I have a mutt that I adopted 7 years ago (when he was only 5 weeks old) from the North Shore Animal League in Long Island.

He's half Lab. Retriever and half Chow-chow.

He's mainly an indoor dog. I feel bad that I don't have time to take him out as much. But he loves it out there in the woods when I bring him hiking.

The problem I had biking with him is:

1. He stops and sniffs at every hydrant & lamp post (there are around 2 fire hydrants & 4 - 8 lamp post on a typical city block), so if I don't look for him, and if he stops, he'll get the wind knocked off of him by the leash that's attached to the seat post.

2. My seat is set at optimal performance riding for me (ie. legs almost straight when I'm at the bottom of my stoke), which means if he stops, I'll have to get off.

3. I have no wooded (forest) area to ride on. I can't take him off the leash because others may be afraid of him.

But I would love to bring him in an empty park and have him run next to me at a real slow pace for a while. Althought he's beginning to gray under the chin, ears & toes (he's all black), he's still full of energy!
