I have experience with dogs of all sizes and aggressions. I am very active and would love to go for runs or long hikes with your best friend! I have lived in San Francisco for about a year now and have been lucky enough to explore a wide variety of dog parks and dog friendly hikes. I have a 60-pound retriever mix who is very friendly, loves to play and also knows when it is time to relax. I enjoy teaching dogs new tricks including rolling over, off leash voice command, potty training and preventing pulling. I am a 6’3’’, 175 lbs male that would have no issue walking and caring for your large breed dogs. Let me know what your dog sitting needs are so we can work something out.
