Why do dogs love catching and eating flies?

Catching and eating flies somewhere makes your dog happy. But do you know so many reasons are there due to a dog’s love of doing so? Well, the possible reasons are as follows:

Flies are creating nuisances for them

First of all, do understand that dogs are very particular about their surroundings. If they notice something inappropriate in their surroundings, they start behaving annoyingly. Similarly, with files and bugs, they notice that Flies and bugs appear to be a nuisance to them, and to get rid of them, they start catching and eating them. Sometimes it is so extensive that they don’t even notice other things happening around them.

Natural prey drive

Dogs come up with a natural prey drive. It may appear to be astounding, but yes, it is true. Along with biting to grab and biting to kill, dogs also start catching and eating flies. Some dog owners never agree to the behavior of dogs and consider that it is possible only in sporty dog breeds. But this is not true because it is a natural behavior that is noticeable in almost all dog breeds.


There is a possibility that when they first catch and eat the flies, you have encouraged them. Dogs are quick learners in such things, and likewise, they learn encouragement very quickly. Therefore, if you notice your dog doing such a thing, stop them immediately and handle the situation with a calm tone. Showing aggression at this moment leaves a negative impact on them.

Your dog is feeling bored

When your dog is feeling bored, they try to look out for certain things that can make them feel excited again. If they come across flies in their surroundings, they will love to catch and eat them. You notice your dog in a different zone at that moment. But do not encourage them to do it.

Health issue

A health issue is also responsible for such behavior in dogs. If your dog is experiencing a seizure, the chances are that they will start doing such activities. In this case, seizure should not be confused with muscle spasms, drooling, or uncontrolled movements. Have a conversation with the vet and let him diagnose your dog.

Problem with the eyes

Problem with eyes can also be a cause for it. If there is some dust and debris in the eye, this will appear like a bug to them, and your dog may start engaging in the activity to catch it.

Can obsessive-compulsive disorder cause a dog to catch and bite flies that don’t exist?

Unfortunately, yes. If your dog is a victim of obsessive-compulsive disorder, then everything from chasing laser pointers to catching flies is common. It is very difficult for you to fix this behavior initially.

What we learned from all this

Have a conversation with the veterinary doctor and discuss this particular episode in detail with him.
