Your dog’s been barking at the fence all day, there’s most likely something on the other side of it that they can hear, but they just can’t confirm that it’s nothing to worry about, so they’ll just bark endlessly. Every dog should have a point of view. The Pet Peek window can easily make that possible. If only there was a window you can install on your fence to allow your pooch to peek on the other side. Alas, there is! The PetPeek Fence Bubble Window is actually a bubble that you can install in your wooded or opaque fence so that your dog can have something to look at besides the side of a fence.
