Madi has cared for my elderly dog, a Chihuahua named Steve, several times over the past few years. If you know Chihuahuas, you know they aren't the sweetest at first and are very territorial. Madi was very patient with Steve and followed all instructions down to the last detail. She even took him on extra walks! She's cared for Steve several times overnight and for several days/overnights in a row while we were on vacation. She's always been very trustworthy and responsible when entering and exiting our home, making sure to lock up and handle all security instructions. I would recommend Madi in a second for any dog and cat sitting needs!
