Dogs that hide or want to be left alone usually don't feel well. Given her recent potty habits that's no doubt. I would take her to the Vet, it sounds like she wants to be left alone but yet wants to play outside but something is stopping her. I know my yorkie likes tuna but I seldom give it to her. Tuna I know is not good for cats
