Meet Budreau

He's an American Pit Bull Terrier. Via Wiki:

The American Pit Bull Terrier is the product of interbreeding between terriers and a now-extinct breed of bulldogs to produce a dog that combined the gameness of the terrier with the strength and athleticism of the bulldog. These dogs were initially bred in England, Ireland, and Scotland, and arrived in the United States with immigrants from these countries. In the United States these dogs were used as catch dogs for semi-wild cattle and hogs, to hunt, to drive livestock, and as family companions;[1] however, some were selectively bred for their fighting prowess,[2] and starting in the early 20th century, they began to replace the bull terrier as the "dog of choice" for dog fighting in the United States.[3]

The United Kennel Club (UKC) was the first registry to recognize the American Pit Bull Terrier. UKC founder C. Z. Bennett assigned UKC registration number 1 to his own dog, "Bennett’s Ring", as an American Pit Bull Terrier in 1898.[1]

(I'll leave tthe curiosity of the reader making the remaining links to which the end-note numbers refer. They're on the Wiki page--W)

American pit bull terriers today successfully fill the role of companion dog, police dog,[4][5][6] and therapy dog;[7] however, American pit bull terriers in general have a higher tendency towards dog aggression[8] and constitute the majority of dogs used for illegal dog fighting in the United States.[9] The fighting reputation of pit bull-type dogs led the San Francisco Society for the Prevention of Cruelty to Animals in 1996 to relabel pit bull terriers as "St. Francis Terriers" (not to be confused with the "Terrier" mascot of St. Francis College in New York) so that they might be more readily adopted;[10] 60 temperament-screened dogs were adopted until the program was halted after several of the newly adopted dogs killed cats.[11] The New York City Center for Animal Care and Control tried a similar approach in 2004 by relabeling their pit bull terriers as "New Yorkies", but dropped the idea in the face of overwhelming public opposition.[12]

Budreau's a handsome, tawny, noble, head-out-the-window, 75-lb lap-dog. He loves the car and especially the truck. He sits beside me 'girl-friend close' at times. He seems to crave the contact and proximity. He loves to be UP, too, looking down. He'll rest atop the tallest accessible space available. They're enthusiastic dogs, and energetic, and they love to SPRING off their hind legs. If Budreau's leg had not been damaged (before he came to me; I don't know how it happened), I doubt I could keep him inside a six-foot concrete fence.

I will attest that, although he is the sweetest, most loving, most attentive dog I have ever had, and if I vet you, he'll be friends with all people, he's not good about other dogs.

So I have to keep him and Hanna seperate. And that is another story...
