Hi guys!
After reading all your comments, I decided I would not be going to that breeder! And boy am I glad...
Instead found another advert...
Male Yorkshire Terrier Puppy for sale in Cardiff on Freeads Classifieds - Yorkshire Terrier classifieds
Today I went & met the family (the EIGHT puppy litter was an accident) who were very nice & I placed down a £20 deposit. I should be picking him up Sunday! The family told me that I could take him back at any time as they have grown very attached & its important for him to go to a great home.
Any opinions would be appreciated!
