Summary
Pueblo doesn't require pet owners citywide to alter their animals, but under § 11-4-16(c) any animal adopted from the Pueblo Animal Shelter must be spayed or neutered before release, or the adopter must agree to do it within 30 days.
Upon adoption of any animal eligible for adoption from the Shelter Operator, and payment of the adoption fee therefor, the animal shall be either spayed or neutered by a licensed veterinarian at the animal shelter or the person adopting the animal shall execute a written agreement that the animal will be spayed or neutered within thirty (30) days of adoption and release. No animal adopted from the animal shelter shall be released without first having been spayed or neutered or before the written agreement is filed with the Shelter Operator.

Full Breakdown
Pueblo has no general mandate that pet owners spay or neuter their animals: that requirement only kicks in at the city shelter. Under § 11-4-16(c), an animal adopted from the Pueblo Animal Shelter must be spayed or neutered by a licensed vet before release, or the adopter must sign a written agreement to do it within 30 days and file proof of the procedure with the Shelter Operator afterward. No animal leaves the shelter without one or the other in place.
Violations & Fines
Signing an adoption spay/neuter agreement and then failing to complete the procedure, or failing to file proof within 30 days, is a Class 2 municipal offense under § 11-4-16(c)(2).
