DDog is nearly 12 and was spayed alwhen she was about 6 months old. All of a sudden she has started to leave wet patches when she’s asleep. It’s not all the time but has happened on the sofa a few times now. She’s always been perfectly house trained so I’m assuming this is maybe an age thing. I’ll get her checked at the Vets asap but just want some reassurance that there’s a solution.
