Shrek is twenty inches tall and very bully with a large head. Shrek has a great disposition, he is great with other animals and fantastic with my grand kids. Although all of our dogs are good watchdogs, Shrek is our number one watchdog of the home. He does'nt back down from anything. Shrek has not failed me yet when it comes to breeding. He loves female dogs and understands his duty when it comes time to "mate". Everone who meeets Shrek falls in love with him, you just can't help it.
