Trying to find the appropriate size for a 25 pound dog. Only available sizes are small or large- not sure how big they are. Suggestions please...

Do the two different sizes have different size openings and can fit siffeeent size treats? The denta stick is extremely hard to get into the small.

is this better then the kong? My dog takes 10 minutes to get the treat from the kong

Does the larger size toy have a larger hole? Bully sticks seem to get stuck in the smaller size. Thank you!
