Least Intelligent Dog Breeds; Sorry if Your Dog’s Included

The massive Mastiff is a dog of courage and immense strength known for being a protector and yet a kind breed. They can be intimidating, but Mastiffs are known for being lovable companions and make a great family dog. Due to their size, it’s best to begin training and socialization as a puppy, while they are still small enough to control. If you’re considering getting an English Mastiff, do not take the commitment lightly, they tend to be wary of strangers and can do a lot of damage should they become aggressive.
