New U.S. Pet Ownership Laws Taking Effect in 2026

Why 2026 Is a Turning Point for Pet Law in the U.S.

The United States leads the world in pet ownership, with the American Pet Products Association (APPA) estimating that roughly 67% of American households include at least one pet. With that scale comes growing legislative attention. In 2026, multiple states and the District of Columbia are enacting laws that significantly reshape the legal landscape for pet owners, renters, breeders, and veterinary professionals.

This guide covers the most important new U.S. pet ownership laws taking effect in 2026, organized by topic, with practical compliance advice tailored to American pet owners.

California's Statewide Cat Declawing Ban (AB 867)

Governor Gavin Newsom signed AB 867 into law, making California the first state to impose a comprehensive ban on elective cat declawing. Effective January 1, 2026, veterinarians in California may no longer perform onychectomy unless the procedure is medically necessary. When a medical exception applies, the veterinarian must document the justification, the alternatives that were considered, and why those alternatives were insufficient.

Declawing involves amputating the last bone of each toe. The American Association of Feline Practitioners (AAFP) has long discouraged the practice, noting that it can cause chronic pain, increased biting, litter box avoidance, and lasting behavioral changes. Before AB 867, only a handful of U.S. cities, including Los Angeles, San Francisco, Denver, and Austin, had enacted declawing bans. California's law sets a new statewide precedent that other legislatures may follow.

What cat owners should do: Owners concerned about scratching damage are encouraged to invest in scratching posts, nail caps (such as soft vinyl covers applied to claws), regular nail trimming every two to three weeks, and environmental enrichment. For indoor cats, maintaining a stimulating environment reduces stress related scratching. See our guide on Cat-Proof Windows and Balconies Without Blocking Airflow for additional ideas.

Disaster Abandonment: Florida's "Trooper's Law" and Beyond

Florida

Named after a dog found abandoned during a hurricane, Florida's "Trooper's Law" (effective October 1, 2025) is one of the strongest disaster related animal protection statutes in the country. Under this law, restraining a dog outdoors during a declared emergency and leaving the animal unattended is a third degree felony. This applies when a hurricane, tropical storm, or tornado warning has been issued, or when an area is under a mandatory or voluntary evacuation order.

Penalties are severe: up to five years in prison and fines reaching $10,000. Given Florida's exposure to hurricanes, typically from June through November, this law affects millions of pet owners across the state.

Washington State

Washington now requires emergency shelters established during wildfires, extreme temperature events, and other declared disasters to include provisions for animals. This is especially relevant in the Pacific Northwest, where wildfire seasons have grown more intense in recent years, with summer temperatures regularly exceeding 100°F in parts of eastern Washington.

Emergency planning tip: The Federal Emergency Management Agency (FEMA) and the American Red Cross both recommend assembling a pet emergency kit that includes at least three days of food and water, copies of veterinary records, current medications, a secure carrier, and up to date identification (microchip and collar tags). Our Memorial Day Dog Road Trip Checklist for U.S. Owners offers a useful framework for assembling a go bag that works for pets.

Puppy Mill Crackdowns: California Leads Again

California enacted three new consumer protection laws targeting the commercial pet trade, all effective January 1, 2026:

• AB 519: Prohibits both in person and online pet brokers from selling dogs, cats, or rabbits under one year old. The law also bans the sale of these animals in transient or outdoor public spaces such as parking lots, swap meets, and roadside locations.
• AB 506: Voids pet sale contracts that include nonrefundable deposits or fail to disclose the animal's medical history and breeder origin. If a contract is voided, the purchaser is entitled to a full refund and is not required to return the pet.
• SB 312: Requires dog importers to send health certificates to the buyer and the California Department of Food and Agriculture no more than 10 days before the dog enters the state.

These laws directly target what animal welfare advocates call the "puppy mill pipeline," where high volume commercial breeders in states with minimal oversight ship animals to markets with higher demand. The Humane Society of the United States (HSUS) has long advocated for these types of point of sale regulations. Buyers in any state should request a complete medical history and verify the breeder's USDA license number when purchasing from a commercial source.

Pet Rent Caps and Housing Protections

Washington, D.C.: Roscoe's Law

The "Pets in Housing Amendment Act of 2024," known as Roscoe's Law, is rolling out in two phases and represents the most comprehensive pet friendly housing legislation in the country. Named after Councilmember Robert White's late rescue dog (a pit bull mix), the law includes:

• Phase 1 (effective October 1, 2025): Pet security deposits are capped at 15% of monthly rent. Pet rent is capped at 1% of monthly rent per dog.
• Phase 2 (effective October 1, 2026): Landlords and housing providers that allow pets may no longer impose breed, weight, or size restrictions. Differential fees based on breed, size, or weight are also prohibited.

The law covers "common household pets" including domestic dogs, cats, small rodents, rabbits, and ferrets. For context, in a D.C. apartment renting at $2,000 per month, the maximum pet deposit under the new law would be $300, and monthly pet rent could not exceed $20 per dog.

Colorado

Colorado has enacted pet rent caps for state financed affordable housing, limiting pet rent to $35 per month or 1.5% of monthly rent, whichever is greater. Separately, Colorado now prohibits insurers from cancelling, refusing, or unreasonably increasing homeowner or tenant insurance policies solely based on a dog's breed, unless the specific animal has been declared dangerous by a court or animal control authority.

This is a significant development for owners of breeds commonly targeted by insurance restrictions, including American Pit Bull Terriers, Rottweilers, German Shepherds, Doberman Pinschers, and Akitas. Affected pet owners in Colorado should request written confirmation from their insurer that breed alone is no longer grounds for policy changes.

The Shift Away from Breed Specific Legislation

While some countries are expanding breed bans (the United Kingdom added the XL Bully to its banned list in 2024), the U.S. legislative trend is moving in the opposite direction. Both Colorado and Washington, D.C. are actively dismantling breed specific restrictions in housing and insurance. Multiple animal welfare organizations, including the American Veterinary Medical Association (AVMA), the ASPCA, and the National Canine Research Council, have stated that breed specific legislation is ineffective at reducing dog bite incidents and that behavior based assessments are a more reliable predictor of risk.

Pet owners in jurisdictions that still enforce breed specific ordinances should check with their city or county animal control office for current rules, as these can vary dramatically from one municipality to the next.

How U.S. Pet Owners Can Stay Compliant

• Monitor state and local legislation. Laws vary by state, county, and city. State legislature websites and local animal control offices are reliable sources of current rules.
• Maintain up to date veterinary records. Many new laws require documentation of medical history, vaccination status, and spay or neuter records. Rabies vaccination, required in all 50 states, should always be current. Average costs for a routine vet visit typically range from $50 to $300 depending on location and services.
• Review your lease carefully. Renters in jurisdictions with new pet rent caps or breed protections should review lease terms and, if necessary, request amendments to comply with updated local law.
• Build a pet emergency plan. Given the new felony penalties in Florida and shelter requirements in Washington State, every pet owner should have a documented evacuation plan that accounts for carriers, food, medications, and identification for each animal.
• Leverage technology. Digital tools can help track vaccination schedules, legal requirements, and pet health records. See our review of AI Pet Health Apps in 2026: Tools Ranked and Compared for current options.

When to Seek Professional Help

Legal questions about pet ownership, particularly those involving housing rights, breed restrictions, or disaster preparedness obligations, should be directed to an attorney familiar with animal law in the relevant state. The Animal Legal Defense Fund (ALDF) maintains a directory of attorneys and legal resources. Health concerns related to declawing alternatives, behavioral changes, or emergency medical needs should always involve a licensed veterinarian.

Pet sitting professionals and shelter volunteers working across state lines should consult our Spring Hazard Briefing Every U.S. Pet Sitter Needs for additional compliance considerations specific to multi state operations.

These legislative changes reflect a broader national shift toward stronger legal protections for animals. Staying informed is not merely a matter of avoiding penalties: it is a fundamental part of responsible pet ownership in the United States.
