Previously House Broken Dog Has Started Pooping in the House

My 3 year old racing Greyhound cross Alsation has in the first week peed on my bed and then 2 days ago she has pooped on my bed? Would you know why and how do I combat this? She is full trained. Please help.

Have you sprayed the affected areas with vinegar? Maybe you can go back a step and restart praising and giving a treat to the dog when she does her business outside. (12/08/2009)

Please take her to the vet. Rarely do animals change their behavior for no reason. (12/10/2009)
