If you have lost your pet, you should immediately file a Lost Report with the Montgomery County Animal Services and Adoption Center:

Online: An online lost report can be filled out at  Pet Harbor. On this site you will select to "Register to receive emails" from the Montgomery County Animal Services and Adoption Center (our shelter); you will receive daily email updates listing all pets found in your area that match your pet's description. Be sure that you are entering all descriptors in the proper field. Be sure to upload a recent photograph of your pet.

In person: Bring in a photograph if you have one available so that we can better match up your pet with the animals at the shelter. We are located at:

7315 Muncaster Mill Rd. 
Derwood, MD 20855

By phone:  (240) 773-5900 
Please call during open hours, and be prepared to give a detailed description of your animal. You should also be prepared to provide our customer service representative with a recent photograph of your pet, via email if possible.

• Visit the shelter at least every other day. Even if you have filed a report online or by phone and searched the database of stray animals, we recommend coming to the Center often to look for your pet.
• Contact other local shelters. For a listing of other shelters, visit  here.
• Check out other helpful online sites:

If you believe your lost pet is at our shelter you may call 240-773-5666 or come in person. Although closed for adoptions on Wednesdays, animals can still be reclaimed. Please be prepared to present at least one of the following items as proof of ownership*:

1. License and vaccination records
2. Purchase or adoption receipts
3. Microchip registration documents
4. Veterinary records
5. In cases where "next of kin" is reclaiming a pet:
   • Power of attorney

*Items should have name that corresponds with ID or photo identification.

If you have found an animal either bring it to the Center or, if you want to keep it in your house, file a found report with us. Many animals are reunited by matching up lost reports with found reports.

Online: An online found report can be filled out at  Pet Harbor.  Be sure that you are entering all descriptors in the proper field. Be sure to upload a photograph of the animal, if possible.

In person:  Bring in a photograph. Office staff will assist you with form completion.
