I totally agree - Izzy is almost 10 mos old and although she is about 90% potty trained we still have accidents but those accidents are far and few between and usually because we are not watching her or in her case she rings that darn bell to often..hahaha....don't know if she wants out to potty or go on squirrel patrol.
I'm also a believer that training is an everyday thing...you never stop training your dog no matter how old they are!!!
