Colorado’s foothills and mountains offer stunning natural beauty and amazing wildlife. Unfortunately, though, Colorado animal encounters can easily end in injury for our pets.

In this state, especially, it is vitally important to keep your pets controlled at all times, and for everyone’s safety, be sure to enjoy wildlife from afar. At Veterinary Specialists of the Rockies, we see pet-wildlife interactions every day, and most of the time, those animal interactions don’t go well for our pets. From porcupines to mountain lions, here’s information on keeping your pets safe from wild animals and how to know when veterinary care after wildlife attack is necessary.

Top Five Colorado Animal Encounters – and How to Protect Your Pets

1. Porcupines

Particularly from spring to fall, we often see pets (especially dogs) who were roaming the property or were off leash and have encountered a porcupine. Since this is very painful, and can certainly lead to an infection, it is always recommended to seek care from a veterinary hospital.

Usually, patients need to be heavily sedated to remove the quills as they are barbed and difficult to remove. Quills can also break off and be embedded in the tissues. These quills can then migrate through the tissues underneath the skin and can occasionally cause very serious problems such as infections behind the eye, in the chest, or worse. Follow-up from a porcupine encounter includes pain management and antibiotics under expert veterinary supervision.

2. Snakes

Rattlesnakes are common wildlife encounters in the Colorado foothills, starting in the spring on warm days, through the summer and fall. Some snake bites are dry bites (with no venom) and some species, such as Bull snakes, don’t have venom. Most snakes only bite as a last resort of defense. But, when they do bite, effects can begin quickly with bites from venomous snakes often having devastating consequences without treatment. Snake venom can result in edema (swelling of the area), tissue damage, coagulation disorders, pain, and more.

The only reliable treatment for snake bites is antivenin, which is a very expensive drug (even up to $1000 per vial), and large dogs may need several vials. Snake bites can be very painful, and without treatment, many complications can arise. Steroids, antibiotics, Benadryl and other medications are usually not indicated for snake bites and have no proven benefit.

3. Deer, Elk, and Other Antlered Animals

Although pets in Colorado can come into contact with horned and antlered animals year-round, these animals tend to get more “attitude” in the fall during the rut and can be quite aggressive and territorial. Antlers are also more prominent during that time of year!

It’s not uncommon to see dogs get stomped, kicked or “gored” by deer, elk, or other animals with antlers. Because antlers are very hard and very sharp, injuries can be very severe and require veterinary care after wildlife attack, including emergency surgery to repair body wall problems, holes in intestines, internal bleeding, infection, and more.

4. Large Predators: Mountain Lions, Coyotes & Bears

There are many large predators in Colorado, including mountain lions, bears, coyotes and even large predatory birds. With fewer and fewer spaces for these predators to roam, it is increasingly common to see these animals in neighborhoods.

These animals may target small pets, but even larger dogs can sustain serious bite wounds or trauma. Understanding mountain lion safety for pets and protecting dogs from coyotes in Colorado is essential. Keeping control of your pets and being very cautious when hiking or exploring the wilderness with pets will help avoid these situations.

5. Small Critters: Skunks, Raccoons & Rodents

These animals may not seem like much of a threat, but can occasionally cause illness of a different kind. Rodents, racoons and more are known to be carriers of Leptospirosis. This bacterial infection is spread through urine, so your pets don’t need to have direct contact with the animal to have an exposure risk. Vaccination is available to help minimize risk of infection and sickness from this disease, but the vaccination is not 100% effective and often requires regular revaccination to ensure proper protection.

Skunk spray is often more of a nuisance. However, with severely affected animals, we can sometimes see anemia or ulcers in the eye which require treatment. A safe de-skunking remedy is a mix of 1 quart 3% hydrogen peroxide, ¼ cup baking soda, and 2 tablespoons liquid dish soap—use gloved hands to apply and rinse thoroughly.

When to Seek Veterinary Care After Wildlife Attack

Colorado foothills wildlife encounters are a real threat to pets and can easily be an emergency situation. Immediate attention is needed if your pet exhibits signs of serious injury—bleeding, difficulty breathing, swelling, or lethargy. Also, watch for delayed signs like fever, swelling, or limping—especially after encounters with porcupines or antlered animals. With predator injuries or possible infections like leptospirosis, promptly contact your family veterinarian for evaluation and treatment or take your pet to an emergency veterinarian such as Veterinary Specialists of the Rockies.

Expert Tips for Keeping Pets Safe from Wild Animals

• Stay alert in areas where wildlife is common, especially at dawn and dusk.
• Use a leash and keep pets close to minimize surprise encounters.
• Avoid feeding or approaching wildlife, even unintentionally (like raccoons or rodents from trash).
• Know your local wildlife activity patterns. Understanding behavior is the first step in keeping pets safe from wild animals.
