All I can say is that I dont know of a dog I have ever seen that would tolerate a helmet and even less on motorcycle, unless it was all hopped up on downers.
If I see my brother get one of these for his Boxer (Chance) when we take the bikes out this spring, I'll vomit and then ask him for whatever he gave the dog. Although for Chance, I would put some custom chrome spikes out the top and a sticker on it or t-shirt for Chance that says,"If you can read this, the bitch fell off"
Get it.......... female dog........ bitch......
Ok Ok I'll go back to work.
