Big dogs are not a problem to walk, I don't get pulled around too easy. I am flexible on the length walk your dog prefers, and am willing to alter the length and route based on how your k 9 friend is feeling. I love energetic and Good natured dogs, as well as happy, and calm dogs. I don't mind their bark, as long as they do not bite. Most weekdays I have plenty of time, and most Sundays. I am at work most Saturdays. Leave instructions and any relevant cleaning chemicals if the dog is prone to leaving messes. Instructions on where the dog food and leash are kept will also be helpful. Any dietary restrictions for the dogs should be noted as well.
