Jack Russell Terrier
The Jack Russel is one tenacious terrier. It digs, barks, jumps and hunts with relentless abandon. The Jack Russell Terrier (JRT) was bred as a hunting dog. Your garden or living room is fair play if your JRT is after prey. Spiders, mice, and other bugs will be hunted to extinction, and your home will be scratched and dug up.

Climbing and jumping over fences is one of its strengths.

Due to breeding, Pit Bulls are aggressive. As one of the most aggressive dog breeds, it will never back down from a fight with another dog. It’s a fight to the death that Pit Bulls rarely lose. A leash is indispensable for Pit Bulls; this powerful canine should be leashed at all times.
