Of course you wouldn't know of it because there isn't one.
Because such a dog like that don't exist. If it does, there will be laws to restrict them in public Im sure. Common sense tells me a dog realistically that large can't be stopped with human strenght holding a chain. And look at that tiny rope he's holding!
Hey I have a pit bull weighing 60 lbs. that dragged my girlfriend with him to attack a dog that I payed hospital bill for so I know.
I thought I'd make you happier by letting you know someone did read the whole thread before posting and that someone knows where you are coming from.
Even if he was real.I wouldn't like to be his keeper.He would produce 4lb stools.If he relieved himself in your house it would be like having one of your aquariums spring a leak.
