Laura's Lost Pet Services

Laura’s #GivingTuesday Fundraiser for Laura’s Lost Pet Services, Inc.

Giving Tuesday has come to follow Black Friday and Cyber Monday. It is a chance to return to our Thankful celebration of what we have by helping others. This year, I am helping my friend Laura Weitner. Laura is raising funds for her non-profit lost pet finding service. Laura has her own pets, a job, and family. Every day though she helps people in her community find their lost animals. She does this out of kindness and love of animals. She also helps capture and rehabilitate the homeless ‘neighborhood dogs’ of West Virginia. This work often involves long nights waiting for a dog to enter a humane trap and potential bites.
