About the Teacup Cavalier King Charles Spaniel

Most people may not this but the King Charles Spaniel breed almost went extinct during the Second World War.

But thanks to 6 six dogs from this breed that survived the war, we have been able to see the miniature versions and mixes of this dog.

This miniature version is also known as the “Mini/Teacup Cavalier King“, “Teacup Cav“, or “Teacup Cavies.”

These dogs are some of the cutest canine friends you are ever going to own or come across with their wide eyes and flowing coats.

However, this cute appearance comes at a high price which makes the Teacup Cavalier King Spaniel as expensive as its predecessor the Teacup French Bulldog.

So, how did the Mini Cav come to be?

There are several methods that breeders use to create this dog including the following;

  • Mating King Charles Cavalier with smaller breeds.
  • Breeding of runts.
  • Dwarfism.

Let us look at each of these breeding methods in more detail.

1. Repeated breeding of Runts

This breeding practice is considered unethical and it is.

I would not recommend getting a Teacup King Charles Cavalier bred through this method as the pup may develop serious health complications later on.

Let me explain. 

When Cavalier Spaniel puppies are born, some are born underweight and smaller than the rest. These puppies develop to become smaller over time and are known as runts.

So, runts are simply the smallest dogs in a litter.

These puppies don’t grow as big as they are supposed to mainly because they are not able to compete for the mother’s milk as well as the other puppies and other reasons.

There is also a reason why these puppies are born underweight in the first place and it is almost always health-related.

Runt pups are therefore prone to developing serious health complications such as heart diseases and immunity problems.

You should, therefore, avoid Mini King Charles Cavaliers that have been repeatedly bred from runt to make them even smaller with time.

2. Dwarfism

This is a genetic mutation that can occur randomly and naturally or with the deliberate introduction of the dwarfism gene by the breeder.

The deliberate introduction of the dwarfism gene to create Mini Cavalier King Charles Spaniels is also highly discouraged and unethical.

This occurs when a breeder mates two dogs that have this dwarfism gene.

When this is done the offspring’s growth is restricted which gives him an abnormally small body and short feet.

This method of breeding teacups can also cause health problems in the dog such as;

  • Hair loss
  • Heart complications
  • Underdeveloped muscles.
  • Spinal problems.
  • Dental problems.

If you suspect that you are about to purchase a Miniature Cavalier bred using this method carry out a DNA test for the dwarfism gene.

3. Crossing King Charles Cavalier with smaller dog breeds

This is the best method of breeding Teacup Cavs as it reduces the risk of health complications.

However, when this is done there is also the chance the resulting offspring may be more like the other breed and less like the Cavalier King Charles Spaniel.

The offspring has to have more Cavalier Spaniel traits and looks and should weigh under 10 pounds to be considered a Miniature Cavalier King.

Breeds that are commonly used are;

  • Teacup Poodle
  • Chihuahua
  • Mini American Eskimo dog
  • Maltese
