Hello and welcome!
Sorry, I don't really understand what you mean by tiring her in her crate??
The way we tire Harry out is to give him a really good walk, then lots of running and play around the house....he's normally exhausted by bed-time and then sleeps through from about 9 p.m. to whenever we wake him up.
Do your Yorkies all play and have a good game together? Sally + Harry
