Yes, Vizslas are generally good with children and make great family pets.
The amount of food depends on the age, weight, and activity level of the dog. Generally, Vizslas require 2-3 cups of high-quality dog food per day.
Vizslas are active dogs and require a lot of exercise, so they are not well-suited for apartment living. They need a large yard or access to open spaces to run and play.
