Hello! Congratulations on your new puppy & welcome to YT
Even my very small crate came with a dividing panel to make the inside of the crate even smaller. Did the intermediate crate come with this extra panel? I believe if you are crating to aid with potty training, you want to make the inside of the crate only large enough for your pup to just stand up & turn around in. Any larger & they may sleep at one end & pee/poop at the other. The goal of crate traing is to use a pups natural inclination to not want to relieve themselves where they sleep. Larger crates give them too much space & defeat this purpose.
