Do Ultrasonic Cat Repellers Affect Dogs?

Fortunately, there are plenty of natural, homemade methods, which deter cats. Other people like to take the technology road and use the ultrasonic cat repellers. But do ultrasonic cat repellers affect dogs too?

Unfortunately, a drawback of using an ultrasonic cat repellent is that it does affect dogs.

If you have a pet, you will wish to use repellents that keep them safe. While ultrasonic cat repellents can keep cats out, they can also affect dogs.

The repellent works to emit a sound that humans cannot hear, but cats and dogs do. Therefore, the sound will bother your pet dog but will not harm it. 

Is there a Cat Repellent that Doesn’t Affect Dogs?

Having a pet means using methods that are safe for them and will not affect them negatively. There are plenty of other ways to repel cats that will not affect dogs. 

The first way you can repel cats is to use a motion-activated sprinkler. If you are tech-savvy, using a motion-activated sprinkler is a good option. The sprinkler works by being activated when an animal enters your territory.

The method will not affect your dog as most dogs love playing in the water and it will end up being a bit of a toy to them. Cats hate water, and the sprinklers merely wet them, warning them to stay away. 

Another way you can repel cats is to use scents to your advantage. Cats have a strong sense of smell and do not like things that smell too powerful. You can use any scent like citrus, which cats hate.

You can use the scent in powder or liquid form. However, whether you are using a spray or powder, it is important to reapply as it can fade, or the rain can wash it away. Moreover, it would help to use a scent that only cats hate and will not affect dogs. 

Sometimes, it is best to do an all-around check-up in your garden, looking for any holes that give easy access to cats.

You can fix the holes and get a small barrier to keep cats away. You can also make a barrier using plants that cats hate, like lavender, thyme, or garlic.

Do Ultrasonic Devices Hurt Dogs Ears?

While ultrasonic devices do not hurt dog ears, they can cause some issues. The device is a problem for dogs who already have a problem with their nervous system.

While some dogs may find the noise no issue, others can become stressed but gradually get used to it. Nevertheless, it is important to consult your vet before using such devices around your dog. 

In addition, you must also do a trial check to see how your dog reacts to the ultrasonic device. If your dog does not react well, it may not be the best idea to use the ultrasonic device in the long term. You may have to resort to other cat deterrents. 

However, sometimes your dog needs a little time to get used to the sound. Some dogs can give bad reactions first, but then they become accustomed to hearing the sound and not reacting.

On the other hand, any signs of distress and nervousness should not be taken lightly. 

Another problem you may face is your dog getting too excited hearing the sound. Not all dogs will react the same way, and some will make loud excited noises.

However, this can also be a problem as your dog can disturb you at night, and you need to calm it down. In addition, the neighbours can complain about the loud sound. 

It all depends on how your dog reacts to the cat deterrent. All dogs have different personalities. Therefore, they will have their reactions towards the sound. You will not know if the ultrasonic cat repellent works for you until you try it. 

Why Can I Hear the Cat Repeller?

If the frequency isn’t set correctly then there is a chance you will hear the cat repeller too. It could also simply be that you have good hearing.

How to Know If an Ultrasonic Pet Repellent Affects Dogs 

There are a few things you should look out for as you use the ultrasonic pet repellent. For instance, as you begin to use the cat repellent, and your dog can hear the sound, it will try and look for where it is coming from.

You can tell that the ultrasonic pet repellent is affecting your dog if it starts acting weird or suddenly becomes distressed and scared. Your dog can become alert or begin to pant.

Your dog may begin barking loudly at the sound, or if it is around the repellent, it will walk away and look uncomfortable. 

Do Other Animals Hear Cat Repellers?

Yes, other wildlife may also hear cat repellers including foxes and hedgehogs. Birds, however, are not known to be affected by them.


For people who are technologically inclined, using ultrasonic cat repellents is a good idea. The repellent works by emitting a sound that cats hate, causing them to stay out.

However, these repellents also affect dogs, and if you have one, you may face some issues. Ultrasonic cat repellents can affect dogs, but they all react differently towards them. It’s also worth noting that ultrasonic repellers will impact wildlife too, such as hedgehogs.
