If this happened at my house my American Bulldog/American Staffordshire Terrier/GSD/Lab cross would erupt, followed by my Great Dane, followed by a terminal statement from my good friend, Mr. Beretta.
We have 2 small 12 lb dogs who have the run of the house and they go off when they hear things that are not normal, but will shut up after a few seconds. Someone trying to enter the house they won’t. Last few nights they have alerted us to Coyotes of the animal type. If necessary the 12 gauge or the .38 Taurus Ultra Lyte would have come out.
The Lab part would step on the invaders foot and hold him until your Great Dane stood on him and drowned him in saliva and gross lickings.
Wow. That’s a lot of dog power. I’ve got my 90lb American Staffordshier /Bulldog/ Collie/ retriever mix and a Smith& Wesson ready to go as well. Plus a mean Cat lol.
I have 3 Rhodesian Ridgebacks, a mini Bull Terrier and a couple of good friends. :)
