LLD "little dog disease" ?

I haven't personally. But my dog has been attacked by a Jack Russell Terrier. Poor Brasky...he's SUCH a good dog and I've trained him so well that he just laid there and cringed while the JRT had ahold of his head. I guess thats one of the consequences of conscientious training. It was over quickly and if that dog even so much as LOOKS at Brasky wrong these days...Brasky just wants to rip him to pieces. Otherwise he LOVES to run and play with other dogs. I'm surprised to this day that he gave the JRT a free p. I guess he knew that with the JRT being only 14 pounds and himself being 100 pounds it wouldn't be a fair fight...but that was the LAST free p that dog ever got!
