Ive got two dogs that go with me almost every time I bike. My older one, a 6 year old black lab, has been my riding buddy since I first got on a bike. She’s got seperation anxiety so she never gets more than a few feet from me. My puppy, a black year old mut, gets a little excited and distracted. She’s likes other dogs and attacking my lab randomly.
To train your dog, this is how I am training my puppy, get a 10′ piece of rope and ride along a sidewalk or empty trail. Hold the rope loosely in your hand or you might get yanked off your bike.
A bit of advice, give them breaks, bring water and a bowl, and DONT GO DURING RUSH HOURS!! I made that mistake ONCE at Palmer park. Everyone hated me. I felt like a jerk.
