Full Breakdown

Section 90.19 makes sterilization mandatory: no one may keep a cat over five months or a dog over six months that hasn't been spayed or neutered without a city-issued intact animal permit. RRARC grants permits for medical reasons (permanent or temporary), competition or show animals registered with a recognized club like AKC or the Cat Fanciers' Association, or function-bred working dogs with a documented pedigree or job history. Breeding an animal without a hobby breeder permit draws a $100 citation per litter under Section 90.20(B), and future breeding requires that permit regardless of intact-permit status.

Violations & Fines

Keeping an unaltered dog or cat without an intact animal permit is unlawful; breeding one without a hobby breeder permit draws a $100 citation for each litter produced.

Frequently Asked Questions

Can I keep an unaltered dog in Rio Rancho?
Yes, with an intact animal permit under Section 90.19(B) -- medical, competition/show, or function-bred exemptions qualify.
What if I breed my pet without a permit?
RRARC can cite you and fine $100 per litter under Section 90.20(B), and you'll need a hobby breeder permit before breeding again.
