Hi everyone! Im new to this site! Its so exciting to see so many people as crazy about their yorkies as I am! My breeder recently contacted me and said that my yorkie's (Pasta) mom had another litter. My husband and I have been considering getting another yorkie. Pasta is now 1.5 years old and male. He is so well behaved and mellow that one of our conerns is that getting another dog could "change" him. Any thoughts?
