In recent times, this teacup canine has gained popularity among dog lovers fond of smaller variations of popular breeds.

With his affectionate demeanor, this pooch is great for apartment dwellers as a Lapdog.

This dog may be small but his personality is not. However, as much as this dog is endearing, he may not be suitable for all individuals or families.

Why is that the case? read on to learn more.


Teacup Cavalier King Charles Spaniel information

You may not know this but King Charles Spaniel almost went extinct during the second world war. But thanks to 6 six dogs from this breed that survived the war, we have a miniature version and mixes from this dog.

The miniature version is also known as the “Mini/Teacup Cavalier King“, or “Teacup Cav“. They are super cute canine friends with wide eyes and flowing coats.

However, this cute appearance comes at a high price making the Teacup Cavalier King Spaniel expensive.

So, how did the Mini Cav come to be?

There are several methods that breeders use to create this dog that include 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 hence 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 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 as they are not able to compete for their 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’s mostly health-related. Thus, they are prone to developing health complications such as heart diseases and immunity issues.

Therefore, it’s essential that you avoid a Mini King Charles Cavalier bred from a runt.

2. Dwarfism

Dwarfism is a genetic mutation that randomly and naturally occurs or but can be deliberately introduced by the breeder.

The deliberate introduction of the dwarfism gene to create Mini Cavalier King Charles Spaniels is also highly discouraged and unethical. It occurs when a breeder mates two dogs with the dwarfism gene.

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

This method of breeding teacup 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 purchased a Miniature Cavalier bred using this method, carry out a DNA Dwarfism gene test.

3. Crossing King Charles Cavalier with smaller dog breeds

This is arguably 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
