Humans, chimps and other primates have all been shown to be susceptible to contagious yawning. Previous research has suggested that dogs are, too, unless — according to newly published findings — that dog is a puppy younger than seven months.
Such a dilemma. You have a dog that loves to walk, but he's so powerful that a standard leash and collar won't work. Relax, don't worry. Just grab a supercollar.
I have admittedly mixed emotions about sending dogs into combat on our behalf, but as long as we're sending man's best friend into dangerous situations, we might as well give him badass armor.
