I have a Westie, but it is a Male and only 9 months old. There is a forum for Westie owners like this one, but not as active. The web address is:
www.crazyaboutwesties.com I don't know if anyone there can help you. I know my breeder has a website, but I don't remember what it is. I will try to find it. I didn't meet her. My daughter and I bought Duffy for my husband for Father's day and my daughter met the breeder and bought him. It was two ladies who were breeders. I have the information at home.
Westies are great little dogs. Is your friend going to sell them? They don't bring quite as much as Yorkies in this part of the country, but almost. My daughter and I gave more than they normally sell for, but the breeder was excellent and had good dogs.
