Hi everyone, ive got a border bitch puppy who's 6months next week. Wanted to ask if there was any preference as to age to entering a dog to rats. She's very game but id hate for her to be put off by a bite at a young age. I had caught a rat in a cage trap in the barn and got the whippet to sort it out like normal, took the border along. She was wining and snapping at the caged rat. And when the whippet was shaking it she latched hold, took it from his jaws and aggresively crunched the pretty much dead rat as she pranced round proudly. What do you think, she ready for a live one?
