Training

Jack Russell chihuahua mixes are not renowned as trainable dogs. Often stubborn to even a strict owner, this breed is going to take a little work to get in hand. The key is to start when your Jack Chi is young and to provide positive reinforcement. Dogs respond very well to reward and not as well to punishment. The sooner your Jack Chi associates certain behaviors with reward and attention, the closer you are to a well-behaved best friend.

The Jack Russell chihuahua mix shares its shedding tendencies with its low- to moderate-shedding parents.

This breed is fairly low maintenance. To keep its coat healthy, brush your Jack Chi a few times a week and bathe on an as-needed basis.

Bred to suit more modern lifestyles, these dogs can live just about anywhere. They are wonderful apartment dogs but will also be happy on a large plot of land. Jack Russell terriers were bred to hunt foxes, so Jack Chis love wide open spaces.
