Yorkies have a thing about their feet - I don't know why, but they're freakin drama queens about their feet and especially their nails.
I used to wrap my 2 in a towel like a mummy - holding one foot out ..do that foot - take a little break - then next foot -now I pretty much can sit and talk to them while I clip... but it took 6 years to get to this point
Try to keep those nails as short as you can - one day you may not be there if she gets caught ...and the other reason is the 'quick' will be longer if the nails aren't trimmed on a regular basis - AND - it can hurt them when walking I would think too
You did good ....if you really have problems - some vets only charge 5-10 bucks for nail trimming and many will do it if you ask for free on routine visits etc.
