So since we have been biking with Teagan, who is doing really well with it. I think we need to buy a specific harness for her while biking. She likes to pull for a while while we are biking, which we have no issue with. She really enjoys it, but because of that I wanted to buy a specific harness that supports her while she is pulling, but I have no idea where to start. Linds, already gave me a great option, but I want to see what else is out there and what you guys use while biking with your dogs, especially if they pull.
