    Dachshund

    Dachshunds come in two sizes; standard and miniature, with three main coat types to look out for. Their longer backs mean the require some extra care and attention around stairs and furniture. Watching their weight is important as their backs can be prone to injury if carrying additional weight.

    Jack Russell Terrier

    Smart, high-energy and keen to play at all times, Jack Russell are ideal for owners who keep active, enjoy long walks and playing games. One thing to keep in mind: they have a high prey drive, so be sure to do plenty of recall training and always keep at it.

    Miniature Schnauzer

    Most known for their beards and eyebrows, they're very intelligent and pick up new skills quickly. It is good to note that miniature schnauzers do need regular grooming despite not shedding very much.

  • Lap Dog

    Italian Greyhound

    A small, slender sighthound with a motivation for snuggling up with their owners under a warm blanket. Italian Greyhound's can grow very attached to their owners, and will always be very affectionate and playful, out with their quick sprint burst of energy they love to sleep and curl up somewhere warm.

  • Fun-Loving

    French Bulldog

    Frenchies have become one of the UK's most popular dog breeds in recent years, as they are playful, full of personality and lovingly affectionate. As they are a flat-faced breed, some can struggle with breathing and many with heat, so ensuring proper health checks will be key to giving them the best life you can.

  • Fluffy Friend

    Bichon Frise

    Bichon Frise have very soft, curly hair that sheds very little. They are cheerful love to cuddle and are great with people of all ages. To keep their famous fluff looking its best, regular grooming is recommend

  • Tiny but Mighty

    Yorkshire Terrier

    Yorkshire Terriers are confident, nosy and full of that classic terrier spirit. But don't let the size fool you! They can be vocal, so starting training early can be a great help.

Thinking about a crossbreed? Many mixed breeds are very popular dog breed choices in the UK, such as the Cockapoo or the Cavapoo. Their size, coat, temperament and personality can very greatly depending on their parents, so it's good to ask to meet both where you can.

How to Choose the Right Small Breed

Finding the perfect match for your lifestyle

  • Energy levels - Terrier breeds like the Jack Russell will need plenty of exercise and enrichment, where breeds such as Italian Greyhounds are happier with shorter strolls, and typically have only one burst of energy daily.
  • Grooming - Low-shedding breeds, Bichon Frise and Miniature Schnauzer will still need regular brushing and professional grooming within their routine.
  • Family life - Smaller dogs can definitely be more on the delicate side, so small or young children should always be supervised and taught to be around and play with them gently.
  • Time at home - Lots of smaller dog breeds are companion dogs, and don't cope well when left alone for longer periods. If you and your family work long hours outside of home they may not be the right fit for you.
  • Health - We always recommend researching the most common health problems in your favoured breed, and as you move through the process ask the breeder or rescue centre for health test results.

Have you considered rescue? There are lots of rehoming charities across the UK or rescue centres that can help match you with the right dog. There are plenty of amazing smaller dogs of all ages that deserve to come home with a loving family, to a happy and healthy home.

Health Issues in Small Dog Breeds

What to keep an eye on

  • Breathing Problems

    Prominent in flat-faced breeds like French Bulldogs, Pugs and Shih Tzus and made worse in hot weather or when exercising. Symptoms and signs can include noisy breathing, snoring and tiring quickly.

  • Back Problems

    Most common in long-backed breeds like our loving Dachshunds, they can be prone to disc problems in their spines. It is important to keep them a healthy weight and making use of ramps to help them navigate furniture to protect their backs.

  • Heart Conditions

    King Charles Spaniels are most notably prone to mitral valve disease, which is a heart condition that often develops as they get older. It is important to keep regular vet check-ups to help catch it early.

  • Dental Disease

    Smaller mouths can sometimes mean crowded teeth, this can cause plaque and tartar to build up more easily and more frequently. Regular brushing and dental check-ups are very important for smaller breeds. Dental chews can be a great addition to their daily routine to help reduce tartar formation through increased salivation and abrasion.

  • Kneecap Problems

    Italian Greyhounds we're looking at you! Slipped kneecaps can be common in many smaller or toy breeds, known as luxating patella, or even as severe as a broken leg. It is recommended to keep a close eye on them when jumping off or around furniture, keeping it to a low height where possible. If you notice your dog skipping, or holding their back leg up while they walk, it's best to see the vet.

If you notice anything unusual: If your dog has any trouble breathing, looks to be experiencing pain, is reluctant to move or starts limping, it is best to contact your vet. Getting a problem looked at early will make it much easier to manage and keep on top of.

Feeding a Small Dog

Little dogs, big appetites

It is common for many breeds of small dogs to use energy more quickly for their size than larger dogs, but with smaller tummies every mouthful counts! With their size, it can also be very easy to overfeed a small dog, even a few extra treats here and there can quickly lead to unwanted weight gain.

  • Portion control - Follow a feeding guide for dog's activity level and weight, be sure to consider their body condition or any additional allergies or conditions. Check out for Feeding Guide for more detailed information.
  • Quality ingredients - Choose a complete food, made with plenty of real, human grade meat and whole ingredients to ensure every bite is packed with nutrients. Our fresh menus can be a great place to start, explore over 10 flavours here today.
  • Count the treats - Treats should always be included in a dogs daily food intake and should make up no more than 10% of their daily allowance, so pick small, natural rewards.
  • Keep weight in check - Additional weight can put unwanted strain on small joints and backs, especially for breeds like Dachshunds, it is wise to add regular weigh-ins to your routine as you monitor this.
