Are you curious why your dog loves to chase squirrels or rabbits around the house or park? If outings with your dog are chaotic because of his tendency to chase other animals, or if your sweet pup has ever horrified you by bouncing up with a wiggling rabbit in his mouth, you might have a dog with a strong prey drive. Here's everything you should know about prey drive in dogs and what you can do to manage it in your pooch.
Why Does My Dog Chase Squirrels?

While dogs have evolved away from being predators in the same way that wolves are, most have retained the ability and desire to hunt. Thanks to breeding, this drive to hunt manifests itself in different ways in different breeds.
Dogster explains that the prey drive involves five different behaviors: searching, stalking, chasing, biting to grab and biting to kill. Among the dog breeds with a high prey drive, these behaviors manifest differently according to breed. Herding breeds, for example, have a strong chase instinct, while hounds like to stalk and flush out prey.
Terriers originally bred to hunt and kill rodents and other small game still possess a strong drive to do so. Of course, not all dogs have a strong prey drive, and many dogs are content to express whatever mild predatory instincts remain through play, such as chasing a ball or shaking the stuffing out of a toy.
Prey Drive vs. Aggression
While a strong prey drive can sometimes look like aggression — especially to your dog's prey — there is a key difference that is important in understanding your dog's behavior. Dog aggression is driven by strong emotions, such as fear, says Positively, whereas prey drive is instinctive.
Another key difference is that aggressive dogs desire to increase distance between themselves and the object of their aggression. When operating under the influence of their prey drive, dogs are seeking to get closer to their target. This is good news for dog parents of dogs with strong prey drives, because it means that since there isn't an emotional component to overcome, prey drive is often easier to manage than emotion-based aggression.
Can a Strong Prey Drive Lead to Behavior Problems?
A strong prey drive in dogs can be a problem if it means your dog chases anything that moves. While this can be fun when you're up for a game of fetch, it's not such a good time when you're out for a walk and your pup tries to tear after every squirrel, rabbit or cat that wanders into his peripheral vision.
If not properly restrained, dogs with a strong prey drive may also engage in dangerous behavior, such as chasing cars or attacking venomous snakes, says Dogtime, and your dog may be so focused on his prey that he ignores your commands or refuses to come when called. Unfortunately, small pets, such as rodents, birds, cats and even small dogs, may not be safe around a larger dog with an overactive prey drive.
