I’m not sure what my Cane Corso would do. Of course at his size (180 pounds) and bark, he would definitely make some one stop in their tracks. However if the would be intruder looked closer they would probably see his tail wagging faster than a cocker spaniels.
He used to sleep in my room but his snoring and farting all night would wake the dead as well as keep my wife awake all night. So we moved his bed outside my bedroom sliding glass door so now he sleeps right there. You can still hear him snoring though but we don’t have to deal with the farting.
LOL! Mine, the female, wants to sleep in bed, head on her own pillow. The male at the foot of the bed and yes, both snore, sounding like revving engines...I have earplugs...
My baby girl was an English Mastiff (124 pounds of devoted love and a killer instinct when necessary), I always found her snoring to be quite restful, her farting not so much.
