Shelter Building Campaign.

We are making great progress on our property that we purchased in January 2015! Since acquiring the property between Belfair and Allyn on North Mason School Road, we have had many of our designs and applications approved including the septic/sewage system design, power application, and well site inspection. In May this year, our well was dug and the pump installed. We have also sent out our water samples and will next be installing our septic and sewer system thanks to the generous donations made from our Fund A Need at the 8th annual Sails 'n Tails auction.

The shelter will be built in stages as we want to have a shelter that will benefit the community for years to come, including the ability to house 30 dogs and 30 cats until forever homes can be found for them. As the land is a nice level plot, we will also plan for walking trails throughout our five acres for shelter dog walking and community events.

We continue to look for a gently used manufactured building that will allow us to move our offices from Allyn. And we always welcome any volunteers interested in helping us raise funds or contribute building expertise toward this goal.
