The Real Cost of Dog Ownership in the UK
Before you bring a dog home, it helps to know the minimum you'll spend, where the big bills hide and which costs the law won't let you skip.
A dog costs at least £6,200 to £18,800 over its life, depending mainly on size, according to the People’s Dispensary for Sick Animals (PDSA), a vet charity. That’s the floor to plan against, and the lower end assumes a small dog with no serious illness along the way, the real number for most owners sits somewhere higher.
What it costs to get a dog
Rehoming from Dogs Trust costs £300 in England, Wales and Scotland, and £287.50 in Northern Ireland. That fee covers a health check, vaccinations, worming, neutering (or a voucher) and microchipping, and the dog goes home with four weeks of free pet insurance.
Whichever route you take, the legal side of ownership starts on day one. Our guide to your legal responsibilities as a dog owner covers what the law expects beyond the bill.
Monthly costs by size of dog
PDSA’s minimum monthly figures, calculated with 2024 prices, are £69 for a small dog, £83 for a medium dog and £116 for a large one. There is no single average monthly cost for a UK dog.
On top of that, PDSA puts the initial setup at £415 for a small dog, £531 for a medium and £560 for a large. That covers the things you buy before the dog comes home. If your monthly budget can’t hold the minimum for your dog’s size with room to spare, it’s worth knowing now.
Vet bills and insurance
PDSA’s figures cover routine care; illness and injury vet bills sit outside them. The Association of British Insurers (ABI) says the average claim was £685 in 2024, up 3% on the year before. A record £1.23 billion was paid out in claims that year.
In 2025, 51% of owners told PDSA they were worried about affording veterinary care. Keep a savings buffer, and read what any policy covers before buying.
What the minimum includes
The lifetime figure covers the everyday basics: initial vaccinations, worming and flea treatment, neutering, boosters, insurance, food, toys, poo bags and toothpaste. It doesn’t include the price of buying the dog, vet fees for illness or injury, or special diets. It also leaves out boarding, grooming, training and day care. In PDSA’s 2023 Animal Wellbeing Report, 45% of dog owners underestimated the minimum monthly cost of owning their pet.
Microchipping and registration
Microchipping is a legal requirement for dogs across the UK, and it’s one of the cheaper items on the list. In England, Wales and Scotland, every dog older than 8 weeks must be microchipped. The dog must also wear a collar and tag showing the owner’s name and address when out in public. In Northern Ireland, you need a dog licence before taking a dog home, and the council won’t issue one unless the dog is microchipped. The licence costs £12.50, with concessions.
Microchipping usually costs between £10 and £30. Our dog microchipping page explains how it works and how to book.
The chip holds only a number. Your name, phone number and address sit on a database under that number, and keeping those details right is up to you. Registering a pet with Pet Database is a one-off £20, with no subscription, and updates are free. If you’re taking on a dog that’s already chipped, from a friend, a breeder or a rescue, the record needs to move into your name. Our guide to transferring microchip ownership walks you through it.
The next step is to register your dog’s microchip so your details are on record.
