A dog surrendered Monday morning might need a foster home by Friday. Most shelters and rescues don't have one lined up, and that gap is where good animals end up stuck in kennels longer than they should. A strong foster program closes that gap. 

It gets pets out of stressful shelter conditions faster, frees up space for the next intake, and gives animals one-on-one attention they can't get in a crowded facility.

The hard part isn't believing in foster care. It's building a system that recruits the right people, keeps them engaged, and turns them into repeat volunteers instead of one-time helpers.

Recruiting Foster Families Who Stick Around

Most shelters recruit the same way: a flyer at the front desk and a post on Facebook. That reaches people who already follow you. It rarely reaches the vet clinic client down the street, who's never heard of your program.

A few channels work harder than a single flyer:

• Vet clinics and pet stores. Postcards placed at checkout or mailed to local pet owners put your program in front of people who already care about animals.
• Social media stories. A photo and a two-line story about a specific foster dog outperforms a generic "we need fosters" post every time.
• Meet-and-greet events. Give people a low-pressure way to ask questions before they commit to bringing an animal home.

Positive Impressions works with shelters and rescues across the country to put postcards and mailers in front of the right audience, timed around adoption events or seasonal intake spikes.

Onboarding: The Step Most Programs Skip

Recruiting a foster is only step one. Programs lose volunteers fast when the first few weeks feel disorganized. A new foster who doesn't know who to call about a vet visit, or what supplies the shelter provides, is a foster who won't sign up again.

A simple onboarding packet fixes most of this: a welcome card, a one-page FAQ, and a direct phone number for questions. Pair new fosters with someone who's done it before if you have the volunteer base for it. That mentor relationship answers the small questions before they become reasons to quit.

Keep Fosters in the Loop

Foster families who feel forgotten stop fostering. Regular check-ins matter more than any single recruitment push, because retaining one experienced foster is cheaper than recruiting three new ones.

Email works for routine updates. But a handwritten-style postcard, sent mid-foster to ask how things are going, lands differently than another email in a crowded inbox. It's a small gesture that tells a volunteer their time matters to a real person, not just a database.

Use the same tool to remind fosters about upcoming vet appointments, training sessions, or adoption events. A physical reminder in the mail cuts through in a way a fourth calendar notification doesn't.

Say Thank You Before You Need Another Favor

Appreciation shouldn't wait until you need a favor. A thank-you card after a successful foster placement, a shoutout on your shelter's social page, or a small discount from a partner pet store all signal the same thing: this program values the people in it.

Shelters that build appreciation into their process see fosters return for a second and third placement instead of fostering once and disappearing. That repeat participation is what turns a foster list into a reliable program instead of a constant recruitment cycle.

Build Your Foster Program's Communication Kit

A foster program runs on more than good intentions. It needs a communication system: postcards for recruitment, welcome cards for onboarding, and thank-you cards for retention. 

Positive Impressions designs and prints these materials specifically for animal welfare organizations, so your program has a consistent, professional look at every stage of the foster relationship. Browse our foster and shelter product line to see options built for exactly this.

FAQs

How many foster families does a small rescue actually need to get started? Five to ten reliable families is enough to launch a small program. Start there, prove the system works, then grow recruitment as your process gets tighter.

What should go in a foster welcome packet? A direct contact number, a supply list, a basic care guide for the type of animal being fostered, and a welcome card that sets a warm tone from day one.

How often should we check in with foster families? Once a week for the first month, then every two weeks once the placement is stable. More frequent contact early prevents small problems from becoming reasons someone quits.

Do postcards still work for recruiting fosters in a digital-first world? Yes. Postcards get noticed precisely because most outreach today is digital. A mailed card at a vet clinic or pet store reaches people who won't see a Facebook post.

What's the real difference between a foster program and an adoption program? Adoption is permanent. Fostering is temporary care, usually until an animal is healthy, trained, or matched with a permanent home. Many people who can't commit to adoption become long-term fosters instead.
