Beagliers will grow to be a small to medium-sized dog with a weight from 4.5 kg to 11.6 kg and a height of around 30 to 40 cm. Beagliers are most often tricolour; they can also come in tan, tan and white, red and white (Blenheim), ruby, black and tan, black and white or sometimes pure black. The Beaglier usually has a smooth, soft coat, but occasionally some Beagliers can have the longer coat like the Cavalier King Charles Spaniel parent. All beagliers need for grooming is the occasional brush and bath. Beagliers won’t shed much.

Beagliers can be described as affectionate, playful, good natured and loyal dogs. They love being around people (including children) and going on walks with people. They also love being around other dogs. They are also intelligent and confident by nature. Beagliers will alert their family to visitors or abnormal sounds by barking, so they serve as good watchdogs.
