Missouri Pet Limit Laws: How Many Pets Can You Own?

If you are wondering whether Missouri caps the number of pets per home, the short answer is no at the state level. The rules that matter are local, plus licensing rules for people who keep many dogs or breed them.

Missouri pet limit rules at a glance

What Missouri law says

• No Missouri statute caps household pets.
• Breeders with 3 or fewer intact females are exempt from the Animal Care Facilities Act (273.342).
• The Canine Cruelty Prevention Act does not limit the number of non-breeding dogs (273.345(6)).

Where pet limits usually come from

• City and county ordinances. Cities can cap household pets or require a kennel or multi-pet permit above a set number.
• Zoning rules. Keeping many animals can turn a home into a "kennel" use that is not allowed in residential zones.
• Leases and HOAs. Landlords and homeowners associations can set lower limits than the law, and many restrict size or breed.
• Nuisance and cruelty laws. Even without a number cap, barking, odor or poor care can lead to enforcement.

How to check the limit for your address

1. Search your city code for "animals" or "dogs" and look for a number limit or a kennel permit section.
2. If you live in an unincorporated area, check the county code instead.
3. Read your lease or HOA covenants.
4. Ask local animal services; they also sell dog licenses and can tell you whether a multi-dog or kennel license is needed.
