Big dogs have always come off a little scary, especially if they’re barking viciously at you. Most big dogs are bought by humans as guard dogs, to protect the household (or sometimes even the owner) from intruders or any unwanted people. Don’t judge a book by its cover. Just because a dog is big, it doesn’t necessarily mean the dog is fearless. Take this adorable boxer in the video below for example. His size may be drastically different from the feather he’s trying to touch; yet he still appears to be afraid.
