Municipal Experiences with Mandatory Spay/Neuter Laws

Where mandatory spay/neuter (MSN) laws have been introduced, they have failed to reduce euthanasia rates, have increased enforcement costs, and have decreased compliance with legally mandated licensing and rabies vaccination compliance:

San Mateo County, California – dog euthanasia rates increased by 126%, dog licenses declined by 35%

Los Angeles City, California – enforcement costs rose 269%, from $6.7 million to $18 million; and compliance to mandatory dog licensing declined

Fort Worth, TX -- ended its mandatory spay/neuter program. Rabies vaccination and licensing compliance declined after passage of the ordinance. This led to an increase in rabies in the city.

Montgomery County, MD – repealed its mandatory spay/neuter law. Euthanasia rates declined more slowly than they had been prior to the mandatory spay/neuter law; licensing compliance declined by 50%

King County, WA -- euthanasia rates fell at a slower rate after mandatory spay/neuter. License compliance has decreased. Animal control expenses have increased 56.8% and revenues only 43.2%

Camden County, NJ -- mandatory spay/neuter ordinance hasn’t stopped it from being called “consistently one of the leading, if not the leading killers of animals in the state of New Jersey” (ref: PAWS NJ)

Aurora, CO – euthanasia and shelter intake rates increased. Licensing compliance dropped dramatically, compliance costs have increased 75% with revenue increasing only 13% in unincorporated areas of the county which are the areas covered by the ordinance.
