I call them beasts in a totally loving and jovial way. They are as affectionate as any breed of dog that I know of, and very playful. Sorry if I scared you by refering to them as beasts. They're so big and strong that it is a bit like petting a lion or something.
The was a dogo found in the midlnads some months ago. along with alot of pitbulls. all the pits were put down but the dogo had been kept by the police. http://www.expressandstar.com/2009/08/12/keeper-of-outlawed-dogs-spared-jail/ i hope im allowed to post this link
There isn't a Dogo mentioned in the article just a Japanese Tosa Inu which is nothing like a Dogo Argentino
