I just got a Westie. She's five months old now. Westies are known to have skin issues so you'll want to be sure about the breeder's previous liters with regard to skin issues. Westies also have much, much more energy then any yorkie I've ever met! My puppy Westie is absolutely crazy! She came to us crazy at 9 weeks and has stayed crazy. She never quits!
Westies are very smart. Often, too smart for their own good! They are a lovely breed though and tons of fun!
