Maggie and Molly are 15 weeks old now. They seem to be progressing at a good pace. Still working on potty training! There are days we think they have it and then - a suprise! They are doing very well with the come command, sit and we are still working on stay but we are making progress. Molly has developed a habit of biting rather hard and we are working on stopping that behavior. I guess that is the life of Yorkie parents!!
