A sad loss Stuntman, all the best with his pups, I hope they work well for you,, but I wish you were right Skycat.. when I was a single handed keeper in Northumberland, early 1 season we lost 2 dogs off the same hill from adder bites. The first was a Labrador, a big strong one at that, I was taken to the vet that day where it was tret. 2 days later it was dead in the kennel, vet reckoned liver/kidney failure. Second was a farm sheepdog out gatherin the hill, dead by evening with swollen bite to throat.
All the best
