we just got a litter done for my daughter , only one vet in the practice we use would do them, and she keeps terriers herself. Only needed a letter of the poultry farmer i rat for to say i work my terrier. Chargaed me 20 quid per pup docked chipped and certificate checked all the pups and bitch when we were in she said she will do us a discount on vax if we want them done
