Well I have a Yorkshire Terrier so I'm a little biased! lol The breed is 4 to 7 pounds but there are some a little bigger and some a little bit smaller. They don't have fur, they have hair so when you brush them a little comes out in the brush like your own hair but they don't shed. They have great personalities, they're very friendly and great little lap dogs. I was at Westminster this week and got to see all the wonderful dogs and talk to the breeders. The Cavelier King Charles Spaniels are adorable but you have to check going back to their grandparents to make sure they have no heart problems. That's a problem with the breed. I watched them pick the long haired Chihuahua that went into the show in the evening. Boy were they cute. I also watched the Maltese, Papillions, Yorkies, Chihuahuas, ShihTsu and some of the other small breeds. Boy I'd love to take all of them home. Well good luck in picking and let us know what you decide.
