Not against and not for.
Not a dog owner and have only have had two experiences on rides with dogs on the trail
1st at Haughmond hill where the dog was a PITA weaving on and out stopping, causing crashes etc
And the folk that bought it along we’re not in the original group. They were surprise guests of a club rider
On the flip side, at the weekend my mate took his around Woburn with us
It knew the trails and where to go always running at the side of you about 2m to the side in the undergrowth
It was a pleasure and after about an hour the dog went home and we continued
Personally I don’t agree with dogs on trails at trail centres, but elsewhere live and let live
