I have dog and cat sat (not sitting on a cat or dog!) for many types of breeds, most interesting time was for a great dane named Smokie who ate more in a day than I did! Availability can vary as I coach at Vassar, but have no problems with early mornings or late evenings. I enjoy taking care of all cats or dogs, other animals as well (not afraid of snakes). I have a very high energy yorkie, so am used to "crazy" dogs, as he often does not sleep more than 5 hours per night, so I understand trying to get some energy out of your dog. Communication is very important to me, please make your expectations clear and we will be good to go!
