Peekage is offering free Miracle Guard Dog Pads by Hartz. In order to see if you qualify for these, answer a few questions which should only take a few minutes. They're basically looking for people with dogs, duh.
If and once approved, you can expect your freebies to test out in 6-8 weeks. However, I've found that previous Peekage samples arrive within 4-6 weeks, so just tell your pup to hold their bladder for a quick month.
