I owned a French Mastiff and Boxer myself. i walked my dogs everyday. I have been dog walking/sitting for about 8 years. I can do light grooming/bathing if the dogs are small. Dogs wait all day for us to get home, so for me to give them that 30 minute walk or some play time makes my day because they do nothing but wait for us. I love all types of dogs, big or small so size is no problem for me. I love going on walks with the dogs, not only do i get to exercise but i get some time to play with the dog and keep them fit and healthy as well. I cant wait to walk your dog ! Hope i'm the right dog walker for you!!
