Hey guys, I'm currently considering adopting a dog as a guard dog for my house. I want a breed that looks intimidating and would make any intruders think twice before attempting to break in. I've narrowed my choices down to a Doberman and a Mastiff, but I can't decide which one looks scarier. Both breeds have the potential to be excellent guard dogs, but I want to choose one that has an intimidating presence. Can anyone with experience with either breed help me out and give some insight into which breed looks scarier? Thanks in advance!
