Urgent but not immediately life-threatening Call before arrival so the team can advise whether to come in and what to expect at triage. Appetite, vomiting/diarrhea frequency, pain level, mobility, urination, breathing, and your regular vet’s name.
Specialty appointment Have your primary veterinarian submit a referral, then call Port City to schedule the initial visit. Referral reason, medical records, lab work, X-rays, ultrasound reports, medication list, and insurance details.
Pet is already admitted Use one designated family contact for updates and keep the phone available. Preferred phone numbers, medication questions, budget questions, discharge transportation, and recheck availability.

Google map, current address, and arrival checklist

Use the current official address below. Do not rely on old third-party listing addresses for an emergency trip.

Port City Veterinary Referral Hospital
231 Corporate Drive
Portsmouth, NH 03801
Main: 603-433-0056

Use this embedded Google map for route planning. If your pet is unstable, call 603-433-0056 before or during travel so the team knows what symptoms you are seeing.

Dogs

Use a secure leash and collar. If your dog is weak, painful, or unable to walk, ask whether staff can assist with a stretcher or safe entry plan.

Cats

Use a closed carrier. A stressed or injured cat can escape quickly in a parking lot, lobby, or exam room.

Toxin cases

Bring packaging, medication bottles, plant pieces, food wrappers, or a photo of the suspected toxin. Tell staff the time and possible amount eaten.

Records

Bring recent lab work, imaging, discharge notes, medication names, allergies, insurance documents, and your primary veterinarian’s contact details.

Emergency and urgent-care procedure at Port City

Port City provides emergency and critical care 24/7. Calling ahead helps the team prepare, but do not delay travel when symptoms are severe.

Call before arrival when possible. Use 603-433-0056. Tell the team your pet’s species, age, weight, symptoms, time symptoms started, medications, and whether breathing, walking, urination, or consciousness is affected.
Track symptom timing and frequency. For vomiting, diarrhea, seizures, breathing changes, coughing, collapse, or bleeding, write down when it started and how many times it happened.
Bring toxin evidence. If your pet ate something suspicious, bring the package, remaining item, bottle, label, or a clear photo. Honest details help the team treat faster.
Use safe transport. Dogs should have a leash and collar. Cats should be inside a carrier. If your pet is painful or cannot walk, ask staff about safe unloading.
Expect triage on arrival. A technician will evaluate the pet and decide whether immediate treatment is needed. A team member may ask for client registration and next-step instructions.
Emergency sign Why it matters What to do
Trouble breathing Breathing distress can worsen quickly and needs urgent oxygen or diagnostics. Call Port City and travel for emergency care immediately.
Bloat signs A distended abdomen, retching, and restlessness may signal a life-threatening gastrointestinal emergency. Go now; do not wait for a routine appointment.
Seizures Repeated or prolonged seizures can become dangerous. Track seizure length, keep your pet safe from injury, and call ahead.
Poisoning or toxin exposure Treatment depends on the product, amount, timing, and pet size. Bring packaging and call for guidance.
Trouble urinating Urinary blockage can be life-threatening, especially in male cats. Seek emergency care immediately.
Sudden weakness or inability to walk This can involve neurologic, cardiac, trauma, or severe pain causes. Call, transport safely, and avoid forcing movement.

How specialty appointments work

Specialty care is usually coordinated with your family veterinarian. Emergency care is available without a routine appointment, but call first when possible.

Referral visit
Your primary veterinarian typically sends a referral form that explains your pet’s problem and identifies the right specialty department.
Initial scheduling
After referral, call 603-433-0056 to schedule the initial specialty visit or confirm the next step.
Arrival for appointment
Park, proceed to the front desk, and wait for the team to confirm room availability or additional instructions.
Routine care boundary
Referral patients are treated for the referred condition. Routine vaccines, heartworm testing, and primary-care wellness work are not the purpose of referral visits.
Appointment call script: “My primary vet is referring my pet to Port City for __. The referral was sent on __. My pet is a __-year-old dog/cat. Current symptoms are __. What department should we schedule with, and what records should I bring?”

When your pet is admitted to Port City

Hospitalization can be stressful. These steps help families understand communication, treatment plans, updates, confidentiality, and discharge.

Before admission
The medical team will explain your pet’s condition and treatment plan. Ask questions about feeding, medications, monitoring, diagnostics, and expected decision points.
Treatment plan
Port City states that an itemized treatment plan is reviewed with owners. Ask which items are required, which are possible add-ons, and what changes may increase the estimate.
Medical updates
Hospitalized-patient updates are described as twice daily: morning between 6:00 am and 11:00 am, and evening between 3:00 pm and 7:00 pm. The team also calls for significant status changes.
Family contact
Designate one family member for medical updates and have that person relay information to others. This prevents missed or conflicting communication.
Confidentiality
Patient condition is treated as confidential. The hospital will discuss your pet with you or the designated person listed on the patient information sheet.
Discharge timing
Be prepared to spend up to one hour during discharge so the team can review instructions, medications, rechecks, balance, and safe home care.
Hospitalization notebook checklist: Write down the diagnosis, tests pending, medication names, feeding plan, overnight risks, next update window, estimate range, discharge criteria, recheck date, and emergency signs after discharge.

Payment, estimates, financing, and pet insurance

Emergency and specialty care can involve diagnostics, imaging, hospitalization, surgery, anesthesia, transfusions, oncology, or critical care. Review the estimate before services whenever possible.

Payment before services

Port City’s payment page states that, on the day services are rendered, owners are asked to pay the estimate in full before services are rendered.

Payment methods

Visible payment options include cash, personal checks with ID, major credit cards, CareCredit, and Scratchpay. Confirm current policy directly before arrival.

CareCredit and Scratchpay

CareCredit and Scratchpay are lines of credit handled by outside financial institutions. Port City can help with forms and receipts, but approval terms come from the lender.

Pet insurance

Insurance coverage varies by company and policy. Read deductible and reimbursement language carefully, including annual deductible versus per-incident deductible rules.

Before authorizing care Question to ask Why it helps
Estimate review What is included in the estimate, and what could make it increase? Helps you plan for hospitalization, imaging, surgery, medications, and rechecks.
Diagnostics Which tests are urgent tonight, and which can wait for the specialist? Clarifies the difference between stabilization and full workup.
Financing Can I apply for CareCredit or Scratchpay before drop-off? May reduce delays on the day of a scheduled procedure.
Insurance Can I receive an itemized invoice and medical records for my claim? Most pet insurance claims require invoices, diagnosis, and medical notes.

Forms, portal, records, and pharmacy routes

Use official forms and portals for paperwork, patient drop-off, client information, and referral communication. Call for urgent issues.

Client registration

Open client registration form

  1. Use before or during intake when requested.
  2. Have owner contact information ready.
  3. For emergencies, do not let paperwork delay urgent travel.

Patient drop-off form

Open patient drop-off form

  1. Use when Port City requests drop-off details.
  2. Include medication names, feeding instructions, symptoms, and current concerns.
  3. Ask whether your pet must fast before imaging, anesthesia, surgery, or sedated diagnostics.

Client portal

Open client portal

  1. Use for available account and patient information.
  2. Call directly for urgent medical concerns.
  3. Confirm the best route for records if another hospital needs them.

Compounded medication refill

Open compounding pharmacy page

  1. Use for species-specific formulations, delivery systems, or medication sizes.
  2. Request refills before medication runs out.
  3. Confirm whether the prescribing doctor must approve a refill or dose change.

First-aid PDF and poison-control preparation

Port City’s emergency page links to a pet first-aid kit checklist. Keep a kit in your car or home, especially if you travel with pets.

Emergency-prep item What to keep ready Pet owner note
Phone numbers Regular veterinarian, closest emergency room, and poison-control number. Port City lists ASPCA Animal Poison Control at 888-426-4435 and Pet Poison Helpline at 800-213-6680.
Transport basics Spare leash, carrier, blanket, disposable gloves, and muzzle. Only use a muzzle if it is safe; do not muzzle a pet that is vomiting or struggling to breathe.
Bandage basics Self-cling bandage, gauze pads, gauze roll, bandage tape, and cotton balls. Bandaging can worsen some wounds if too tight. Ask emergency staff for guidance.
Tools Scissors, tweezers, flashlight, saline solution, rectal thermometer, rubbing alcohol, and ice pack. Use rubbing alcohol to clean the thermometer, not as a wound treatment unless instructed.
Medication caution Diphenhydramine only if approved by a veterinarian. Do not give human medication without veterinary direction.
Paperwork Rabies certificate and important medical records. Digital copies help, but paper backup is useful during travel or phone battery failure.
Toxin call script: “My pet may have eaten __ at __ time. Pet weight is __. Amount may be __. Symptoms are __. I have the package with me. Should I come directly to Port City or call poison control first?”

Third-party listing gap audit

Maps and directory pages can be useful, but they often miss the practical information that matters during an emergency or referral appointment.

Common listing issue Why it can confuse pet owners What this guide adds
Old Commerce Way address Some older listings still show a prior location, which can waste time during an emergency. Current official address: 231 Corporate Drive, Portsmouth, NH 03801, plus embedded map.
Only phone and stars Ratings do not explain emergency triage, referral scope, forms, or hospitalized-patient updates. Call-ahead steps, arrival instructions, update windows, payment planning, and discharge checklist.
Generic “emergency vet” wording Owners may not know whether to call, what to bring, or how triage works. Life-threatening vs urgent workflow, toxin packaging steps, symptom tracking, and triage expectations.
Specialty list without use cases Owners may not know whether cardiology, internal medicine, surgery, oncology, imaging, or ophthalmology fits the case. Department-by-department table with symptoms, tests, and appointment questions.
Payment info missing Emergency and specialty care often requires estimate review and payment planning before services. Payment options, estimate questions, CareCredit/Scratchpay note, and insurance claim preparation.

Do not rely on online information for emergency triage. Breathing difficulty, poisoning, trauma, seizures, urinary blockage, bloat signs, severe pain, sudden collapse, or suspected toxin exposure needs immediate veterinary help.
