I have several that I’m sure would protect me in the event that an unwelcomed visitor got into my house. Of course that same unwelcomed visitor would have to get past my 200+ pound Cane Corso and 180+ pound African Boerbel as they approached the house.
Good luck with amigo!
Amigo aka Diego, is one loud puppy to warn all ... the big dogs get up at that point.
My husband and I had four dogs; we used to joke about our “four tier defense system”; two of them were not friendly and liked to bite.
Two of them slept in in our bedroom, one slept in the hall and the Siberian husky who slept in the living room right by the front door (she looked like a blue eyed timber wolf) was not overly friendly either.
We didn’t have any problems.
