5 Fascinating Comparisons of UK’s Top Dog Breeds

There are over 240 different dog breeds worldwide, but some are undeniably more popular across the UK. Breed popularity shifts slowly over years, yet recent trends show fascinating changes—especially the rise of the French Bulldog, which has smashed records in recent years.

UK dog lovers can likely guess the top breeds, as they’re a common sight everywhere. Using data from Pets4Homes, the UK’s largest dedicated pet classifieds website, alongside Kennel Club registrations, here are five fascinating comparisons of the five most popular dog breeds in the UK, updated for 2025.

The five most popular dog breeds in the UK, ranked

Based on Pets4Homes adverts and Kennel Club puppy registrations, the UK’s top dog breeds differ slightly, reflecting variations between demand for pedigree puppies and general UK pet interests.

1. The French Bulldog

The French Bulldog is officially the UK’s most popular dog breed, topping Kennel Club registrations and Pets4Homes adverts alike. Known for their charming “bat ears” and affectionate nature, they’re extremely popular among urban dog owners. However, their brachycephalic (short-nosed) anatomy requires careful health monitoring to avoid respiratory issues.

2. The Chihuahua

Pets4Homes data places the Chihuahua second in popularity, though the Kennel Club ranks the Labrador Retriever as second for pedigree registrations. The Chihuahua is a tiny, lively companion dog, perfect for small homes but prone to fragile bones and dental needs. Meanwhile, the Labrador remains Britain’s beloved large family dog.

3. The Pug

Pugs hold third place for Pets4Homes popularity, admired for their playful and loving temperament. The Kennel Club ranks the Cocker Spaniel third, celebrated for its friendly and energetic character. Both breeds are small but have notable health considerations, including respiratory risks for the Pug and a predisposition to ear infections and hip problems for Cocker Spaniels.

4. The Cockapoo

The Cockapoo, a highly popular hybrid not recognised by the Kennel Club as a formal breed, ranks fourth on Pets4Homes. They combine the intelligence and hypoallergenic traits of Cocker Spaniels and Poodles, with generally good health thanks to hybrid vigour, making them a sought-after family and companion dog.

5. The Cocker Spaniel

Rounding out the top five, Cocker Spaniels combine charming energy and friendliness. The Kennel Club’s fifth spot goes to the English Springer Spaniel, a breed more associated with active outdoor lifestyles. Cocker Spaniel owners should watch for breed-specific health issues such as ear infections and hip dysplasia.

Answers to common questions

Where to buy a puppy or dog?

Quick Answer: Choose reputable breeders and consider rescue organisations to ensure ethical buying.

Finding a puppy safely and responsibly involves researching breeders who conduct health testing, provide proper socialisation, and avoid puppy farming. The Kennel Club's Find a Puppy service and Pets4Homes offer trusted sources. Rescue organisations also offer lovely dogs needing new homes.

How much does it cost to buy a popular breed?

Quick Answer: Costs vary widely but French Bulldogs are generally the most expensive breed among the top five.

Expect to pay around £1,300–£1,400 for a pedigree French Bulldog, with other breeds typically costing less. Prices depend on breeder reputation, location and whether the dog is pedigree registered.

Which breeds are best for families?

Quick Answer: Cockapoos and Cocker Spaniels are excellent family choices due to their friendly nature and trainability.

While all breeds have unique traits, the Cockapoo is highly intelligent and adaptable, often suiting families with children and those seeking hypoallergenic dogs. Cocker Spaniels are cheerful and loyal family pets. French Bulldogs and Pugs enjoy companionship but may need more careful management due to health concerns.
