If you’ve lost your pet, please visit Larimer Humane Society in-person as soon as possible. Each month, hundreds of lost dogs, cats, rabbits, reptiles, and even barnyard animals find temporary, safe shelter with us. 

Please do not email us for lost or found pets. Telephone the shelter immediately at (970) 226-3647 if you have found a stray animal.

If you’ve lost your pet, you must come to the Larimer Humane Society in person to submit a lost report. Sending email or registering your pet online will NOT put the information into our system.

NOTE: Proof of ownership is required to reclaim your lost pet.

Larimer Humane Society is open seven days a week. Click here for our hours and location . Because we receive so many stray animals each month, we are unable to verify by telephone if your animal is at the Humane Society. It is very important that you visit the animal shelter in-person every two-three days.

While at the shelter, be sure to check our Adoption Center as well as our Lost & Found Center. Since stray animals brought to Larimer Humane Society are held for five days before being evaluated for adoption, your pet may already be available for placement.

If your animal is at the shelter, you will be required to pay impound and board fees. If the animal does not have a current Larimer County license, you will also be required to purchase one. Fees vary, depending on whether your animal is wearing a current license and how many days they have been at the shelter.

If your pet is not at Larimer Humane Society, a staff person will assist you in checking our found reports. Be sure to bring a current photo of your pet to assist us with accuracy in breed and color(s).

You may also want to:

• Place a Lost Pet ad in the local newspaper
• Post fliers at local veterinary hospitals, feed stores and other privately owned business that will allow it. Please note that posting signage on public property is illegal
• Post a flier on the designated signage board at the dog park
• Notify your neighbors and ask for their assistance. If you’ve lost a cat, ask your neighbors to check their garages, tool sheds, and barns in case your pet is confined.
• Place your cat’s litter box or an article of your clothing outdoors to help your cat locate your home. Indoor-only cats may need assistance finding their way home.
• Call for your cat in the evening or early morning hours when the neighborhood is quiet. Shy cats may need coaxing to come out of hiding.
• Be sure to contact or visit surrounding shelters such as the Humane Society of Weld County, the Cheyenne Animal Shelter, the Longmont Humane Society or the Humane Society of Boulder Valley.

Larimer Humane Society is northern Colorado’s resource for lost and found pets. Each month, we reunite hundreds of worried pet owners with their stray companions.

If the animal you have found is wearing a license tag, call us at 970-226-3647 and we’ll trace the owner’s contact information.If the animal is not wearing an identification tag, you have three options:

1. File a Found Report and care for the animal until an owner can be located. To file a Found Report with Larimer Humane Society we will need to know the animal’s species, breed, color(s) approximate age, sex, tail length, approximate weight as well as where and when the animal was found. You are welcome to bring the animal to Larimer Humane Society so we can scan for a microchip (a permanent form of identification located under the animal’s skin) and accurately complete a found report.

   If you will be keeping the animal at your home, please place a Found ad in the newspaper, post fliers where the animal was found, and contact veterinarians and feed stores in your area. Most newspapers offer Found ads for free.

2. Bring the animal to Larimer Humane Society. The shelter is open seven days a week and no appointment is necessary. Click here for our hours and location . All stray dogs must be on leash and stray cats must be confined in a box or carrier when entering the animal shelter. Larimer Humane Society is the logical place for a owner to look for their lost pet. Stray animals not reclaimed by their owners after five days are evaluated for our adoption program.
3. Request Animal Control assistance for stray animal pick-up. Use this option if you are unable to transport a stray animal or if you feel the animal you have found may be a threat to people or other animals. An Animal Protection & Control Officer will respond to emergency calls 24-hours a day, but if possible (and safe), please confine the animal and call during business hours. Call 970-226-3647 to Larimer Animal Protection & Control.

Please note: time-sensitive correspondence such as Found Reports or requests for Animal Control assistance should not be sent via Email. Please contact Larimer Humane Society directly at 970-226-3647 or fax us at 970-226-2968.

Once you’ve found your pet, ensure his or her safety by

• Keeping a collar, license and identification tag on your pet at all times. Lost animals wearing identification are usually returned directly home.
• Microchiping your pet. Microchips are a painless, permanent form of identification. The inert microchip inserted under your pet’s skin is encoded with a number that is registered in a national database and can traced back to you, 24-hours a day.
• Keeping your cat indoors. Cats allowed to roam outside don’t live as long- it’s that simple. Consider building a safe enclosure for your cat or only allowing her outdoors when supervised. It’s especially important to confine your cat during early morning and evening hours when coyotes, foxes, and hawks are looking for prey.
• Having your pet spayed or neutered. Altered animals are less likely to roam from home and if they do, they don’t contribute to pet-overpopulation.
• Upgrading your cat's lifestyle! Indoor cats live longer, healthier lives. Welcome your feline friend into your home to show how much you care.
• Confining your dog. If your yard isn’t fenced, consider investing in a free-standing dog kennel. Tethering your dog is not a safe alternative and will not protect him from other aggressive dogs, wildlife, theft, or dangerous entanglement. If your dog is left alone each day, consider doggy day care or a neighborhood cooperative play group.
