How to make a crate divider
Choose a crate suitable for your dog.
To ensure that you're getting the right size, pick out a crate with your puppy's specific breed in mind. The idea is to start off with a crate large enough for your dog to grow into.
As they get bigger, you'll gradually move the divider to increase the size of their sleeping area. If you own a labrador puppy, for example, you'll want to get a crate that can accommodate a full-grown lab.
