I recently got a Jack Russell terrier. I was hoping he'd be a good running buddy, and he is great to run with off leash on private trails. However, it's nearly impossible to run with him while he's leashed. He's constantly either pulling or stopping to sniff things. He doesn't enjoy the simple act of running along side me, or even walking with me while constrained by a leash.
Anyone have success training a JRT/small terrier to jog while leashed?
