I use diapers on Holly only at night. The first time she peed and pooped in them was the last time she did that. She has been dry ever since. She did not like having dirty panties one bit. If you are going to use the diapers during the day, I suggest you order some cloth ones with velcro closures. The paper ones just don't stay on well at all. I ordered mine from
Senior Pet Products, The world's largest source of products and information for aging dogs and cats.
They might seem costly at first, but one diaper will cost you the same as a couple small packages of the disposable ones, and, they stay on much better.
