As Dan mentioned earlier, dogs require a lot of time that cats don't. They are more playful and loyal than cats, but you either have to take them with you or return home every few hours to let them do their thing.
Here's Sophie! She's a good pup. We think she's about 4. Yellow lab. Very friendly, unless your the mail carrier. Rescued from a violent home. Sad what people do to critters. She's part of the family. Recently went to the lake where she swam and chased ducks and had a blast.
