A dog’s monthly cost depends on their size, health, diet and how much paid care your household needs. PDSA publishes minimum estimates of £69 for a small dog, £83 for a medium dog and £116 for a large dog, calculated using 2024 prices. Treat those as dated starting points, not current all-inclusive quotations.

Understand what the minimum leaves out
PDSA’s calculation covers a basic set of recurring needs, including food, insurance and routine-care items. It excludes several potentially substantial costs, such as paid boarding, grooming, training and veterinary treatment for illness or injury. Your own budget needs to address the services and risks relevant to your dog.
A dog who needs a walker on several working days can cost considerably more than one whose household covers every outing. Coat care, specialist feeding and changing insurance premiums can also alter the total without the dog’s basic size changing.
Build the budget from actual quantities
| Category | How to calculate your monthly figure |
|---|---|
| Food | Use the actual daily portion and the normal pack or subscription price. |
| Insurance | Obtain a quote for this dog and check cover, excesses and exclusions. |
| Routine veterinary care | Ask the practice for an individual schedule and current costs. |
| Grooming | Multiply the appointment cost by the expected annual visits, then divide by 12. |
| Walking or day care | Use the number of paid sessions you realistically need. |
| Holiday care | Budget annual nights and spread the cost across the year. |
| Consumables and replacements | Allow for poo bags, dental supplies and worn equipment. |
Do not compare foods only by bag weight. A daily feeding quantity connects the price to how long the food actually lasts. For subscriptions, use the ongoing price after introductory discounts and include regular extras.
Convert irregular bills into monthly planning
An illustrative £60 grooming appointment every eight weeks works out at about £32.50 a month when calculated as £60 × 52 ÷ 8 ÷ 12. That is an arithmetic example, not a quoted grooming price. Replace both figures with your groomer’s estimate and the schedule appropriate for your dog’s coat.
The same method works for holiday care. If you expect a certain number of nights away each year, multiply them by the provider’s actual nightly charge and divide by 12. Include any relevant collection fees or additional services rather than assuming the headline price covers everything.
Separate setup spending from ordinary running costs
Buying or adopting the dog, initial equipment and any early veterinary work belong in a separate starting budget. They should not disappear from your planning simply because they are not repeated monthly.
Some equipment will also need replacing as a puppy grows or an item wears. List the essentials you already own, their condition and likely fit. Buying everything in advance can be wasteful if you do not yet know the dog’s measurements or preferences.
Plan for health costs realistically
Insurance terms vary. Read the policy’s limits, exclusions and excesses, and check how ongoing conditions are handled. A monthly premium does not mean every future bill will be paid in full. Keep room in your financial planning for costs you may need to meet yourself.
Ask your vet about the dog’s routine needs rather than copying a generic treatment shopping list. Preventive-care arrangements should be appropriate to the individual, and a health plan is not automatically the same thing as insurance.
Cut waste before cutting useful care
Compare like-for-like consumables and avoid buying more food than you can store and use appropriately. Find dog poo bags on Amazon UK. For poo bags, the number you can actually use, ease of opening and reliable handling matter more than a large roll count on its own.
Review optional subscriptions and duplicate toys. If paid walking is a major expense, our dog walking cost guide helps identify what to ask a provider, but obtain a current local quote before committing.
Revisit the figure when life changes
Update the budget at insurance renewal, after a change in feeding or health needs, and when work or travel patterns change. A realistic monthly figure is a living household calculation. It should reflect how this dog will be cared for, not just the lowest number that makes adoption or purchase seem affordable.
