Did you know August 1 is DOGust, the universal birthday of shelter dogs? DOGust was started by the North Shore Animal League America in 2008 to give shelter pets some much-deserved recognition, as many have unknown histories and birthdays. Now, adoptive pet parents have a day to celebrate their pets’ birthdays!

This year, we’re celebrating DOGust all month with a sweepstakes for adoptive pet parents and their shelters and rescues. The sweepstakes is open to entries now until August 30, 2015, at 11:59 p.m. ET. To enter, visit the contest page here, fill out the entry form and share a photo of your adopted pet. We also invite you to share your pet’s adoption story with us!

Five winners will be randomly chosen on August 31 and will win pet birthday packages. Each birthday package will have:

• A $75 gift card towards a 1-800-PetMeds order
• A 1-800-PetMeds Max or Molly pet toy
• 1-800-PetMeds branded pet products

The packages will be tailored towards cats or dogs, depending on the type of pet.

The five winners will also win free flea prevention for the shelters and rescues they adopted from! Each rescue group will receive 100 Advantage II and/or K9 Advantix II adoption kits. The kits contain free doses of flea prevention, and sizes will be tailored for each rescue group.

The sweepstakes is open to U.S. residents 18 and older (void where prohibited) with an adopted cat or dog. Shelters and/or rescues must be U.S.-based to qualify to win.

So what are you waiting for? Share your pet’s adoption story with us and enter the PetMeds Cares DOGust Birthday Sweepstakes now for a chance to win for your pet and rescue group.
