I have had Kelsey watch both of my dogs several times in the past, and have seen her work with several dogs at once. My Yorkie, Twix, can be a bit of a handful at times (separation anxiety, scared of new people, etc.), but Kelsey was able to quickly create trust within him and was able to keep up with his bathroom and food schedule. Kelsey cared for my senior dog, Jerry, and helped with his dental and heart issues by providing medication in his final days. I have also seen Kelsey work with three dogs at once, two small, one large, and was able to give them all the attention they needed (the large dog is a puppy and very rowdy). Kelsey also owns and cares for two cats.
