Tolin

Canines for Christ Therapy Dog

Tolin is a certified therapy dog through Canines for Christ Therapy Dog Ministries. Tolin is a German Short-haired Pointer/Beagle Mix and was hand-picked at 9 weeks old to be trained as a service dog for a military veteran. She excelled at her training and would have made an excellent service dog, but was unable to be teamed up with her intended match. Tolin came to live with Pastor Matt & Beth Overman and their family in January of 2020. She has become an important part of their family and in the ministry at Grand Lake Church. You will normally find Tolin in the kid's hall on Sunday Mornings and Wednesday Nights. She is also excited to be out in the community visiting schools, nursing homes, the library, and other places. If you feel called to the ministry of pet therapy, please contact Pastor Matt.
