Five month old wheaten was spayed ten days ago and is now peeing and pooping in house even if she has been out for thirty min. help?

I doubt the procedure caused her to start soiling in the home.

The constant needing to urinate could be related to a UTI.

Has there been any changes in your home? Did you change the potty spot?

If this continues and/or gets worse, you'll need to take your dog in for a check up. You're getting close to a 14 day recheck post spay, bring these issues up with your vet.
