Dede finds these shirts helpful for anxieties. Nothing is guaranteed for all situations. But, she's carried this brand for over 5 years and no complaints. Size is important. As we do not do refunds. Saki, on her Youtube channel wears a size small and Faith, her min pin mix dog wears a medium and Brownie wears a medium if that helps. Nothing fits perfectly. But, it fits really well on all pets. It's the snugness that Dede agrees, helps fight the anxieties of thunderstorms and rain storms, and high anxiety pets. Try one today. Thank you for supporting us. This listing is for the green version.
