Karen has been taking care of my Tux ever since we got him last august. She has even watched my other dog Meatball. She was great with Meatball during the time that he was still with us and is terrific with Tux. She treats him like her own! She takes Tux on walks, plays with him, and will take him to our local dog park. Occasionally, I'll ask to see if she is available to watch Tux while I am out of town. He does great with her. She lets me know if he needs to be taken to his vet while I'm away, and sometimes even takes him for me. She knows how to administer his medicine and makes sure he doesn't eat anything bad for him. We have him on a special skin diet and she knows what he can and can't have to snack on. I've even recommended her to my close friends! Karen is great!
