I would follow your dog's pace, if he or she wants to run, I'm willing to do it and if they just want to walk casually I'm for it. I'm make sure the end of the day that your pet is happy with their walks. I usually wait till they finish their business before their walk ends. I have taken care of dog for 3 years. My whole life I have been surrounded with dogs. I'm very patient and I love dogs. Some experience about dogs is during the summer helped my neighbors by walking their dogs while they are working and also bath them after. I currently have one small morkie, he's three years old. I'm willing to walk your pet when its raining or snowing.
