Remember, Yorkies and Maltese have tiny delicate necks. I really like a harness for young pups ESPECIALLY if you have children in the home. The harness puts the pressure on the chest---not the throat. The online pet stores have adorable and innovative ideas for harness/leads etc. Look at just these two examples of little harnesses (yes, the dress has a ring on the back for the leash!). Both of these are available at www.sassypup.net. They also have adorable styles for little boy Yorkies and Maltese.
