I will say yorkies or just small breeds seem to be the most difficult to train to hold it.
Like Brit said it depends on your circumstance, if you work at home like I do, it is much easier, I also believe that the leash method and using a bell to be the best in the long run, I will find the post where I explained what I did and still do and I have to say Lola is 100% house broken, none of my others were. My last was paper trained and went on his paper 98.5% of the time, but if something did not go his way he would wet in different spots, I swear just to pizz me off |
