The Vizsla is a family-oriented and affectionate dog. In fact, they are considered one of the most affectionate dog breeds. They are often called the “Velcro Vizsla” because they tend to stick by your side and want to be near their favorite humans as much as possible.
As one of the kid-friendly dog breeds, they tend to get along well with children and other dogs, but have a high prey drive and will need extra training and socialization around other small pets. Well-socialized Vizslas also tend to be open to strangers and warm up quickly.
Should a Vizsla Mix take after their Vizsla parent, you should be able to expect a similar temperament. The other parent breed will introduce their own quirks and potential traits, so you do want to ask the breeder about them. You can also meet the mother in person to see what her temperament is like and the behavior she is modeling for her puppies.
Socialization and training are essential for every puppy to grow into a well-rounded dog. Although the breeder should have started some training and socialization, it is up to you to continue to train and socialize a puppy once you get them home.
