I have always owned dogs and been a "dog" guy! I love fitness and can handle any size dog - not just little ones - you have a Mastiff, no problemo! Run your needs by me - we might be able to work something out. At my house? Ok! Your house? Ok let's set up a time to talk and figure out if we are a good fit. My wife who is also works on rover and I love fostering pups while their owners are away. Our house is located in High Ridge Mo and backs to a beautiful wooded setting. Our yard is fenced with 5'chain link fencing and has 2" rock all around the base so no escapes happening here so no worries. At your place? No problem! Let me know your pets needs and we can make it work.
