I have one of each - my Porky Yorkie, Spanky at 6.6 lbs and my little 5 month old Mango at 2.8 lbs (at her last vet visit). I definitely worry about Mango's petite little bones. Spanky is so much more chubby and solid than my little one. She has always had the greates appetite, while Mango is the pickiest eater I have ever seen. I LOVE both my girls to smithereens......
