Full disclosure, Katerina in our Grand Daughter. She lived with us as she went to college. When she joined us we had two rescued Greyhounds. Katerina cared for the dogs when we were at work or out of town. She also cared for some of our neighbor's dogs when needed. After our last Greyhound died she adopted her current dog, Millie. Millie was just a puppy when she came home and Katerina proved to be a caring, patient and accomplished trainer. By the time they left Millie was leash trained, house trained, sat on command, stayed and/or came when told and could be trusted to stay of leash in our unfenced front yard while someone worked in the yard. Katerina loves animals and any dog that I've seen her meet senses that almost immediately.
