Crates are the cornerstone of any successful housetraining program. Crates are for every size puppy or dog. Following are a selection of crates in the Life Stages line which come with free dividers so you can expand the space as your dog grows. This enables you to use the crate for crate training and housetraining and then continue to use the crate as your dog's home for life! PLEASE NOTE: A rule of thumb about size if you're using the crate for housetraining: the crate should only be big enough for the dog to comfortably stand up and turn around in. You don't want the crate so big that the dog will mess at one end and sleep at the other. That's why the Life Stages crates are perfect because you can expand the size according to where your dog is in the housetraining process. For our free housetraining report, please click here. PLEASE NOTE: All the crates on this page are collapsible and require no tools to assemble. Just unfold and you're ready to go!
