[yorkiemini]

This is an ongoing issues with long hair.
When I sew for my Yorkie I line everything with "slickery" fabric and that helps. I also spray the coat with Vellus Static Stabilizer and sometime the inside of the jacket too - I love that stuff in the winter!(and under clothes).

A friend of mind slightly wets her hands and rubs them on her Yorkie before putting clothes on her.

I do admitmthT I tend to prefer clothes/coats thT I don't have to put over the head- have even converted some sweaters & tee shirts to velcro or snap closures to avoid it.

Good luck. Let us know if you come up with any other solutions.
