hi thanks for your replies, i have a patterdale terrier. when i breed her most of her pups will be goin to working homes as i have a few people wanting one. il have to wait and see how many she has first before i start telling people theres no pups left. i asked my vet if i could get a letter off the farmer i have permissin off and they said that isnt evidence that they will be workers. in my eyes all patterdale terriers are born workers and not really pet material. so if anyone can give me any idea what other form of evidence i could use its more than welcome
