Youth Work Party

If you are ten years or older, you can join the Youth Work Party Team with a parent to work on different projects around PAWS in Lynnwood, WA. For example, you can build boxes for frightened, injured wildlife to hide in. Ask your parent to sign up to join a work party. If you are eighteen years or older, you can join the Youth Work Party Team independently.

PAWSwalk

PAWSwalk is our biggest fundraising(筹款)event of the year, held at the end of the summer to raise money to care for the animals. You can collect money with the help of your family, friends and school, and then walk in the event.

Cookie Sale

Selling homemade dog cookies is a wonderful way to help the animals. PAWS can provide brochures(小册子)to give out when you sell the cookies prepared by you and your parents, so people can learn about PAWS at the same time. You can find homemade dog cookie cooking instructions on the Internet or by checking out cookbooks for dogs at the library.

Movie Night

Invite friends, family, neighbors and classmates to watch your favorite animal movie, like Babe or Charlotte’s Web. Ask them to bring an “entrance fee” of donations or supplies for the animals.
