Katherine has been an excellent sitter for my chocolate lab Buddy.; over the past year or two she's watched Buddy about once a week, and he is always so happy to see her in the mornings when she comes over. Buddy loves playing with Katherine out in the back yard and has a couple toys (one yellow tennis ball in particular) that he prefers to use with her over anyone else. We love Katherine, and our dog does too. Anyone thinking of using Katherine to sit their dogs should be well assured that she is an excellent caretaker, walker, and occasional mess-cleaner (Buddy has a habit of knocking over flowers). I would definitely recommend Katherine if you want to have a happy, healthy dog.
