Summary
Idaho Falls requires dogs and cats adopted from the Animal Control Shelter to be spayed or neutered within 30 days, and imposes the same mandate on any unaltered dog or cat impounded twice within one year.
Any dog adopted from the Animal Control Shelter shall be spayed or neutered by a licensed veterinarian either prior to adoption, or within thirty
(30) days of adoption, or as soon after the dog is old enough to be spayed or neutered. If the dog is not already spayed or neutered, the adopter shall agree to provide evidence of spaying or neutering to the Animal Control Shelter within thirty (30) days. For dogs determined by a licensed veterinarian to be too young to be spayed or neutered within thirty (30) days of adoption, proof of spaying or neutering shall be provided by the dog's owner within thirty (30) days of the age the dog became eligible for spaying or neutering, which date shall be designated on the adoption paperwork.
(D) An unneutered dog that has been impounded at the Animal Control Shelter on two (2) previous occasions during the previous one (1) year period shall be required to be spayed or neutered prior to the owner redeeming the animal. The impound, and boarding fees, shall be applied toward the cost of the spay or neuter.
(E) Unclaimed Dogs. The ownership of any dog not redeemed within the periods of time herein stated shall be forfeited and the dog may be sold thereafter by the Animal Services Manager to any person.
(F) No dog shall be released from the Animal Control Shelter unless the dog is licensed
Full Breakdown
Idaho Falls City Code § 5-6-6(C) requires that any dog adopted from the Animal Control Shelter be spayed or neutered by a licensed veterinarian before adoption or within 30 days after, with proof due to the shelter within that window. Section 5-6-6(D) goes further: an unneutered dog impounded twice at the shelter within one year must be spayed or neutered before the owner may redeem it, with impound and boarding fees applied toward the surgery's cost. Sections 5-6-11(G)-(H) impose the identical 30-day and two-impound spay/neuter mandates on adopted and repeatedly impounded cats.
Violations & Fines
Failing to provide proof of spay or neuter within the required window can block redemption of an impounded, previously unaltered dog or cat until the surgery is completed; the animal's impound and boarding fees are applied toward the procedure's cost.
