To arrange a necropsy for a dog or cat, start with your veterinarian and the receiving laboratory before transporting the body. Confirm acceptance, who can submit, the arrival time, and storage instructions. Prompt refrigeration is commonly advised, but freezing rules differ. Send the medical history, agree on testing costs, and record the choice for the remains before the examination. Minnesota submission guidance; Missouri submission guidance.

A necropsy is a veterinary postmortem examination that may help explain an unexpected death. It cannot promise a definite answer. This guide compares named U.S. services and provides a question sheet for the intake call. Their policies are examples, so ask the laboratory handling your pet to confirm the instructions that apply to this case.

Use this question sheet before arranging transport

Keep one written record of the answers and share it with the clinic and whoever will deliver the body. The questions below bring together requirements from the cited submission forms and laboratory guidance. They are a planning aid, not a replacement for the receiving service’s authorization. Leave an answer marked as unconfirmed when you have not received it; another laboratory’s website cannot fill that gap.

Give the laboratory the actual timeline: when the pet died, how the body has been stored, and when arrival is possible. Ask the staff member to distinguish a drop-off window from an examination time. If anything changes before departure, such as a delayed courier or a new exposure concern, contact the service again rather than assuming the earlier arrangements still fit.

Confirm acceptance and who can submit

Owner submission is not handled the same way everywhere. Illinois directs animal owners to their local veterinarian. New Jersey strongly encourages that route. ViTALS at Virginia Tech requires authorization and submission through a veterinarian, except for owners living within 35 miles of the veterinary college. Necropsy Services Group, a private California service, accepts owner requests with prior coordination. These are institutional access rules, not a nationwide rule that owners either can or cannot request an examination. Illinois ordering guide; New Jersey policy; ViTALS guidance; Private service guidance.

Your veterinarian can help organize the history, state the diagnostic question, and interpret the report. Ask who will be the laboratory’s client and main contact, who can approve further charges, and who will update the family. Having an owner deliver the body does not, by itself, settle who must authorize the submission or receive the results. Confirm those roles separately.

A diagnostic laboratory is not automatically a walk-in hospital. Illinois, New Jersey, and Missouri do not accept live dogs or cats for necropsy. Cornell’s form requires prior arrangements for live-animal submissions. If the pet is alive or you are uncertain whether death has occurred, contact a veterinarian for care rather than treating the situation as a routine laboratory delivery. Missouri acceptance policy; Cornell submission form.

Check weekends and holidays explicitly. New Jersey lists a 1 p.m. Friday cutoff, or Thursday when Friday is a state holiday; later submissions wait refrigerated until the next business day. Illinois charges $100 for after-hours drop-off requiring an on-site pathologist. TVMDL lists 24-hour specimen lockers at College Station and Canyon for submissions smaller than 50 pounds. Locker access does not mean the examination happens immediately. New Jersey intake schedule; Illinois after-hours terms; TVMDL service listing.

Storage: ask about the delay before choosing to freeze

The practical priority is to preserve diagnostic value while you make arrangements. Minnesota prefers the whole animal submitted promptly and advises keeping it cold, but not frozen, if there is a delay. Missouri also advises prompt examination and refrigeration when feasible. Ask your clinic whether it can arrange suitable storage, especially when the pet is too large for the refrigeration available to you. Minnesota preservation guidance; Missouri preservation guidance.

Freezing is not a universal prohibition or a universal solution. It can create changes that make tissue interpretation harder, but a long delay without adequate cooling also limits the examination. Do not treat a general online time limit as a guarantee of preservation or as proof that an examination is no longer worthwhile. Describe the storage history and let the receiving pathologist assess what may still be learned.

These differences are real. UConn’s 48-hour instruction belongs to UConn; it is not a deadline adopted by every service. Likewise, the private service’s advice about larger dogs does not establish a general weight threshold for freezing. Tell the laboratory about any previous freezing and ask what to do next. Cornell’s form specifically asks whether the body was previously frozen. UConn storage instructions; ViTALS storage instructions; Private service storage advice; Cornell history fields.

Have the clinic or laboratory guide transport arrangements. Published guidance commonly calls for secure leakproof containment, cooling packs, protected paperwork, and a sturdy insulated outer container. UConn advises gel packs rather than wet ice for long transport. Obtain the receiving service’s current packing, labeling, carrier, and delivery-day instructions before shipping; a description of packaging alone does not establish that a shipment is accepted or properly classified. UConn transport advice; TVMDL packing guidance.

Send the history and a clear diagnostic question

The medical history helps the pathologist connect findings with what happened before death. Minnesota says a complete history is most helpful when written by the attending veterinarian. Missouri requests clinical signs and treatments or drugs given before death. ViTALS asks for treatments, vaccinations including rabies, and suspected causes. Ask the clinic to send existing records and identify gaps, rather than trying to reconstruct a medical explanation yourself. Minnesota history guidance; Missouri history requirements; ViTALS history requirements.

• Identification: species, breed, age, sex, weight, and the pet’s identifier on the records.

• Timeline: onset and duration of illness, major changes, and the known or estimated date and time of death.

• Circumstances: whether death was spontaneous or followed euthanasia; obtain the method from the treating clinic.

• Clinical information: signs observed, treatments and medications, vaccination dates, and relevant previous laboratory records.

• Main question: what the owner and veterinarian hope the examination can clarify, with suspected causes clearly labeled as suspicions.

Separate observations from assumptions. For example, record when the pet was last seen behaving normally and when collapse was noticed, rather than stating that an unconfirmed disease caused death. Mark an uncertain time as an estimate. Include the names of clinics holding relevant records so the submitting veterinarian can request them. This gives the laboratory a usable sequence without turning incomplete memories into established findings.

Agree on examination scope, consent, and the bill

Read the receiving laboratory’s forms before authorizing the examination. New Jersey requires both a completed general submission form and an animal submission acknowledgement before proceeding. Ask what each signature authorizes, whether the service is gross examination only or includes microscopy, and how extra tests will be approved. A gross examination looks at visible findings; histopathology evaluates tissues microscopically. The laboratory should explain which service best addresses the question you are asking. New Jersey authorization requirements; Cornell pathology services.

Keep the base examination fee separate from the allowance for ancillary testing. Cornell’s form offers advance ancillary-testing estimates of $100, $200, $500, another amount, or none. Illinois’s workup levels add actual ancillary-test costs to its $260 gross-and-histopathology base, with $250 or $500 ancillary ceilings. Those ceilings are not the total necropsy price. Confirm who must be contacted if more testing is proposed. Cornell authorization options; Illinois workup pricing.

These are named-laboratory list prices checked on October 22, 2026, not a national average or a complete owner estimate. Ask about clinic coordination, transport, disposal, cremation, and other applicable charges before agreeing. Illinois notes that a veterinarian’s bill can exceed the laboratory price because it also reflects professional time and related expenses. A lower listed base fee may cover less diagnostic work. Illinois fee explanation; TVMDL listed price.

Ask about specimen ownership and permitted uses, too. Cornell states that submitted samples become laboratory property and may be used for surveillance and research; New Jersey also takes ownership of submitted remains and specimens. Read the specific terms. Neither policy establishes that every laboratory performs every surveillance test, or that consent everywhere has identical terms. Cornell specimen terms; New Jersey specimen terms.

Choose what happens to the remains before submission

Ask about aftercare while arranging acceptance, even if you have not yet chosen a cremation provider. Confirm whether the body can be released, who may collect it, and whether any ashes can be returned. Record the selected option on the required form. A laboratory’s willingness to examine the pet does not imply that every burial or cremation choice remains available afterward.

These examples come from the linked forms and service policies. Do not infer an unlisted service’s arrangements from this table. Ask whether the estimate includes private cremation and return charges, who contacts the crematorium, and where the family will collect or receive the cremains. If the chosen option is unavailable, resolve that before signing rather than assuming a later transfer can be arranged. Cornell disposition choices; ViTALS disposition choices; New Jersey remains policy; TVMDL cremation hold.

Disclose rabies, insurance, and legal concerns up front

Rabies testing requires a qualified laboratory and a distinct assessment of possible exposure. CDC states that there is no approved method to diagnose rabies in a living animal; diagnostic testing for animal rabies is postmortem. Typical U.S. results are available 24–72 hours after the specimen reaches the laboratory. That timing is not a reason to postpone urgent medical advice for a person who may have been exposed. CDC animal testing guidance.

Let the veterinarian and public health authorities determine the route. A bite history does not by itself establish rabies, and neurological signs can have other causes. At UConn, cases involving possible human exposure have specific public-health arrangements; a complete necropsy arranged under those circumstances waits until rabies is excluded. Ask about any effect on aftercare as well: New Jersey restricts release of remains confirmed to have specified zoonotic infections. UConn rabies routing; New Jersey release restrictions.

Also declare insurance claims, suspected cruelty, or potential legal disputes before the examination. Ask whether the service accepts the case and what documentation it needs. ViTALS requests an insurance/legal flag. Cornell directs animal-crime investigations to a separate forensic form. TVMDL adds processing charges and time for legal or insurance documentation and does not perform forensic necropsies. New Jersey restricts forensic work to law enforcement and requests advance contact about legal or insurance aspects. ViTALS case flags; Cornell forensic form direction; TVMDL documentation limits; New Jersey case restrictions.

An insurance-related request does not automatically make the examination a forensic proceeding. A laboratory’s documentation fee also does not establish that an insurer covers the examination. Confirm claim requirements with the insurer and acceptance requirements with the laboratory. If the requested documentation exceeds what that service offers, ask about referral before proceeding.

Plan for reports, uncertainty, and follow-up

Ask separately about preliminary findings, microscopic evaluation, and the final report. TVMDL lists gross results within 1–4 days of receipt and notes that extra testing may take longer. Necropsy Services Group usually sends an initial written report within about a week; microscopy may take 3–6 weeks or longer. These are service-specific expectations, not a universal reporting schedule. TVMDL turnaround; Private service reporting times.

Clarify who will receive and explain the report. Cornell sends results to the submitting veterinarian, who informs the owner. Agree on a follow-up contact before submission. Ask whether the report explains a likely cause, identifies contributing findings, or remains inconclusive, and whether additional tests could answer the remaining question. Avoid reading an isolated technical term as the final explanation without that discussion. Cornell reporting terms.

Ask about sample-retention deadlines early. TVMDL retains fresh tissue for 14 days from receipt and requires further test requests within that period. That clock starts at receipt, so ask about additional testing while waiting for later reports. Other laboratories may keep different material for different periods; confirm their deadlines and whether the material needed for a proposed test is still available. TVMDL retention window.

Even a carefully arranged examination can remain inconclusive. Body condition, the nature of the death, and examination scope affect what can be learned. For example, Necropsy Services Group explains that some arrhythmias and metabolic disturbances may leave no detectable trace. Ask the pathologist or submitting veterinarian what the findings support and what remains uncertain. No result should be promised before the case is examined. Private service diagnostic limits.

Support can run alongside the investigation. Cornell’s pet-loss resource page lists a hotline staffed by veterinary student volunteers trained with grief counselors; its hours vary seasonally, and it is not a mental-health hotline. You can ask the veterinary team for support resources while practical decisions are being made. The decision to request or decline a necropsy need not be treated as a measure of how much you cared for your pet. Cornell pet-loss support.
