I love dogs and I have 3 inside our house. But I never even think of bringing them along when I go biking. I want utmost safety for my dogs and being on the road exposes them to health risk - some stray dogs are spreading diseases. Aside from that, our dogs will just panic at the sound of a speeding vehicle, much more large vehicles like trucks. What I do is bring our dogs to the park and have the housemaid handle them while I do some laps on my bike. Our park is called oval because of the oval-like pathway.
