So having calmed down and talked to another mate who was with Dave when it happened. Turns out I was wrong about the lead, it wasn't the one I have had words with him about.
But one his granddaughter bought, apparently from poundland type shop with her pocket money at the weekend.
So I have just eaten humble pie and apologised to him.
His reply of don't worry I know your heart was in the right place.
Made me feel a bigger cuñt than I already did.
I also went to the corner shop and watched the cctv.
I think she was killed instantly, hit by a van and knocked into opposite lane and squashed flat by a bigger van.
Guy in the shop formatted the hdd to erase it after I watched it.
He was a star and covered her up.
Got her body into a box and drove Dave home.
15 minutes after that was when he knocked on my door and I reacted like a cùnt.
Don't want anyone going away thinking hes a cùnt.
He doesn't know how to tell his granddaughter, I have advised not mentioning the lead to her.
Such sad news, especially as it was avoidable. I think you’re right to be furious with him, he did not protect Clover by spending a few pounds on a good lead and now she is dead. You deserve a lot of credit, you did more to try to protect her than her owners ever did. His granddaughter’s gift was kind but we owe it to our pets to protect them - and he failed, big time.
