I go with 'a willingness to continue'. But check this out.
Disclaimer: I am not into non-game bred dogs fighting or saying a regular old mutt can be a game dog but this is what we are dealing with at our house.
Short story long to preface the topic.
When my son was 12 he wanted an English bulldog. We bit the bullet and bought one. She turned out to be quite the dog to have in the house. When my son was 16 he and his girlfriend find this 6-7 week old pup on the side of the road. They went door to door and he was not claimed. He ended up here. Fast forward some four years later. The English bulldog bled, flagged and I checked her every day for another 8-9 days. My 'heat cycle checking' Beagle gave her a once over and was not interested. Next day I turned her into the back yard. I am not sure if it were the immaculate reception, excpetion or conception. 63 days later she had 9 puppies. Raised every one.
Tanner is a long lenthgy brown brindle dog that covers the 2 acres of fenced in yard in no time. A speedster. She is typical English Bulldog. 6 of the 9 recreated the American Bulldog. They could have been easily passed off and no one would be the wiser. One looked like Jimmy Boots spit him out and the other two looked like plain old brown mutts. Thick and beefy but mutts. All of them were placed in homes except for two. One of the brown mutt dogs lives in the back yard with his Pops Tanner.
They fight on occasion. It is not the cur snapping slap happy yard dog fight. These dogs are taking hold, tucking their legs back, and getting to it. The first time my son and I separated them and it went months before it happened again. Tonight they went on each other while I was away. My wife struggled but could not separate them. They fought for the entire 55 minutes it took me to get home. They were blown hot, gasping, yet still both in hold. It is 80 degrees out.
I separated them and they still wanted to go. Being cur dogs one snapped and my son let him go. He made a 1/4 acre scratch from one side of the yard to the other back into hold.
They are now in two brood boxes. I will buy kennels for them tomorrow as placing grown dogs is basically a fat chance.
If the same story was told about two bulldogs, 55 minutes, blown hot, gasping, separated and made a straight and true scratch over a 1/4 of an acre after being apart for several minutes game is a word that would come to mind.
Never seen anything like it. I have seen tons of yard dogs snap and flail for a matter of seconds but never over a miute or so. This was 55 minutes of being in hold, in the heat and both really wanting some more.
My son who is not in the dogs at all, said maybe you should switch up to my Englsih cross dogs. Too funny.
Short story long.
