As a proud owner of a small Cavalier King Charles Spaniel, you're likely eager to provide the best possible care for your furry friend. These adorable dogs require regular grooming to prevent matting and tangling of their beautiful coats.
Their coats should be brushed daily to prevent matting and tangling, especially around their ears and behind their legs. A weekly bath is also necessary to keep them clean and smelling fresh.
Cavalier King Charles Spaniels are prone to obesity, so monitoring their food intake and ensuring they get regular exercise is crucial. A 20-minute walk per day is a great starting point.
Their small size means they can be prone to dental issues, so regular dental care is essential. Brushing their teeth daily and providing dental chews can help keep their teeth clean and healthy.

Puppy Growth Stages
King Charles the Cavalier Spaniels, like all dogs, go through a variety of developmental stages during their first year.
Understanding these stages is critical for determining your puppy's size.
Height and weight discrepancies are common during puppyhood, but most of these aberrations seem to resolve on their own as your furry companion evolves into adulthood.
In the first few weeks of life, your Cavalier King Charles Spaniel puppy will grow rapidly, with their weight increasing from 0.5-0.7 Ibs at birth to 1.5-2.5 Ibs by week four.
Here's a breakdown of your puppy's expected growth during the first year:
By the time your Cavalier King Charles Spaniel reaches adulthood, they will typically weigh between 13-18 Ibs and stand between 12-13 inches tall.
Breed Characteristics
The English Toy and Cavalier King Charles Spaniel breeds have distinct physical characteristics. The Cavalier's desirable adult weight is 13 to 18 pounds.
Cavalier King Charles Spaniels are generally well-suited for living with other pets and dogs, as long as they're well socialized from an early age. This breed is known for being tolerant and should get along with cats, although it's worth noting that whether your cat likes your Cavalier is another story.
Genetics
Genetics plays a crucial role in defining your Cavalier King Charles Spaniel's size and build.
The IGF1 gene has a significant influence on size variances between breeds and size variations within the same breed.
Genetics is like a puzzle, and sometimes the parts just fall in the right place, resulting in a small Cavy due to genetic inheritance from their parents.
Size, Proportion & Substance
The English Toy and Cavalier breeds are both compact, with the English Toy being square in shape and sturdy of frame, while the Cavalier has a moderate bone structure in proportion to its size.
The English Toy has a desirable adult weight of 8 to 14 pounds, making it a great companion for those who live in smaller spaces.
The Cavalier, on the other hand, has a slightly larger adult weight of 13 to 18 pounds, and stands 12 to 13 inches tall at the withers.
This compact size makes both breeds perfect for city living or for families with smaller children.

Head and Mouth

The English Toy's head is quite large compared to its body, giving it a plush and chubby look. Its skull is high and well-domed, full over the eyes.
The Cavalier's head, on the other hand, is proportional to its body size. The skull is almost flat between the ears.
The English Toy has a deep, well-defined stop, and its muzzle is very short with the nose well laid back. A slightly undershot bite is actually a desirable trait in this breed.
The Cavalier has a moderate stop and a muzzle that's about 1 1/2 inches long from the base of the stop to the tip of the nose. A perfect, regular scissors bite is what you should look for in this breed.
The English Toy's jaw is square, broad, and deep, with a well-turned-up shape. A wry mouth is a fault in this breed.
The Cavalier's jaw is also well-shaped, but it's not as deep as the English Toy's.

Neck, Topline, Body, Tail

The Cavalier neck is fairly long, without throatiness, and muscled enough to form a slight arch at the crest. The body is short-coupled with ribs well sprung but not barreled.
The chest is moderately deep, extending to elbows. Slightly less body at the flank than at the last rib.
The Cavalier tail is well set on, carried happily but never much above the level of the back and in constant characteristic motion when the dog is in action.
Spaniels
Cavalier King Charles Spaniels typically weigh between 12 and 18 pounds on average, with males being slightly heavier due to their muscular physique.
They usually stand between 12 to 13 inches tall, with males often being a touch taller than females.
These friendly dogs are well-suited for families with other pets, especially if socialized from a young age. They tend to get along with other dogs just fine, and even cats can be tolerable companions.
However, it's essential to supervise interactions between your Cavalier and other small pets, as they can have a prey drive.
Their friendly nature makes them more inclined to say hello to people passing by, rather than other dogs.
Coat and Grooming
Cavalier King Charles Spaniels have beautiful, medium-length coats that are silky to the touch and may be slightly wavy.
Their coats come in four colors: Blenheim, Tricolor, Black and Tan, and Ruby. Blenheim is the most common color, with a rich chestnut on a pearly white background. Some Blenheims have a thumb-shaped chestnut dot on top of the forehead, called a lozenge.
The feathered hair on their ears, chest, legs, feet, and tail requires regular grooming. You'll need to comb or brush them three or four times a week, and bathe them as necessary, which might be weekly if they enjoy playing outdoors and spending time on furniture.
Their feathered hair is prone to tangling, especially on the ears and legs, so check those areas frequently for mats that need to be gently combed out. Trim the hair between the pads on the feet and clean their ears regularly to prevent infections.

- Blenheim: rich chestnut on a pearly white background
- Tricolor: black markings on a white coat with tan markings

Cavaliers are average shedders, but they don't need special trimming or clipping. In fact, it's preferred to let their feathering remain natural, although some people trim the feet for neatness' sake.
Health and Care
Cavaliers are generally healthy, but they can be prone to certain health conditions. Mitral Valve Disease (MVD) is a common condition in Cavaliers, which can start with a heart murmur that worsens over time and can lead to heart failure.
A small yard is adequate for their exercise needs, and they require daily walks or romps in the yard. They have no street smarts and will run right in front of a car if they catch sight of a bird or other interesting prey.
Some common health issues in Cavaliers include Mitral Valve Disease, Syringomyelia (SM), Episodic Falling, Hip Dysplasia, Patellar Luxation, and Keratoconjunctivitis Sicca (Dry Eye). Here are some key facts about these conditions:
- Mitral Valve Disease: can start as early as one or two years old, and research is ongoing to prevent it
- Syringomyelia (SM): symptoms typically appear between 6 months and 4 years old, and can include sensitivity around the head, neck, or shoulders
- Episodic Falling: symptoms can range from mild to severe, and can start before 5 months of age
- Hip Dysplasia: can be caused by genetics, environment, and diet, and may require surgery in rare cases
- Patellar Luxation: can be crippling, but many dogs lead relatively normal lives with this condition
- Keratoconjunctivitis Sicca (Dry Eye): can be treated with eye drops, but if left untreated, it can result in blindness

Teacup Spaniels
The Teacup Cavalier King Charles spaniel is a purebred dog, but it's not eligible to be registered with kennel clubs unless it's created by crossing Cavaliers with smaller spaniel breeds.
They typically have the same gentle and calm temperament as full-size Cavaliers, making them playful and independent little dogs.
Teacup Cavalier King Charles spaniels are ideally suited to living in small spaces, but they don't like being left alone and may develop separation anxiety and destructive behavior.
Finding a healthy dog and a responsible breeder can be difficult, so you must be extra vigilant about keeping them safe due to their size.
Formal Teacup Recognition
The Teacup Cavalier King Charles spaniel is a purebred dog, but it's typically not eligible to be registered with kennel clubs unless it's created by crossing Cavaliers with smaller spaniel breeds.

A group splintered from the original Cavalier club in the early 1990s and voted to be recognized by the AKC, but the original club still operates and has maintained its stance against formal recognition.
If the original Cavalier club's wishes had been granted, the Teacup Cavalier King Charles spaniel probably wouldn’t exist, as they wanted to avoid commercial breeding to protect the dogs' health.

Cavaliers make great family pets, especially if you have a household where someone is always around to spend time with them.
They're adaptable and can get along well with people of all ages, but it's crucial to supervise interactions with children to ensure everyone's safety.
Cavaliers need a safe space to relax and take a break from the action, so make sure you can provide a quiet spot for them to retreat to when needed.
Teacup's Rise to Popularity
The teacup dog fad, which included the Cavalier King Charles spaniel, gained popularity in the early 2000s.
Pop culture visibility sparked a real-world demand for tiny pups, following the success of a reality show featuring a teacup Chihuahua as Paris Hilton's pet.
Many breeds, including the Cavalier King Charles spaniel, received the teacup treatment during this time.
A rush of breeders with questionable ethics emerged, looking to cash in on the fad and produce these extra-small dogs.
Children and Pets
If you have kids and are thinking of getting a pet, it's essential to consider their safety and well-being. Cavaliers can be great playmates for kids who will enjoy throwing a ball for them, teaching them tricks, or simply having them on a lap while they read or watch television.
Supervise any interactions between dogs and young children to prevent any biting or ear or tail pulling on the part of either party. Teach your child never to approach any dog while they’re eating or sleeping, or to try to take the dog’s food away.
Cavaliers get along well with other dogs and can learn to play nice with cats and other pets if introduced to them at an early age. However, some Cavaliers may have a strong hunting instinct, so it's crucial to supervise their interactions with birds and other small animals.
It's also vital to make sure your dog has a safe space to relax when they want time away from children or other pets. As long as your Cavalier is well socialised from a young age, they'll enjoy the company of people of all ages, but they may not be the best fit for households with irregular schedules.
