That is great news....I am so happy the doggie door has worked for you.  I have to say mine love the doggie door too.  
 
I do happen to have a small problem with mine though.  My two yorkies will not ever have a potty accident in the house when I am home - they will go outside all the times BUT if I leave them out while I am gone I will come home to puddles of pee on my tile floor even when they know they are to use the doggie door and it is open for them to go outside.   
Any suggestions or am I going to have to crate them their enitre life.
