Pet insurance is one of the few purchases where the cheapest option can be actively worse than none — because it creates a belief you are covered for things you are not.
The differences between policy types are the whole subject.
The four types
Lifetime. Covers a condition for the dog’s whole life, as long as you renew continuously without a gap. The annual limit resets each year.
This is the only type that properly covers chronic conditions — arthritis, diabetes, epilepsy, allergies, heart disease, inflammatory bowel disease. These are exactly the conditions that cost the most over time, and they are the reason insurance exists.
Most expensive, and for most people the only type worth buying.
Maximum benefit (per condition). A fixed sum per condition, with no time limit. When that sum is used up, the condition is excluded forever.
Workable for a one-off injury. Inadequate for anything chronic — a limit of a few thousand disappears in two years of managing a diabetic or epileptic dog, and then you are paying for the rest of their life.
Time-limited. Covers a condition for twelve months from the first sign or the first claim. After that it is excluded permanently, whether or not the money ran out.
Cheap, and effectively useless for chronic disease. A dog diagnosed with arthritis at eight is covered for one year of a condition they will have for the rest of their life.
Accident only. Covers injuries, not illness. The cheapest and the narrowest.
What to compare beyond the type
- Annual limit, and whether it is per condition or overall
- Excess — fixed amount, and whether it is per condition per year or per claim
- Co-payment, a percentage you pay on top of the excess. Very common in older dogs, and it can be 20 percent or more
- Whether the excess and co-payment increase with age — many do, sharply, from around eight
- Dental cover, which is frequently excluded or conditional on annual check-ups and treatment
- Complementary treatment — physiotherapy, hydrotherapy, acupuncture
- Behavioural treatment, which some policies cover if referred by a vet
- Third party liability — important, and legally required for some breeds in some countries
- Whether the vet can claim directly, which matters enormously in a large emergency claim
- Whether premiums rise with age, and by how much
Pre-existing conditions
The rule almost everyone learns the hard way: anything your dog has shown signs of before the policy starts, or during the waiting period, is excluded.
“Signs of” is broader than “diagnosed with”. A note in the clinical history about an itchy ear at eighteen months can support exclusion of allergic skin disease at four.
Consequences:
- Insure early, ideally as a puppy, before anything is on the record
- Switching insurers resets everything. Anything that has happened since the original policy started becomes pre-existing with the new insurer. This is why people stay with an expensive insurer rather than switching — and why comparing on price alone at renewal is a trap
- A gap in cover, even briefly, can be treated as a new policy
Breed and age
Breed loading. Some breeds cost considerably more, reflecting known conditions — brachycephalic breeds, large breeds with joint problems, breeds with high cancer rates.
Breed exclusions. Some policies exclude conditions known to be associated with a breed, such as brachycephalic airway syndrome in flat-faced dogs, or hip dysplasia in some large breeds. Read this carefully; it can gut the value of a policy.
Age limits. Many insurers will not start a new policy on a dog over a certain age, typically eight or nine. Existing lifetime policies continue, which is another argument for insuring early.
The alternative: self-insuring
Putting aside a fixed amount each month into a dedicated savings account.
Works if: you are disciplined, you start young, and you never touch it.
The problem: emergencies do not wait for the fund to grow. A cruciate ligament repair, a foreign body surgery, or a week of intensive care for a poisoning can run into thousands, and a dog can need that at eighteen months.
A reasonable compromise for people who dislike insurance: a lifetime policy with a high excess, which keeps premiums lower while covering the catastrophic end, combined with savings for routine costs.
Making a claim
- Tell your vet at the start that you intend to claim
- Ask whether they do direct claims. Many do for larger amounts, which means you pay only the excess
- Get the claim form started early rather than at the end of treatment
- Keep every invoice and receipt
- Read the exclusions before treatment starts, not after
Common reasons claims are refused
- Pre-existing conditions, including things noted but not diagnosed
- Preventive care — vaccinations, worming, flea treatment, neutering — which is almost never covered
- Conditions arising from failure to vaccinate or worm
- Dental disease where annual checks were not done
- Elective procedures
- Breeding-related costs
- Conditions specifically excluded for the breed
- Claims made after the policy’s reporting deadline
What it does not cover, almost universally
Routine preventive care, vaccinations, parasite treatment, neutering, grooming, food, and behavioural training that is not veterinary-referred.
Budget for these separately. They are predictable, which is precisely why they are not insured.
The realistic advice
- Insure as a puppy, before anything is on the clinical record
- Buy lifetime cover if you can afford it
- Read the exclusions, particularly breed-specific ones
- Understand the excess and any co-payment, including how they change with age
- Expect premiums to rise substantially as your dog ages, and budget for it
- Think very hard before switching insurers, because of pre-existing exclusions
- Keep the policy going without gaps
And have a number in mind — a realistic figure you could find in an emergency. Knowing it in advance makes the conversation in a consulting room at midnight considerably easier than working it out on the spot.
