I bought my bells from
Welcome To Poochie Bells. My Zoey rings it about 50/50 when downstairs, but when upstairs, she just swats! She also has accidents often when she gets a little free roam time to play rough with her big brothers.
This is my first Yorkie & I'm finding her WAYYYY harder to potty train than my 2 Maltese boys who are now 5. I also have a 1 yr old rescue Chihuahua who was already house trained. I'm really losing it! It's so exhausting and I wonder if she'll ever grow up to be an enjoyable pet like my boys.
