Hello, my name is Mac, and I am a young tan and white mastiff mix boy. I was born at the end of 2015, and I weigh about 65 to 70 pounds. I was left behind when my humans moved away, and Desert Haven rescued me from the animal shelter at the end of 2016. I am young and energetic, and also sweet and well-behaved. I love to play with all my human and furry friends. I enjoy being petted and touched. My greatest joy is to have one of my human friends rub my tummy! I thrive on human interaction and like lots of attention. I chase rabbits and cats, so I would do best in a home without them. I would be a loyal companion, either as the only dog or with other dogs (ideally female or non-dominant male), in the right forever home.
