Okay so my yorkie poo was on an 8 week vacation to my parents how while my family was away for the summer. She did not have one accident in the house. The day she came home already she spot peed on the carpet in our playroom. The only conclusion I can draw from this is that there must be pee in the carpet and she is drawn there to mark her spot or thinks she needs to go there. Then the second conclusion I draw is that there must be several other areas in the house that have pee dried up. I know there are products like Scoe 10x or Natures Miricle but how can I be sure that all of the pee in the entire house carpets are gone? Will professional cleaning do the trick? any other tips on this?
