We had a thread awhile back about nails, specifically:
http://www.yorkietalk.com/forums/sho...clipping+nails
But for the other things, I have this stuff called Calming Aromatherapy Spritzer, which has chamomile and lavender in it... I'm watching my friend's Yorkie and used it on her to brush her out. Normally she tries to eat the brush! but when I used the spritzer, she actually layed down and even let me brush the hairs around her face!!!
My 3 month old, Roxy, wasn't as receptive
Hope that helps!
