Will a Fox Attack My Dog? An Evidence-Based Analysis

If you have a dog and you see a fox in your backyard or while you're out for a walk, how concerned should you be about a potential fox attack? While foxes are likely to stay away from larger dogs, there are times when a fox may see a smaller dog as a potential meal and act aggressively if it feels threatened.

This article will delve into the research of wildlife biologists and animal behaviorists to determine what factors influence a fox's behavior toward dogs. From learning about fox hunting behaviors and territoriality to finding out what safety measures you should take, this evidence-based analysis will help you better understand the actual threat that foxes may pose to our pet dogs.

Why Do Foxes Attack Dogs?

There are a number of reasons why a fox might attack a dog, and many of them are based on the fox's natural instincts and behaviors. According to research cited by PawSafe, territoriality is a major reason, as foxes will protect their territory from perceived threats like dogs, especially if the dog comes too close to where fox kits are living. A study referenced by SamTheDogTrainer explains that foxes are pack animals, and as a result, they are suspicious of other canines that they don't know, including domestic dogs, which they may see as a threat to their pack.

Foxes may also attack dogs based on their predatory instincts, especially if the dog is small, weak, or seems vulnerable. As DogAcademic explains, foxes are natural hunters and have been known to hunt small animals like rabbits, so if a puppy or toy breed is left alone in an area where foxes are known to live, they may be at risk of an attack. A mother fox is also more likely to attack a dog if she feels her kits are threatened, regardless of the dog's size.

Environmental factors, such as a lack of food or the loss of natural habitats, can also lead to an increase in fox attacks on dogs as foxes start to see dogs as competition for resources. Research from PMC has shown that domestic dogs and wild foxes often come into contact with each other in shared urban and suburban environments, and this can lead to territorial and resource competition that may result in an attack.

How Foxes Tend to Interact With Dogs

Foxes are not known to pose a threat to domestic dogs, and there have been only a few confirmed cases of foxes killing very small dogs. According to Wildlife Online, the only known instance of a fox killing a dog involved a Chihuahua in Poole, Dorset in 2010. In general, dogs are more likely to threaten foxes and may even help control urban fox populations by chasing or otherwise disturbing them. Research cited by SamTheDogTrainer showed that feral dogs frequently disturb and chase foxes, and 15% of fox cub deaths in one study were blamed on dogs.

Foxes are usually cautious around medium to large dog breeds, but Wildlife Online says there have been some reports of foxes that were not scared away by dogs "intimidating" people walking their dogs. Foxes are more likely to prey on cats or small animals like poultry than dogs, although Dogster says that while cats are more likely to be attacked by foxes than dogs, the number of cats killed by foxes is still relatively low. A camera trap study in Chile observed frequent interactions between domestic dogs and wild foxes in shared urban/suburban habitats, which could lead to disease transmission between the two species.

Zoonotic Diseases and Health Risks from Fox-Dog Interactions

Dogs are known to be important reservoirs for a number of zoonotic diseases that can be passed to humans, including rabies, Pasteurella, Salmonella, and Leptospira, according to a review of zoonotic infections published in PMC. Meanwhile, foxes can transmit diseases such as rabies, sarcoptic mange, lungworm, and a variety of bacterial pathogens to dogs, as reported by ShootingUK.

Although the risk is relatively low, it’s important to take precautions because certain diseases that foxes can transmit to dogs, such as sarcoptic mange, can be severe. Wildlife Online explains that foxes can also carry parasites like Toxocara canis, Echinococcus multilocularis, and Trichinella spiralis, which could potentially be transmitted to dogs. To help reduce the risk of disease transmission, make sure your dog is up to date on their vaccinations and parasite prevention and try to prevent them from coming into contact with foxes and their dens.

How to Avoid Foxes and Keep Your Dog Safe

Don’t leave small dogs alone outside, even in a fenced yard, because they may be at risk of fox attacks, says The Humane Society. Walk dogs on a leash and steer clear of areas where foxes are known to den or are often seen, according to Life With Dogs. Make sure your garbage and pet food are secure, and eliminate any other food sources that may attract foxes to your property, says DedhamVetAssociates.

Use noise devices, motion-activated lights, or repellents to keep foxes from denning in spaces near your home, says WildlifeHelp.org. Keep your dog’s vaccinations current and use parasite prevention medications that your vet recommends to help reduce the risk of disease transmission.

First Aid and How to Handle Fox Attacks on Dogs

For minor bites or scratches, the Mayo Clinic recommends washing the wound with soap and water, applying antibiotic ointment, and covering with a bandage. That said, if the wound is deep, bleeding profusely, or looks infected, you should make sure to get your dog to the vet as soon as possible.

If the fox was potentially rabid, Mount Sinai advises talking to a doctor about the possibility of your dog getting a rabies vaccination. According to VCA Animal Hospitals, you should make sure to keep your dog as still and calm as possible after an attack and make sure to transport them to the vet in a safe manner. Once you get to the vet, you should make sure to follow their instructions for treating injuries, monitoring for shock or infection, and giving any necessary medications.

Conclusion: How to Reduce Risks When Living With Urban Foxes

While fox attacks on dogs are relatively rare, responsible pet ownership is important for pet safety. This includes understanding fox behavior, territoriality, and the potential for disease transmission. To reduce the risk of an attack, it's important to supervise pets, secure yards and homes, and use preventive veterinary care.

If an attack occurs, prompt first aid and veterinary care is important for the dog's safety. With knowledge and proactive measures, dogs and foxes can coexist in urban and suburban environments.
