Law in place — only officials may rescue
Leaving an animal unattended in a vehicle under dangerous conditions is an offence in Washington. Only officials such as police, animal control or firefighters are authorised to break in to rescue an animal; a bystander should call 911 rather than break a window.
Yes. Washington requires dogs, cats and ferrets to be vaccinated against rabies. Boosters follow the vaccine used (usually every 1 or 3 years).
What the law says: An owner of a dog, cat, or ferret shall have it vaccinated and revaccinated against rabies following veterinary and USDA-licensed rabies vaccine manufacturer instructions. This requirement does not apply to animal shelters. WAC 246-100-197
Yes — Washington bans breed-specific rules. Cities and counties may not ban or restrict a breed unless they meet strict conditions set in the law (including an exemption for dogs that pass a canine good citizen test).
Washington has a strict liability statute: the owner is liable for a bite even if the dog had never shown aggression before. Common defences are provocation and trespassing.
What it covers: Bite
Where: While in or on a public place or lawfully in or on a private place including the property of the owner of such dog
Defences: Police dog: This section does not apply to the lawful application of a police dog, as defined in RCW 4.24.410
Yes. Washington lets a court include pets in a domestic-violence protective order (since 2009) — for example by giving the petitioner care of the animal and ordering the abuser not to harm or take it.
Washington laws allows inclusion of pets in protective orders in cases of domestic abuse. Since amendments in 2009 to the original law, in addition to other forms of relief, a court may also order possession and use of essential personal effects. Personal effects may include pets. The court may order that a petitioner be granted the exclusive custody or control of any pet owned, possessed, leased, kept, or held by the petitioner, respondent, or minor child residing with either the petitioner or respondent and may prohibit the respondent from interfering with the petitioner's efforts to remove the pet. The court may also prohibit the respondent from knowingly coming within, or knowingly remaining within, a specified distance of specified locations where the pet is regularly found.
Partly. Since 2021 Washington pet stores may not start selling dogs or cats; stores that already sold dogs may continue under sourcing and disclosure rules, and lose the right after repeated violations.
Not for family pets travelling with their owner. A health certificate is required, but family pets with a current rabies certificate travelling by private vehicle with their owner are exempt. Pets 90 days and older need a rabies vaccination.
As summarised by the AKC (March 2023) — confirm with the state veterinarian before you travel:
CVI required.
CVI must identify each animal and certify the rabies vaccination is current and the animal does not originate from an area under quarantine.
Dogs 6 months of age or older may be required to be tested negative for heartworm.
Dogs that are family pets, have been owned more than one month, and are not going to be sold or have a change of ownership and are traveling by private conveyance with their owner or handler are exempt from the heartworm test requirement.
Dogs, cats or ferrets less than 90 days of age do not require a rabies vaccination.
Dogs, cats or ferrets that are family pets and have current rabies vaccination certificates and are traveling by private conveyance with their owners are exempt from the CVI requirement.
Washington has no statewide dog licensing requirement — counties and cities set their own. Most require a licence with proof of rabies vaccination, so check with your local animal services or clerk.
