Oh my gosh. I can't imagine, especially since we have had our pup for only 6 days. My heartfelt sympathies go out to you and your family.
This almost has to be environmental. Where is she going potty?
She was going inside the house (was trying to potty train her) and when we caught her in the act we took her into the back garden on the patio where she had her own little 'doggy exercise area.' We didn't allow her to go on the grass incase she ate any of the fox poo.
