Megan was only 3.4 lbs her whole adult life, she had a heart condition, sensitive skin, and her teeth were a constant problem. I think the smaller ones are more fragile, mainly due to bone size and density. Gina is almost 17 weeks and close to 3lbs now, her legs are thicker than Megan's were. Regardless, Yorkies of any size need to be watched out for, as well as any small breed. Megan needed to go out more frequently than Gina does, but Gina is doing better at potty training than Megan did. I still like the smaller sized Yorkies, but Gina will hopefully be my service dog, so a larger size is better in this instance. I hope your fur baby gets better soon, but for 15 years we had health issues with Megan, but it was a wonderful 15 years with her.
Cheers Quad
