This pertains to Ziva the min pin but Zoey has issues with it sometimes too. At work they are kept in a large exercise pen, they have 3 beds (1 large dog pillow) and 2 smaller beds, they have water & a potty pad in there. Ziva will pee on the big pillow, I wash it everytime. She uses the potty pad as well. Zoey likes to pee on the bathroom rugs at home. Is there anyway to help them 'differentiate' not to pee on the material? Or is potty pad training kind of defeating that purpose and maybe I need to move to litter box or the indoor grass potties? It gets frustrating having to wash a large pillow every day, I also have tried pulling the pillow out and just leaving a blanket in there, and she will pee on the blanket too.
