Doc, a purebred male Border Collie, was owner-surrendered to the Arlington Shelter with an Aussie due to “moving”. Considered a senior, Doc is still in great shape and does not show any sign of age. A very sweet dog, he currently looks to his people for support but is getting more and more independent. He likes playing with other dogs though he does prefer his person, and loves to run outside and chase squirrels. Doc would be great for a urban or suburban household looking for a mature Border Collie who comes already house and manner trained.
