I have a long haired chihuahua who is 11 years old. There aren't to many people that I trust her with because she is getting older. But because Sheridan has experience with older dogs as well as pups I know that she will be able to pick up on worning signs if any. Missy loves Sheridan, you can feel the warmth she has for anamles and Missy can too. It's harder for Missy to go potty now that she's older so you have to have patients with her as it could take 25 min to get a poop. I only get good reports from Sheridan about Missy and that's important to me because I know how hard it could be to watch over Missy. Highly recommend her to sit and walk Missy when I can't.
