
Without adequate exercise and mental stimulation, they may channel their energy into destructive behavior, including chewing and digging.
