I always find the Tibetan Mastiff terrifying. I know many people keep them as pets but they are just so muscular and powerful. I don’t think any pet owners could control them if they start running amok. This is when I started to imagine a gigantic version of a Tibetan Mastiff that is built for war. They will wear spike armor and charge into the battlefield without remorse, destroying enemy ranks with ease. Due to how strong they are, no one should ever engage these large dogs in melee combat. Long-range weapons are advisable in these scenarios.
