well his version any way lol. He loves dirt bikes and motorcycles, the noise, the speed, the excitment just gets him going. My boyfriend has a dirt bike. so we take Blaze with us every time, just for the fun in it for Blaze, and offcourse the boyfriend. So when the tank is almost empty, the boyfriend lets Blaze chase him around the pit for a bit. The BF does ride with a helmet and everything. Just not when the dog is chasing, so he can see where Blaze is better. Luckily Blaze has a exccelent recall, so if I get nervous I just call him back, and he is back next to me at the drop of a hat, or what ever the saying is lol. First I let him chase the ball while the boyfriend was out riding. for about a hour. Then, the race was on. he was so beat after running hard for about 20 mins. pretty much made him all relaxed and sleepy the rest of the night lol.
