We got Autumn from Denise Dennis at Serendipity. We asked for a girl boxer and fell in love with the first pic. She sent pics regularly and ended up meeting with Denise and Autumn (now Lucy) at Quinn's Hotsprings to drop her off. Lucy came with a LARGE goody bag with toys and treats, her file with her shot history and pertinent information. The whole experience was wonderful and Lucy is everything we wanted.

Denise at Serendipiy’s was absolutely great to deal with. Very responsive and followed thru on everything! That’s getting to be a rarity now days. As far as the boxer puppy, we couldn’t be more happy. We’ve had boxers for about 35 years and they are hands down our favorite. We’ve had some exceptional boxers and the puppy we got from Serendipity has all of the very best traits. I would recommend Serendipity to anyone, hands down!
