What’s up? I have a Pitbull ”Harry” I upload one of his photos I love him so much,,,we go for a run together every day after I get at home. Harry is only one and a half year and is very energetic and strong. I’m really into the idea of going for a ride on my bike while Harry runs near me and I’d like to know if there is any kind of dog collar and leash for doing this more comfortable. Thanks in advance LOL!
