So basically if its up to the vet its up to him what evidence he wants
You should ask your vet to be more specific.

Are you sure to send those pups to be working dogs and not pet?
Maybe if you have a list of buyers and they can say they want the pup for that purpose...dunno

Can i just ask; what is the point of a working dog having his tail docked (I assume there is a purpose since it is still accepted in law..although it seems to me that it is more tolerated than accepted as such)? just curious
