I am a 78 year old who is very fit. I work out at crossfit three to four days a week. I have grown up with dogs all my life In that time frame I have had every size dog you can imagine. When I lived in Poughkeepsie we dog sat for seven years, when we came to Raleigh we had to stop because of my wife's illnesses. Since she has passed I have started the service all over again. I love dogs and I most cases they love me. My house is all on one floor,this is grate for older dogs and for handicapped dogs. Because my wife was handicapped my back door has a ramp therefore no steps.. come and check me out. Bob
