I thought it was his commentary that was funny considering the dog--not the dog that was funny. I found it odd the way the dog wasn't reacting to being held. Just hands over its head. A lot of dogs hate hands over their heads--like Vlad. People can pet him on his side, chest and under his chin, but not over his head.
Some Chihuahuas are just like that. Vicious little critters that bite everyone including their owners' children. They can be very domineering little brats. If I was going to ever have another small dog of my own, it would be another miniature schnauzer.
