What kind of pads are you using?? It may be the pads themselves... We went through some of the pricey brands that macy just tinkled right through
We now put a a piece of vinyl under the whole area where her pad is, plus about 2 inches on each side... It helps if they leak, or if she misses
And yes, my macy wont use her pad again if there are more than 3 tinkles on it. She will use my floor instead...
