How to Tone Down That Plastic Dog Collar Click (and Why)

How to Tone Down That Plastic Dog Collar Click (and Why)

Plastic collar clicks are loud! And we often snap them right next to our dogs’ ears. I realized I habitually dampen the sound with my hands; this practice undoubtedly came from my experiences with little Zani, who was clinically sound phobic. During bad periods, she would startle at any kind of sudden noise.

I imagine I’m by far not the only one who does this. But in case there are dog owners who haven’t worked this out, here’s a kind thing you can do for your dogs. If you use collars or harnesses with plastic snap buckles, you can use your hands to damp the sound of the click when you snap the collar closed.

I wanted to know just how loud the snap might be and how much quieter I could get it. I ran a seat-of-the-pants experiment with a good mic and a sound analysis app. The click was about 83 decibels at its peak frequency, undamped. (That’s just one measurement; the intensity of the sound will vary with the type of collar, the flexibility of the plastic, the distance from the ear, and many other factors.) Eighty-three dB is not normally in the painful range for humans (or likely dogs), but since the snap is an impulse noise, it can be shocking to the ears at that level. One study with rats showed that a sudden sound can evoke the startle response if it is between 80–90 dB (Ladd et al, 2000). Bingo.

If you hold a plastic buckle three inches from your ear and snap it together, you will feel an uncomfortable sudden blast of sound pressure in your ear. I’m guessing it doesn’t feel great to dogs, either.

This plot represents that sound. It has frequency on the x-axis and sound pressure level (roughly the same as volume) on the y-axis. More about the plots at the end of the post.

How to Dampen the Sound and How Much That Can Help

Many of you have probably figured out, either analytically or subconsciously, to hold the pieces of the buckle a certain way to reduce that loud click.

But I bet you haven’t seen how much it helps if you dampen the snap with your hands.

If you simply press the two parts of the snap collar together, they click loudly.

But if you use your fingers to dampen the sound, you can lower the intensity substantially. Not all collars have the same design, but I got an optimal reduction of the sound when I fit my fingers into the curves of the receptacle as shown in the next image. I not only damped the vibrations; I could slow the progress of the plastic prongs. I was able to ease them over the internal part that makes them snap (you can see that in the movie). You can also get a decent reduction in the sound if you hold the flat parts or put your whole fist around that side of the buckle, but though it will be quieter, the snap will still be sharp.

Nice quiet click: 54 dB

The damped click is about 54 dB, 29 dB lower.

54 dB and no sharp peak; this is a thud, not a click

In the weird world of logarithmic scales, that translates to the loud click being almost 1,000 times louder than the damped one. See the note at the bottom of the post if you are interested in more detail about the math behind these diagrams.

Here’s a quick video showing how I optimally damped the click of the collar.

Be careful with damping, though. I did pinch my thumb once and got a blood blister.

Some people with sensitive dogs avoid snappy collars and harnesses entirely. I find them handy enough that I do use them but take care to keep my dogs’ ears (even my non-sensitive dog) from being clobbered by the sound. I hope the points in this post weren’t painfully obvious to every dog guardian already.

What things do you do to improve your dog’s sound environment?

Sciencey Addendum

The diagrams I use above to show the comparative sound pressure levels in decibels (dB) are in the form of a Fast Fourier Transform. (Believe it or not, the previous link is one of the more understandable explanations of the FFT.) What the FFT does is transform a signal, in this case a sound, from the time domain to the frequency domain. In these diagrams, the FFT is showing the sound pressure level (roughly speaking, the volume) at its different component frequencies. There are at least three interesting things about the diagrams.

First, you can “see” that the undamped click is much sharper. Check out the sharp peak on the plot. That’s a click. The damped sound is more like a thud. It’s quieter but also spread out farther over a range of frequencies. That makes the sound less startling.

Second, the sound pressure level stays high in the frequencies above the peak in the undamped version. The overtones and other contributing high frequencies are free to do their loud thing. You can see in the damped version that I pretty much killed those higher frequencies with my fingers. What nice news for dogs, who hear these high frequencies better than we do.

Third, those two other “humps” to the left of the peak frequency in the damped diagram are interesting! But I can’t explain them, except that I changed the contour of the sound by slowing down the plastic prongs as they passed over the internal clasp. But I’d like to know more about what’s going on. It’s possible the lowest hump is now the fundamental frequency. I’ll do it again one of these days and check out the center frequencies of the other humps and see if I learn anything interesting.

6 Ways To Prepare Your Dog for Fireworks Starting TODAY

6 Ways To Prepare Your Dog for Fireworks Starting TODAY

Is your dog scared of fireworks? Don’t wait until Canada Day or Independence Day to start worrying about it! You can make a plan and take action now to help your dog be a bit less afraid of the unpredictable scary sounds of fireworks, firecrackers, whistles, and even guns.

Get Ready

Here are some things you can do today.

1. Check with your vet about medications
If your dog gets very anxious about noises and you have never talked to your vet about it, do so now. He or she may be able to prescribe something to help. And if you can’t get in before the holiday, do your best with some of the other ideas here to get through it and call your vet as soon as you can. This is a long-term problem. Sound phobias tend to get worse and are not something to be taken lightly.

2. Countercondition to noises
Get some great treats and start carrying them around at home. Whenever there is any kind of sudden or startling noise, but especially stray bangs and booms as people start to test their noisemakers, rain treats down on your dog. Use those special treats only for noises. Don’t pass them out for nice behavior (use something else for that!), and don’t ask for any particular behavior from your dog when the noise occurs. Just give the special treats. This is sometimes referred to as ad-hoc counterconditioning, and here is an excellent article about a survey that indicated its efficacy.

You may wonder why I am not recommending buying an app, CD, or YouTube video with fireworks sounds to “practice” with. Performing desensitization/counterconditioning with sounds is tricky.  People who haven’t done DS/CC before run a real risk of scaring their dogs further instead of helping them, and many of the sound collections are poorly designed for DS/CC anyway. This is why I am suggesting straightforward counterconditioning, which uses environmental noises that are happening anyway. Save the formal training for well after the holiday, when scary noises are less likely to happen.

3. Create a safe place
Make (or adapt) a safe place for your dog. Keep in mind that the flashes of light that come with big fireworks displays can be scary too. Consider a method to darken any windows nearby or shield the safe place with a cover if necessary. Be aware that the low-frequency sounds of thunder are physically impossible to mute with the amount of absorbent material we can use at home. But being underground can usually help a bit, so basements are a good option for some dogs. Get the best protection you can in a basement or your most internal room. Despite the marketing claims, dog crates with walls a few inches thick can’t dampen low-frequency sounds significantly. Putting a soft cover on a crate does nothing to prevent the sounds of thunder from entering, although it may cause an auditorily cozy feeling because it deadens some of the reverberant sound in the space.

4. Play sound or music
Experiment with sound masking or music to find out what is most helpful for your situation. Try some kind of recorded white noise, natural noise, or music to mask the pops and booms. (Even a noisy food toy can be helpful.) This approach is evidence-based and called sound masking. Start working on it today.

And here’s a tip: the lower the frequencies included in the masking or music, the better it can hide those low-pitched booms (Kinsler, Frey, Coppens, & Sanders, 1999, p. 318–320). So if your dogs are already habituated to pounding rock music or some other music with a lot of bass or percussion, play it! It can mask some of the scary noises from outside your house more effectively. Taiko drumming is great if your dogs are accustomed to it. You can buy a few songs and loop them or find some on YouTube. But first, be absolutely certain that the music itself doesn’t scare your dogs. If they are already sensitive to booms, it probably will.

Household appliances can help. Some floor fans hit fairly low frequencies and can be helpful. You can run the dryer (no heat) with a pair of sports shoes in it for some booms that will probably be familiar and not scary. You’ll need to find the line of best fit for your dogs.

You can also try the Bang-Dog Playlist from Triplet Noir Studios. These are heavy metal selections (be aware that some of the language is not family-friendly). Before anyone mentions it: heavy metal has not ranked well in the dogs and music studies, tending to make shelter dogs more agitated. That’s not surprising. People might find it almost sacrilegious that I am suggesting heavy metal. But if you play it already and your dogs are fine with it, they are habituated. In that case, these playlists could be the perfect thing for you.

5. Practice going out
Make a plan for taking your dog out to potty. Do you know when the noise is usually at its worst and can you work around that? Are your fences and/or leash and harness secure? Dogs who are usually sedate have been known to panic and run off on noisy holidays. Don’t let that happen.  Keep your gates locked, your dogs’ ID tags on, and put some redundancy into your safety system.

6. Comfort your dog if that helps
LOSE that idea that there’s something wrong with comforting your dog if that’s what your dog wants. Helping a dog through a tough time is not “coddling.” Assess what is most helpful to your dog: a cuddle, food after every thunderclap, some lap time, sweet talk, being in their crate with a food toy, or hiding by themselves in a secluded place. Then help them do it.

The best part of thunderstorms: spray cheese!
The best part of noisy holidays for Summer was spray cheese!

How I Helped My Dog Love the Sound of Velcro

Velcro, a type of fastener with two different fabric surfaces that adhere to each other, typically makes a loud ripping noise when pulled apart. Some dog harnesses, coats, medical supplies, and other gear use Velcro closures.

This ripping sound can be aversive. Some sound phobic dogs are triggered the first time they hear it. And some dogs who are OK with most sounds may find it unpleasant when Velcro is unfastened close to their ears.

I recently “inoculated” my dog Zani against fear of the Velcro ripping sound. Zani has a Continue reading “How I Helped My Dog Love the Sound of Velcro”

Introducing a Puppy and a Sound Sensitive Dog: Preparation Pays Off

Introducing a Puppy and a Sound Sensitive Dog: Preparation Pays Off

Last month I posted to show how Marge Rogers introduced a friendly but possibly overenthusiastic dog to a very small puppy. But what if the challenge were a little different? What if your resident dog were both fearful of new dogs and sound sensitive?Young puppies are not exactly quiet!

My friend Kelly Viscosi has stepped forward to share how she prepared Dennis, her 9-year-old vizsla, to meet Saya, the new vizsla puppy. But actually, the story starts long before they meet, because Kelly did a ton of very clever preparation with Dennis.

Here are her words.

When we were expecting a puppy last summer, I asked the breeder to send me audio of the puppies crying and whining at their loudest (which happened to be right before breakfast time for them). She video taped it with her smart phone and sent it to me.

Dennis and stuffed dogFirst I classically conditioned Dennis to just the sound of the crying puppies. Once I was getting a good positive conditioned emotional response to this, then I set up a stuffed dog in a crate, placing a small, wireless speaker under the stuffed dog. At random times throughout the day, I would play the audio and treats would rain from the sky right in front of the crate with the stuffed puppy.

Dennis and stuffed dog 2Before long, Dennis would just choose to park himself in front of the crate, waiting for the “puppy” to cry. From here, I also began putting the stuffed puppy in an ex-pen (also with wireless speaker under stuffed puppy). We repeated the same thing: puppy cries, treats rain down. This worked very well to prepare Dennis, who is sound sensitive AND fearful of dogs outside the family.

When we brought the real puppy home a month later, he was very well prepared for all the extra noise his baby sister made. She would cry/bark, and it sounded just like the stuffed puppy had, because he had been listening to his sister and her littermates for several weeks now. I still tossed treats to Dennis every time his sister cried or whined, and he would park himself a few feet away from the ex-pen, waiting for her to cry so he could get treats. 

Yes, he gained some weight during this time, but it was well worth it because he had a positive association and we just reduced his calories a couple months later

Classical Conditioning Done Well

I just have to editorialize about this, to elaborate a bit on all the things that Kelly did right.

  • She got a recording of the exact sounds that Dennis would be exposed to.
  • She used classical conditioning: she played a few seconds of the crying, then rained the treats down. Notice that she did not just leave an audio recording going. She played a short segment and followed it with treats.
  • She played the noise (and followed it with treats) at random times throughout the day. She made it clear that the noise, and the noise alone, predicted the special treats.
  • She then made a further association: she made the sound source appear to be the stuffed dog. Even though Dennis doubtless knew that this was not a real dog, it gave a focal point for the sound and a visual that was similar to what he would later see with the real puppy.
  • She did the “noisy puppy” show in two different locations, the crate and the ex-pen.
  • She didn’t skimp on the quality of the the treats.

This work she did made a huge difference for Dennis. He could have been miserable from the noise and the new stranger. But with Kelly’s careful preparation, the arrival of the puppy meant enrichment opportunities for him. How cool is that?

Dennis and Saya

But Wait–There’s More!

Here’s some other great training Kelly did before the pup came. She set up a group mat exercise for Dennis, the future puppy, and Trixie, her other senior dog. She used the faithful stuffed dog as a stand-in for the puppy. Again, Dennis surely knew this was not a puppy. But the exercise helped create a routine. He learned that the object on the adjacent mat getting a treat predicted his getting a treat. Learning the routine was another thing that helped him adjust faster to the real dog when she came. (Kelly mentioned that Trixie, the black and tan senior dog, was gregarious and happy with other dogs, so this exercise was just a bonus for her.)

 

One of my favorite things in life is seeing the imaginative and thoughtful things that people all over the world do to make their dogs’ lives better. I hope Kelly’s work with Dennis plants some seeds of ideas out there for others who are preparing resident dogs for a newcomer.

Care to share? I bet there are some other great stories out there.
