Full Breakdown

County Code Chapter 4 regulates pet stores as "retail dog outlets": any premises selling dogs at retail. Owners must obtain an annual license from the County ($75, due March 1) and pass Animal Control inspections covering shelter, temperature, ventilation, sanitation, and enclosure-size standards for humane handling of dogs. There is no outright sales ban or adoption-only mandate. Separately, Sec. 4.02.005 bars selling or transferring any puppy under seven weeks old, with a narrow exception for orphaned puppies moved through a licensed shelter with veterinary sign-off.

Violations & Fines

Operating an unlicensed retail dog outlet, or a licensing violation, draws a $50-$100 fine (first offense), rising to $100-$200 for repeats. Failing to fix a cited care-standard deficiency after a 10-business-day warning draws $50-$100 (first) to $250 (repeat) and can trigger license suspension and dog seizure.
