A Collaboration With Poi Dogs & Popoki (PDP)

HI Pets is proud to work with PDP, their board, and an army of dedicated volunteers. For 7 years, the animal welfare nonprofit has been operating The Big Fix, a mobile clinic providing affordable spay/neuter and wellness services to families in underserved and rural communities across the island of Oahu. Through this collaboration, HI Pets joins with PDP to service their network of rescue and adoptable ohana from Waianae to Waimanalo to Waialua.

PDP Cares Fund

We know how expensive veterinary care can be and we work hard to not only keep our fees affordable, but to provide pet owners with alternative solutions. So PDP has started the PDP Cares Fund to help pay for surgical costs for rescued animals as well as pets of qualified owners that cannot afford life saving treatment.  Tax-deductible contributions can be made at the clinic or online by clicking the donation button on PDP’s homepage: www.poidogsandpopoki.org.  Be sure to indicate that the donation is for the PDP Cares Fund.
