Had an intact male for 8 years. Raised with our 3 kids. Nary a bite. However his mere presence kept many an unwanted visitor in their car until we came out of the house. Even when he was in a kennel with a hard roof...

Get 'em young, 5 or 6 weeks. Spend a BUNCH of time with them. YOU have to be the Alpha male, ALWAYS. If ya ain't a dog person by nature, look elsewhere. Definitely, find a reputable breeder.

Then enjoy one of the best friends you will ever have...
