This small dog stands 20–38 cm in height and weighs about 7–14 kg on average. It is not too small nor too big. Its small size makes it an appealing pet for those living in smaller accommodations, which also adds to its popularity.
As mentioned, the puggle inherits both pug and/or beagle traits. This means that some puggle puppies may have more beagle features, whilst others may look closer to a pug. However, this canine generally has a pushed-in, brachycephalic face, expressive eyes, and droopy ears, which is reminiscent of its beagle genes. Its body is thick, with legs on the shorter side. Its loins are rounded and well-muscled, and its back is level and firm. Its short tail curls over its back, and is perky.
Its short, straight-haired coat comes in a variety of colours, which also means there are black puggles. Most of them, though, come with a fawn coat and black mask. As such, it looks like a miniature version of the English mastiff.
The puggle has minimal grooming requirements as its coat is short and thus easy to maintain. Its facial folds or wrinkles need to be washed or wiped down, though, to prevent bacteria build-up.
