Same thing happened with my old mans terrier couple weeks back but was hanging by the vein inside the nail so we just left it to fall off on its own,, didn't affect the bitch all we did was just kept it clean with salt water
Happened with me last night just walking through a field and these two Farley big built mongrels went for my pup and not for the first time and usually none of my dogs retaliate but my black dog wouldn't take no shit this time and got stuck straight into them, but that's what people get when they can't control there dogs and they just run up and start fighting
I got a direct granddaughter of Casper, her sire was Casper x snowy bred dog, I heard Casper did 17 from 17 hares over a month one year in January, not sure how true it is
I've got 2 and both have reasonably good recall when out with me and my other dogs but when other dogs are around takes a couple of whistles or raised voice calls to get them back to me,,
