Red is a senior who is around 10 years old. He weighs 52 pounds. He is good with people and kids but does like to nibble at your fingers if he thinks you have food. He is medium energy. He is good od with other dogs as long as there is no food involved. He is heartworm positive but due to his age we elected to do the slow kill method which isn't as harsh on his old body. He will stay on meds the remainder of his life.
