Our 4 year old lab is now reverting back to peeing in the house. Won't eat. Vet checked this week and NOTHING medically wrong. I'm at my witts end, can't have my carpets ruined. I'm back to having to crate her again after she's been out for 6 months. Nothing has changed in the house, no new animals, nothing. I have no idea what to do!
I think I'd want a fuller investigation at the vets or a second opinion, if a four year old dog starts behaving very differently (you have two symptoms after all - the weeing and not eating.) Did you give the vet a urine sample? What about blood tests? Is she spayed - if not could she be coming into season?
