Rubie'sRubie's Disney: Winnie the Pooh Pet Costume, Eeyore, Small

I have a 26lbs beagle. What size would fit him?

Is there a size chart? I have 2 mini schnauzers but one is a bit bigger, I'd like to measure them to make sure the costumes will fit.

I have a 10 pound doggie measuring between a extra small and small. Which soze should I get?
