A Boomer isn't actually a breed, but a cross between several small dog breeds. This allows them to vary greatly in appearance and temperament. Their exact personality depends heavily on the crossbreed used, and of course, each dog also has its own temperament. Generally speaking, however, they're playful, energetic dogs that enjoy human attention and can also be somewhat headstrong. If it's a crossbreed with a Lhasa Apso or a Shih Tzu , the Boomer can be a bit reserved or wary of strangers. Crossbreeds with a Yorkshire Terrier, on the other hand, can be particularly feisty and overconfident, displaying a pronounced prey instinct. Like many other dogs, a Boomer gets along quite well with children if properly socialized. It's important that children treat the animal with respect. At Felicanis, puppies are born in a calm environment and are well cared for, so they can grow up healthy and with a stable temperament. With a consistent and responsible owner, they're sure to have a happy life.
