There are a lot of products on the market designed to stop a dog from barking while they're in a fenced-in yard and most of them probably work quite well except for the fact they tend to be quite expensive. Since most of the time the dog is just curious as to who or what is on the other side of the fence why not just let them see?The PetPeek is a 10-inch clear plastic dome that's designed to be installed on a fence at the height of the dog giving them a window to the world they may rarely get to see.
