I know it's too close to Christmas to get presents now, but think about this one later for your pup(s).
The Dog Peek would be great for the dog who can't see what's on the other side of the fence or maybe even the front door.
This made me laugh the first time I saw it, but then realized how cool would that be for your dog? Don't know whether it would slow down the barking or heat it up 'cause they can see. Either way, I think it'd make your pooch feel more in touch with the other side of the fence.
