Part of the responsibility of pet ownership means being aware of the dangers that your dog or cat may face from wild animals.

Here is a rundown of 10 common animal attackers, along with advice on what you can do to protect your pet from their dangers.


Every summer, many pet cats and dogs go missing because of these fierce creatures.  Elizabeth Rozanski, assistant professor of emergency and critical care at Tufts University's Foster Hospital for Small Animals in North Grafton, MA, confirmed Simpson's fears about coyote behavior: "Coyotes definitely do attack. Unfortunately, what coyotes do is kill cats and dogs, not injure them," Rozanski said.

Contrary to what many suburbanites believe, Coyotes are found all over North America and make their homes in parks, river corridors and even cemeteries. So, if you live in coyote country, you should think twice about letting your cat or small dog out overnight.  Do not leave pet food out overnight, as this attracts coyotes, and be sure to secure your household garbage, as these predators and others are resourceful scavengers.


Snakes pose another lurking danger to your pet. ABC News reports that most snakebites in the United States come from the pit vipers, a family of venomous snakes that includes water moccasins and copperheads, found in abundance all over North America. Attacks by these reptiles most often occur when a dog is moving about through grass and sniffing through burrows.  

Though it is difficult to prevent a snakebite, they are usually not fatal. If your pet is bitten by a snake, immobilize it, and bring it to your veterinarian immediately.

Cougars -- also known as mountain lions or pumas -- are found in the American far west and southwest. (In the eastern United States, the only confirmed population is in rural Florida, where the cougar is known as the Florida Panther.) Once hunted almost to extinction, cougars have increased in numbers in recent years and sightings are no longer rare. These big cats pose a serious danger for outdoor pets if you live in regions where they are found. Though cougars are more interested in hunting livestock, they will attack a pet if an opportunity arises.  

The owner of a would-be victim who watched as his dog was attacked by a cougar told ESPN.com, "If I'd gotten out there five or 10 seconds later, there was no way the dog would have survived."

While rare, attacks on humans have been reported as well, so if you see a cougar on your property, notify animal control or the police immediately.  


Raccoons pose a danger to your pet, even in urban environments. "It's more likely that the raccoon will be attacked [and retaliate], than the other way around," Rozanski said. Their primary danger to your pets is diseases that they carry, specifically rabies.

Raccoons are attracted to open garbage cans or any food that is left out for pets. You can discourage them from remaining near your property by securing your trash and not feeding your pets outside.

Though innocent looking, the damage that a squirrel can inflict may require a trip to the vet. Most squirrel attacks arise when a dog or a cat attempts to catch it, and while your pet will likely win the battle, the squirrel does have sharp teeth and claws that can damage soft tissue. 

The best way to prevent injury from a squirrel is to be mindful of your animal at all times when outdoors.


Indigenous to the southwestern United States, scorpions pose a threat to pets -- and  pet owners -- who live there.  Dogs and cats should be watched closely and if your pet appears to be tracking something to catch, investigate and make sure it isn't chasing a scorpion.

Scorpion venom can be deadly, so if you live in scorpion country and your pet is limping or appears sick after spending time outdoors, it should be brought to the vet for immediate medical attention. Do not leave footwear or clothing out during the daytime, as scorpions like to take shelter in and under these items. 


The porcupine is found all over the United States, and these quill-bearing rodents oftern are in search of a source of salt such as certain plywoods or sweaty clothing. 

"If you're going to let your dog run free in the woods, that's fine; it's fun. Just be aware they can get injured," Rozanski said.  The porcupine's barbed, loose quills can easily embed themselves into your pet -- especially curious dogs -- requiring unpleasant hours at the vet to be removed. 


If your pet encounters a skunk in the wild and gets 'skunked', it will be treated to a smell as unpleasant as a punch in the stomach.  Skunks also have very powerful front claws that they use to burrow, which can very quickly be turned against your pet if the skunk feels threatened.  

Skunks can also be carriers of rabies, so if you smell something painfully pungent while out with your pet, be aware that a skunk might be lurking.

Ground hogs

These large rodents generally attack only if they perceive a threat from your pet, but will do so with powerful claws and front teeth. According to National Geographic: ground hogs are native to all of North America and are most frequently encountered where a field meets a forest, so they can commonly be seen in newer housing developments.

In most cases, an injury to your pet is the result of it getting too close for comfort to the ground hog, so this is another case in which keeping watch over your pet is important.


Wild rats are everywhere. They're hardy, intelligent, aggressive, and comfortably at home in rural and urban environments. Similar to that from raccoon,s their biggest threat from rats is the diseases they might carry. Keeping your garbage contained is the best way to prevent encounters with rats. 

Though your cat or dog will probably be the winner in any encounter with a rat, check and make sure that they weren't injured during the scuffle.

An ounce of prevention

The best policy when it comes to protecting your pet from the dangers of wildlife is to be mindful of your animal at all times. Attacks from wild animals, large and small, can occur anywhere from inside your house to a state park. If you're in a high-risk or questionable area, don't let your pet off leash and always be sure to have an emergency vet's number handy in case of an attack.
