Adoption Process


STEP 1: Submit an application for an adoptable dog, cat, or bunny on our website. Applications remain on file for one year and can apply to any pet, so please do not resubmit additional applications. Please note that we have separate applications depending on the species of pet.

STEP 2: An Adoption Coordinator will respond to your application within 48-72 hours and let you know next steps.

STEP 3: If the pet you originally applied for was not a great fit, keep an eye out on the website for future matches! Your application will stay on file for one year and can apply to any pet (just email us when a new dog becomes of interest!) Please do not submit multiple applications.

ADOPTION CENTER: Our Adoption Center is open every Wednesday – Sunday in Bucktown. Our Adoption Center has adoptable dogs. Adoptable cats and bunnies live in foster homes. We work on a first come basis. We are limiting the amount of visitors on site, so you may be asked to be added to the waitlist when you arrive. Visitors must maintain distance from staff and wear a mask covering their nose and mouth during the duration of their visit. We require all family members of the household (including any resident dogs with current vaccination records) to be present at the introduction. We recommend being prepared to adopt same-day as the dogs at our Adoption Center are available for direct adoption and we do not “hold” them for specific applicants.

You can view which dogs are currently at our Adoption Center by selecting “adoption center” in the attributes tab on our Available Pets page.

ADOPTION APPOINTMENTS: For dogs, cats, bunnies, and guinea pigs living in foster care our Adoption Coordinator will set up adoption appointments with potential adopters after an application is submitted. We do not have cats, bunnies, or guinea pigs living at our Adoption Center (only dogs!)


Adoption fees include: Spay/neuter*, microchip, initial vaccines and a wellness exam.

* Due to limited appointment availability, some pets may be adopted out on a spay/neuter contract with a refundable $50 spay/neuter deposit which is reimbursed after the surgery is complete.

Dog Adoption Fees
Puppies under 6 months: $350
Adult Dogs: $300
Dogs 7 years and older: $150
*Senior humans that adopt senior dogs receive a special rate of $100.

One Tail requires adopters of puppies 6 months and under show proof of enrollment in a positive reinforcement training class within two weeks of adoption at the adopter’s expense.

Cat Adoption Fees
Kittens: $100
Adult Cats: $75

Adopters should be ready to take home their new dog or cat within 1-2 days of being matched. We do not ‘hold’ animals for any period of time. Please note cats and bunnies live in foster homes and are not eligible to meet at our Adoption Center.

Adopter Support Programs:

Dutch’s Fund

DUTCH’S FUND was created as a way for One Tail to care for dogs suffering from medical problems, or needing on-going treatment to remain healthy and happy.  Fund’s from Dutch’s Fund also help dogs that have already been adopted.  The DUTCH’S FUND GRANT allows One Tail adopters to apply for up to $500 in assistance in paying for unexpectedly large veterinary bills.  Email [email protected] for more information and to receive a grant application.

Stella’s Fund

STELLA’S FUND was created to assist adopters in need of financial assistance to pay for training. If a dog presents with a troubling behavior after the adoption and you need help getting training, please contact us. We will guide you to a trainer suited to your needs, and help you with training costs. Email [email protected] for more information and to receive a grant application.
