Post-Adoption Support

You adopted a pet! Now what? This is your one-stop shop for all things post-adoption at Oregon Humane Society.

Here you’ll find adoption support resources, perks included with your adoption, and more.

Post-Adoption Resources

Introductory Period 

The shelter can be a stressful place for pets. You may see your new pet’s behavior change over the course of the next few months once you get home. The best thing to do is spend a few days just hanging out at home getting to know each other.

Introduction Guides

Post-Spay/Neuter Surgery

If your pet was spayed/neutered at OHS, you will want to wait at least 10 days prior to bathing. We use a surgical glue to close the incision and it is important to keep that area clean and dry. If your pet goes out in the rain, pat the area dry with a dry cloth. If you notice any redness or swelling at the incision site, please call OHS medical staff at (503) 285-7722.

Kennel Cough

All OHS puppies/dogs are vaccinated against kennel cough with the Bordetella vaccine. Vaccinated puppies/dogs can still come down with kennel cough. It is one of the most common shelter illnesses. Symptoms include a dry, hacking/honking cough, yellow-green nasal discharge, ocular discharge, sneezing and lethargy. If you notice the above symptoms, please contact your veterinarian as it is highly contagious.


Parvovirus and distemper are both gastrointestinal diseases that OHS vaccinates against with the DA2PP vaccine. Symptoms to look out for include vomiting, bloody diarrhea and lethargy. If you notice the above symptoms, please contact your veterinarian immediately. If your pet is diagnosed with parvo or distemper, please call OHS medical staff at (503) 285-7722.

Upper Respiratory Infection

URI, or upper respiratory infection, in cats is very similar to a common cold in humans. OHS cats/kittens are vaccinated against URI, as well as other diseases, with the FVRCP vaccine. Symptoms include sneezing, runny nose, red/runny eyes, fever, sores on tongue/lips/nose, lack of appetite and lethargy. If you notice any of the above symptoms, please contact your veterinarian.


Also known as feline distemper, panleukopenia is a rare but infectious viral disease in cats. Symptoms include vomiting, diarrhea, lethargy, lack of appetite and sudden death. The disease strikes suddenly and progresses rapidly, so if you see any of the above symptoms, please contact your veterinarian immediately. If your pet is diagnosed with panleukopenia, please call OHS medical staff at (503) 285-7722.

Feline Leukemia and Feline Immunodeficiency Virus

Feline Leukemia, also known as FeLV, is a virus that can cause a weakened immune system and result in diseases that are serious or can be fatal. Similarly, Feline Immunodeficiency Virus, or FIV, affects the immune system but is only transmitted through bite wounds. We recommend that all newly adopted cats and kittens be seen by your veterinarian and follow their recommendation for FeLV / FIV testing after adoption. Due to the very low instance of FeLV in our community, OHS does not test all cats prior to adoption. A test for FeLV and FIV is available for a $40 fee.


All puppies/dogs and kittens/cats transferred from out-of-state that are at least 3 months of age will be given a rabies vaccine.

You are required to license your new pet within 30 days of adoption. Click the links below for information specific to your county.


If your pet was spayed or neutered at OHS and you have concerns about the surgery site, please call (503) 285-7722.

Perks of Adopting from OHS

Veterinary Care

Prior to adoption from OHS, all pets are spayed/neutered, and receive initial vaccinations and a microchip.


All pets microchipped at OHS will be implanted with a HomeAgain microchip. Some animals transported through our Second Chance program will already be microchipped with a different brand, which can be found in your adoption receipt. Click the links below to register your microchip.

When you adopt a pet from OHS, you will receive one free veterinary exam at participating clinics within 10 days of adoption. You will find your new pet’s medical information inside the “receipt” attached to your adoption email. Bring these records, along with your 10-day Health Exam Certificate, to your vet. Be sure to call ahead of time to ensure they are accepting the certificate.

Community Veterinary Hospital

Did you know that OHS has a Community Veterinary Hospital next to the Portland campus? Your new pet can get continuity of care (and a free exam within 10 days of adoption) with our highly-skilled veterinary team, who are all trained in the same Fear-Free techniques as our shelter staff. Learn more about our preventative, dental, and urgent care services.
