I have experience with large breeds. The dog in the picture is my extra large Shiloh shepherd who I have no problems walking. I can walk any sized dog ranging from multese to kangal! Pulling on the leash is no problem and I can take that aswell. You can pick how long and which path I take if you so choose. If you want your dog walked on a nature trail the price would be 25 an hour instead (: my name is adi and my cell is 9054625745
