Believed to be a Saint Bernard/Retriever mix, Marty was rescued from a high kill shelter after the owner registered on his microchip failed to claim him after being picked up as a stray. He is 7 years old and enjoys kids and water! He can be very dominant with other large male dogs, but seems to get along fine with smaller, submissive dogs. He has some hip issues, so making sure that he has regular walks (not too long) and limiting play time is essential to Marty so he doesn't over-do. He is on an over-the-counter supplement for his hips at this time, but may, in the future, require prescription medication to help him live more comfortably.ght.
