Why is my puppy experiencing crate regression and how can I address this behavior effectively?

Crate regression in puppies can happen due to various reasons such as anxiety, discomfort, or lack of proper training. To address this behavior effectively, you can try making the crate more inviting with treats and toys, gradually increasing crate time, and providing positive reinforcement when your puppy is calm in the crate. Consistency and patience are key in helping your puppy feel comfortable and secure in their crate.
