Before purchasing, please review full plan information and answers to commonly asked questions available here. Available to U.S. consumers only, the Sassy Woof's Puppy Growth Pawtection Plan or PGPP, is an industry-first program designed to put your mind at ease if you have any concerns about your fur-baby outgrowing a harness (reversible or adjustable) or collar bought from Sassy Woof. Please note that only our reversible and adjustable harnesses and collars are PGPP-eligible. Strap Harnesses do not qualify for the PGPP at this moment. This plan will allow you to replace an eligible harness or collar for a bigger one within 9 months due to the natural growth of your puppy!* Harnesses and collars exchanged during this program will be donated to  animal charities/non-profits prolonging the lifetime and usefulness of our products! Harnesses: $12.99 per harness Collars: $7.99 per collar You are responsible for shipping the item to be replaced back to Sassy Woof. When received, Sassy Woof will ship the larger item to you at no additional cost using First-Class mail. *Sassy Woof will replace the reversible or adjustable harness or collar only once. The plan will then be considered fulfilled and no other exchanges/returns will be accepted.
