Introduction: Dog Anti Bark Screen......

.... not a concept you come across every day :)

The background to this is that Maisie came to us as a rescue dog with a lot of baggage. She has been bred over generations to be a livestock guard dog whose mission is to warn the herder of any danger to the herd by barking, here lies one of the problems, her favourite occupation when in the house is watching window TV, any passing dog needs to be barked at!

We tried bark collars (not resorting to electric shock type) they work to an extent but she managed to pop 2 of them off her collar, a better method was required, an anti bark screen!

Step 1: What Is Required to Make a Bark Screen?

The parts required are:

  • A piece of 5mm perspex around the size of the window to be screened
  • A piece of LCD smart film, of similar size, with transformer
  • Some pieces of 20mm and 5mm MDF
  • Wood glue, screws and M4 trap nuts
  • A strip of 1.5mm aluminium
  • Remote control mains switch I had one spare from a set of four from reichelt that was perfect for the job

Tools required:

  • Bandsaw/hand saw
  • Router
  • Pistol drill
  • Screw driver bit

Step 2: The Build

The LCD smart film needed to be squeegeed onto the sheet of perspex in the same way that tinted window film is installed (lots of videos on YT that cover this, I didn't film it as I was concentrating too hard on avoiding air bubbles).

With the router I cut a groove in a piece of MDF that will be the base, then cut the bottom edge of one of the MDF screen clamping uprights to fit snuggly into the slot.

Step 3: Room for the Wiring

Again with the router I cut a groove for the perspex to fit into and then some slots to feed the wiring from the smart screen to the transformer. I also cut a strip of aluminium to hold trap nuts to fix this together using M4 countersunk screws rather than using wood screws, (I always find using woodscrews in MDF to be a bit weak).

Step 4: First Power

After screwing it all together it was time to plug in and give it a try.

Step 5: In Place in the "dog TV" Window

I put the screen into the "dog TV" window and gave it a try, it works! If Masie starts to take an interest in a passing dog, I can just hide it with a press of a button on the remote control before she even starts barking!

Sorry about the bleached out start of the video, when I get closer you can see the effect.

Congrats on being a finalist in the "Plastics" contest, good luck.

Masie is such a lucky dog! I was afraid this would be another idea to shock a dog into submission, but you took your time and your skills to create something unique. Thanks for sharing!

That's a creative fix for a annoying problem. She's a sweet looking pup.

I have a Lab that likes to guard the window too, although not to that level. Fortunately she likes treats and praise more. Using a technique from the "Dog Listener" book, when she barks I thank her then place myself between her and the window, when she stopped barking she got a treat then praise. She eventually understood and I didn't have to get between her and the window, just a voice command. The treats are few now but always praised with "good girl" and a pet.. Interesting I think she barks sometimes just to see if she gets that treat :). Might not work for everyone but it sure helped me.

If Maisie had been a foody dog I would have gone the same route, trouble is she is not at all tempted by treats.... complete opposite to our greyhound who would sell her soul for a treat. :)

Maisie looks a little like a Norwegian Elkhound and German Shepard, very good looking dog! I think each dog and situation is different and you got the result you were looking for. Well done.

@rayp, Thanks, she is a Sarplaninac, named for the Sar mountains in Yugoslavia where she would have served her guard duty. They are big furry and very good company :)

So what does the screen do to stop the barking? If it doesn't give the dog a shock or some kind of a unlikeable feeling, how will the habit ever be cured? Do you have to wait for the dog to start barking before you turn on the gizmo? That would require you to sit beside the dog and watch for the animals that he barks at so you could hit the switch before the barking starts.

Negative reinforcement is not really the best solution to any behavioral issue but rather a fall-back. If you remove the stimulus (blocking sight), then the behavior goes unrewarded without being punished.

But it's ok for people right?

You could add a Movidius camera and load in dog images. The artificial intelligence would trigger the screen whenever a dog went by, or if the dog was barking. $79 for the USB stick. Add some programming and voila.
