I get mine (and Mum) checked the morning after birth at home, then get thepups checked at the vets at around 7 weeks before they go to their new homes, so I can check if testes have dropped etc by then, (They can be VERY difficult to feel in tiny pups, and I'm not always 100% sure!) as well as everything else is OK.

Edited to say I think call out fro MUm and pups is about £70 ish, and vet check my (expensive!) vet charge at half the normla consult fee, which is £15 per pup!
