Sabrina, many thanks for your offer of help. I have been in touch with the lady who has asked the question, and passed your details onto her. Have been tied up with vets, foster cats, dentist and taking Gold Kennel Club Test last night. We so nearly passed but my dog sat up from her "down" to see where I was in the out of sight bit! Oh and we have our oldest son in a hospital in Tokyo with head injury, so been trying to find out more about him.
So you should be hearing from someone soon, fingers crossed. Once again, thanks everyone for the help, I do appreciate it.
