It's Dress Up Your Pet Day tomorrow, and we thought it would be fun to collect people's photos to celebrate.

The day was set up by celebrity pet expert Colleen Paige in 2009, to be on January 14 every year, so let's give its ninth anniversary a good go.

Whether you have a Jurassic Pug or a caveman cat, or something weirder or more exotic, we can't wait to see them.

We will put together a gallery of all the submissions tomorrow, so be sure to send yours in or check back tomorrow to have a look.

Please make sure any photo sent to us has permission from the copyright holder (usually the person who took the photo) for us to publish it.

Send them by 4pm tomorrow (Sunday, January 14) to
