When choosing a leash for your dog, you'll want to consider size, weight, and temperament. Whatever type of leashes you go with, make sure they are suited for the right sized and weight doggy.
If you're looking for a leash that has many practical features but is not too overwhelming, consider a retractable or extendable. Dog leash come in a variety of lengths, depending on what your needs are, like the need to walk further away from your little guy without constantly pulling on the lead. Some leashes even come with brakes that prevent your pet from running off at high speed.
If your dog tends to get out of control quickly, consider getting an iron grip leash instead of a retractable or extendable one. These types of leashes are made from durable materials such as metal or plastic and are difficult to break free from your pet's grasp. If this type isn't suitable for you, you might want to consider a harness instead.
