It's not difficult to groom yourself your own yorkie.She or he is more costumed with you as with other ppl,so you can ask to stay till you are cutting the nails,the hairtips and the hair of the hear.Also you can much easyer clean the hair from inside the ears as well.
Maybe the first...second time ,it will not come out how you wish,but doing it often,will be better and better.
Do not have to forget that" Exercise is doing the master!"
Ps.It's something else with the showyorkies....but do not ever forget:
Noone was born to know everything from the start,we can learn many things,if we want.
