I have a 4 month old Yorkie-Poo and he is the sweetest thing you have ever met so I do not think the breed is aggresive at all. You really need to take her out every hour on the hour. It has only been 4 days,,,give it time. When she does go outside praise, praise, and more praise, maybe even a treat. I am very fortunate with Scooter,,,,he is already house broken but on the other hand I am having a very hard time with Sadie, my 8 month old Silky. I just keep working with her and I know in time we will get it. Good luck |
