Yorkshire Terrier Training

Yorkshire Terrier Training!! tipss n helpp plzz?
Ok since we went on vacation for 2 DAYS ONLY! my dog was left with my moms friend. Came back with her and she forgot EVERYTHING except bad things such as bite me and eat something she shouldn’t.
And i used to have a book that taught me how to train her but i lost it.
So what were the basic training things??
And any tips on Potty Training
I have a good book on training your dog. First some of the ways to stop your dog from bitting you is every time she tries to nip at you, say “bad”. That will make him relize that he did something wrong. Also if she bites other things like lets say your cabonints of like your table, their are these sprays that you can spray on things that dosnt stain or smell, but when the dogs go up to it it will only smell for them. Know for potty training you have to have the potty in one spot so she always knows where it is and also try to bring her to it the first time and everytime bring her to it and eventuly she would get used to it. thats the main way. But once her sent is their and her territory, she schould always go their. Hope this helped.
