As of 13 August 2026, AI can calculate the cost of owning a dog in the UK.

What to actually do

1. Use a tool built for this

   The route this page recommends

2. Do it yourself

   Second choice

   A chat interface, no skill needed, and roughly 30 minutes until you can act on the result.

   How to actually do it

   1. Write down the dog's age, breed or expected adult size, UK location, health needs, exercise routine and how long it will be left alone.
   2. Gather current UK prices or quotes for food, insurance, routine vet care, vaccinations, parasite treatment, grooming, training, walking, boarding and equipment, and record where each figure came from.
   3. Open a chatbot and paste the full prompt with your dog details, prices, links and household budget, then ask it to produce the categorised table and scenarios.
   4. Copy the model's input table into a spreadsheet and check that each monthly, annual and first-year total follows from the supplied figures.
   5. Open the original retailer, insurer, vet, groomer, boarding, walking and training pages and compare each drafted input with the current price, eligibility and location conditions.
   6. Add prices for any items the model marked "price needed", rerun the calculation, and compare the resulting recurring total with the amount your household can afford.
   7. Save the final table with its sources and assumptions, then use it as a budget rather than as a guarantee of future veterinary or emergency costs.

   Prompt

   Calculate the likely cost of owning a dog in the UK using only the information and prices I provide below. Do not invent prices, claim that a price is current, or fill gaps with an unsupported estimate. Separate one-off costs, regular costs, occasional costs and emergency or contingency costs. Show monthly, annual and first-year totals where the supplied figures allow it, and label every assumption. If a cost is missing, write "price needed" and tell me what to look up. Include separate low, typical and high scenarios only when I provide figures that support them. Account for the dog's age, size, location, health, exercise needs, insurance choice, food, grooming, training, boarding, walking, equipment, registration or licensing requirements if relevant, and likely vet costs, but do not give veterinary advice. Show the arithmetic in a table and list the source or description for every input. End with five questions that would most improve the estimate.
   
   Dog details:
   - Age: [age]
   - Breed or expected adult size: [breed or size]
   - UK location: [town or postcode area]
   - Health or special requirements: [details or none]
   - Exercise and care routine: [details]
   - Time left alone: [details]
   
   Prices and quotes I have gathered:
   [paste prices, links, quotes and notes here]
   
   My household budget or maximum affordable monthly amount:
   [amount or not provided]

   Open it prefilled in ChatGPT or Claude, or copy it into Gemini, which takes no prefill link.

3. Hand it to a person

   The distant third

   A person who owns the outcome does this end to end, worth it when the failure is dear.
