How do you get a dog license in Portland, Oregon?
You must license your dog with Multnomah County Animal Services within 30 days of the dog turning six months old or within 30 days of moving into the county. Licenses are valid for one, two, or three years and require proof of a current rabies vaccination (Multnomah County Animal Services, retrieved 2026-06-13).
Fees depend on whether the dog is spayed or neutered, and seniors aged 65+ pay half. A $10 late fee applies if you miss the renewal deadline.
| License Type | 1 Year | 2 Years | 3 Years |
|---|---|---|---|
| Spayed/Neutered Dog | $27 | $47 | $62 |
| Intact Dog | $42 | $77 | $107 |
| Senior (65+) Discount | 50% off any tier above | ||
| Late Renewal Fee | $10 added to renewal | ||
Your dog must wear the license tag whenever it’s outside your home or yard. The only exception is when the dog is confined to your premises.
What are Portland’s leash laws?
Portland requires every dog in public to be on a leash no longer than eight feet, under Multnomah County Code Chapter 13 (Multnomah County, retrieved 2026-06-13). The rule applies to sidewalks, streets, parks (outside fenced off-leash areas), and any other public space. Violations are punishable by a fine of up to $150.
The leash law covers more than just walks. It applies any time your dog is in a public place, including transit stops, business parking lots, and shared apartment grounds. The only public spaces where a dog can be off-leash are the fenced Dog Off-Leash Areas (DOLAs) maintained by Portland Parks & Recreation.
If your dog injures someone while off-leash in a public area, the leash-law violation can be used as evidence of negligence in a civil case. Our Portland dog bite lawyers have seen leash violations cited in nearly every claim we handle.
What are the rules for off-leash dog parks in Portland?
Portland’s fenced Dog Off-Leash Areas (DOLAs) cap each handler at three dogs and require proof of license and vaccination on the dog’s collar (Portland Parks & Recreation, retrieved 2026-06-13). Violating posted DOLA rules can get you cited and removed from the park.
Common DOLA rules include:
- Limit of three dogs per person in the off-leash area
- Bring a leash and waste bag for each dog
- Display current license and vaccination tags
- Keep the dog leashed when entering and exiting the gated area
- Maintain voice or hand control at all times
- No food (human or canine) inside the fenced DOLA
- No digging — fill in any holes your dog creates
- Owners are civilly liable for damage or injury their dog causes inside the park
Portland has dozens of DOLAs across the city. Find the closest one through the Portland Parks dog parks directory.
What are a Portland dog owner’s responsibilities?
Portland and Multnomah County require dog owners to provide shelter, food, water, veterinary care, and humane treatment, mirroring Oregon’s animal welfare statutes under ORS 167.310 to 167.351 (Oregon Humane Society, retrieved 2026-06-13). Failure to meet these duties can result in animal-neglect charges and seizure of the dog.
Specific owner responsibilities under Multnomah County Code include:
- Provide adequate shelter, food, and clean water
- Clean up after your dog in public spaces (the “scoop law”)
- Provide veterinary care for illness or injury
- Prevent persistent barking, howling, or other noise that disturbs neighbors
- Keep the dog leashed and under control in public
- Maintain current rabies vaccination
- Renew the county license on time
What are the fines for breaking Portland’s dog laws?
Penalties for violating Portland’s dog ordinances range from $10 for noise complaints to $1,000 for an unprovoked dog attack, under Multnomah County Code Chapter 13 (Multnomah County, retrieved 2026-06-13). Repeat offenders can face higher fines, community service, and dangerous-dog designation.
| Violation | Fine | Additional Penalty |
|---|---|---|
| Leash law violation | Up to $150 | — |
| Scoop law violation | Up to $250 | Or 25-50 hours community service |
| Dog at large | $75 – $500 | Possible impoundment |
| Habitual barking / howling | $10 – $100 | Possible nuisance designation |
| Dog attack on person, animal, or property | $500 – $1,000 | Owner pays medical & veterinary expenses |
Fines are charged to the registered owner, not the handler walking the dog at the time. If your child or a friend was walking your dog when the violation occurred, you still get the citation.
What is Oregon’s dog bite law?
Oregon imposes strict liability on dog owners for a bite victim’s economic damages, including medical bills, lost wages, and property loss, under ORS 31.360. The victim does not have to prove the owner was careless — owning the dog is enough to trigger liability for those out-of-pocket losses.
For non-economic damages (pain and suffering, emotional distress, scarring), Oregon follows the older common-law “one bite” rule. The victim must show one of the following:
- The owner knew or should have known the dog was dangerous (prior bite, growling, posted warnings)
- The owner was negligent in controlling the dog (off-leash in violation of Portland’s leash law, gate left open, dog left with a child unsupervised)
- The owner violated a leash or containment ordinance, which can serve as negligence per se
Oregon’s statute of limitations for a dog bite injury is two years from the date of the bite, under ORS 12.110. Miss the deadline and you lose the right to recover, no matter how clear the liability.
If the bite happened on city or county property (such as a DOLA), a separate 180-day tort claim notice under ORS 30.275 may apply. Our Portland dog bite attorneys can confirm which deadlines apply to your case.
Does Portland have breed-specific dog laws?
Portland does not ban or restrict any specific dog breed. Multnomah County instead uses a behavior-based “potentially dangerous dog” designation under ORS 609.035 to 609.190 (Oregon Humane Society, retrieved 2026-06-13). Any breed can be classified as potentially dangerous after a single incident.
A dog can be designated potentially dangerous if it:
- Menaces or chases a person off the owner’s property without provocation
- Injures another animal without provocation
- Has a history of acts that justify the designation
Once a dog is designated, the owner must keep it confined, post warning signs, carry liability insurance, and notify Multnomah County of any move or change of ownership. A second incident can elevate the dog to “dangerous” status, which can require euthanasia in serious cases.
What should you do if a dog bites you in Portland?
Get medical attention first, then report the bite to Multnomah County Animal Services within 24 hours. Oregon law treats a dog bite that breaks the skin as a reportable incident, and the report creates an official record needed for an insurance or civil claim (Multnomah County Animal Services).
Steps to take after a dog bite in Portland:
- Get medical care immediately. Even a small puncture can cause infection. Save discharge papers and bills.
- Get the owner’s contact information and the dog’s rabies vaccination record.
- Photograph the wound, your torn clothing, and the location of the bite.
- Identify witnesses and get their phone numbers.
- Report the bite to Multnomah County Animal Services (503-988-7387) within 24 hours.
- Contact a Portland dog bite attorney before talking to the owner’s insurance company.
The owner’s homeowner’s or renter’s insurance usually covers dog bite claims. According to the Insurance Information Institute, the average dog bite claim paid in the U.S. was about $58,545 in 2023. Oregon’s average tracks close to that figure.
