Because dogs are active animals, it's not good for their health to keep them locked up for long. They need their exercise in the outdoors. At the same time, though, it's perfectly understandable why you want to control your dogs' behavior. Some dogs, when left on their own, can cause a lot of damage to your lawn or backyard. Some even jump over fences and run away!
The Four Paws Pet Products 75-Feet Cable Trolley from Pet Store provides the perfect compromise. One end of this cable is be attached to an overhead trolley cutting across an open outdoor space, and another end is attached to a tethering fixture around the dog's neck. Because the cable is long, and because the overhead trolley is connected to the cable via a pulley system, your dogs can still roam freely around the open space. The length of the cable will limit them from reaching areas you don't want them to go to -- particularly the fence, if they're jumpers.
The Four Paws Pet Products 75-Feet Cable Trolley are best to use with dogs weighing over 50 pounds. It is safe and strong enough even for such big canines. It is also waterproof, so it won't rust even when exposed to the elements.
Four Paws Trolley Exercisers are available in three break strengths and two colors red and silver. They are available in lengths of 50', 75'and 100'. All Super Trolleys are available in 25 and 50 feet lengths.
