I oten question my dad about my dogs ability as he much more experinced than me.
I rang him earlier to ask if he thought an adult dog would 'get' running alongside a bike as easily as my puppy did. I cannot let him off lead yet as he has no recall, so I thought this would be a good way for him to have a run and burn off some energy.
My dad said I shouldn't be doing it anyway, because it's illegal and I'll be fined if the park warden sees me.
I wouldn't be letting him off leash. I used to attach the pups lead to the handle bars of the bike, although she would have followed me anyway. And I wouldn't be going very fast. I'd take my cues from him and have run alongside/slightly ahead rather than dragging him along. But with my current fitness vs his speed, he'd probably be dragging me along
