When I was younger, we had a black lab named Maggie who loved roaming the farm land. My friend would always message me if I could watch his Golden Retriever if he goes out of town, which I have always said yes because he is a good boy! When my brother and his wife had their first born child, I took in my brother's dog Lemon. She uses the doggy door to let herself into the backyard that has a 6 foot privacy fence.
