Summary

Any grooming shop or parlor operating in unincorporated St. Charles County must hold an annual kennel registration from the Division of Humane Services and pass a health inspection before opening. Parlors must strap animals during grooming so none can fall or be hanged, never leave a pet unattended before a dryer, and never cage more than one animal together.

These county ordinances apply to unincorporated areas of St. Charles County. Incorporated cities within the county may have their own rules that take precedence over county-level regulations.

A. Grooming parlors shall: 1. Provide such restraining straps for the animal while it is being groomed so that such animal shall neither fall nor be hanged. 2. Not leave animals unattended before a dryer. 3. Not prescribe or administer treatment or medicine that is the province of a licensed veterinarian. 4. Not put more than one (1) animal in each cage. 5. Provide for the removal and disposal of animal and food wastes, bedding, and debris. Disposal facilities shall be maintained in a sanitary condition, free from the infestation or contamination of insects or rodents or disease, and from obnoxious or foul odors.

Violations & Fines

Operating a grooming shop without a valid Division registration, or in violation of the sanitary standards in §205.210, is unlawful under §205.180(B) and is grounds for the Division to deny or revoke the registration outright. A cited parlor first receives a written notice of violation giving 10 days to correct the problem, followed by re-inspection within 3 days (§205.180(C)); if the violation is not corrected, the registration is revoked and the shop is closed, though the owner may appeal that revocation to the Department Director within 5 days of the notice (§205.180(D)).

Frequently Asked Questions

Do I need a county registration to run a dog grooming shop in unincorporated St. Charles County?

Yes. Section 205.160(A) makes it unlawful to keep or maintain a grooming shop without a valid registration from the Division of Humane Services, and each separate physical location needs its own registration. The fee is $50 a year, and you also need a written zoning-compliance statement before it's issued.

What are groomers prohibited from doing to animals?

Section 205.210(A) bars leaving an animal unattended in front of a dryer, prescribing or administering veterinary treatment, and putting more than one animal in a cage. Parlors must also use restraining straps so an animal being groomed can neither fall nor be hanged.

What happens if my grooming shop fails inspection?

The Division issues a written notice of violation giving you 10 days to fix the problem, then re-inspects within 3 days under §205.180(C). If it's still not fixed, the registration is revoked and the shop must close, though you can appeal that revocation to the Department Director within 5 days under §205.180(D).

Can a groomer give my pet medicine if it seems sick?

No. Section 205.210(A)(3) specifically bars grooming parlors from prescribing or administering treatment or medicine that is the province of a licensed veterinarian, so any medical issue found during grooming has to be referred out.
