I just had Bonzo at the vets for his boosters.
The vet had a listen in to heart and lungs and tells me he's as fit as can be; more than probably due to running with bikes as she knows that's what we do. Low heart rate at rest just like his boss 🙂
He loves his bike rides and is pretty well behaved, except he did a lap and a half of the red/black at Drumlanrig t'other week with a bunch of mtbers (and their dogs) while I was out coaching the sproggs. Cheeky monkey didn't even ask if he could go play.
Returned him later with glowing reports and suggestions of flouro jacket and hiring him out as a 'trail 'guide dog as he knew the way round so well.
