Don't feel like a failure. Bentley is a year old and just recently has gotten much better. He still has the occasional accident. Yorkies are very difficult to potty train. Bentley lets me know he has to go by standing at the door. Then I ask him if he needs to go potty and he starts ddoing little circles. I call it his potty dance. How old is Ozzy? When he goes outside make a huge deal of it. Clapping and praising and treats. If he's young take him out every hour or so. We tried crate training to potty train but it didn't work for us. Make sure you clean his accidents with something made to get the enzymes out so he won't smell it and think he can go there again. It just takes time. Lots of time and patience. Don't be hard on yourself. We have all gone through it with our little ones.
