I'm sorry. All I can say is to have patience and more patience.
(This coming from someone who is also having problems with potty training)
I just don't have an answer for you. The 2 yorkies I had before Abby, were potty trained with no problem and once they were trained there were no messes in the house. Now with Abby it's a different story. I can't get her to stop messing in her crate at night
I'm hoping one day she will finally get it.
Tonight she didn't tell me soon enough that she had to go out and she pooped on the floor.
It seemed like it came up on her very quickly and she just couldn't hold it. Sometimes I am at my wits end and then she will have a few good nights, then she regresses
Oh by the way, Abby will be
9 months old tomorrow so she is 5 months older than yours. I have read from many posts here that Yorkies are difficult to potty train. I really didn't know that until I got Abby. She is so totally different than the other 2 I had.
I wish you good luck and hope your little one will finally "get it" soon.
