I have two standard poodles. I bought matching outfits in different colors. I cut the tags off and tried them on, but they were too big. It might also be because I had them groomed at the end of the year, so they're thinner now. I think these are for dogs bigger than standard poodles. Length (back): Approximately 59cm Chest (laid flat): Approximately 45cm They have a zipper, so they should be easy to put on.
