4.Ethical Controversies In Genetics

Blue Merle Chihuahuas are not considered purebred since the Merle gene naturally occurs in larger dog breeds. Experts believe that Chihuahuas acquired this gene through crossbreeding.

Breeding two Blue Merle Chihuahuas together is strongly discouraged even if they are unrelated. There is a high probability of the resulting puppies being born with defects or health issues.

Some Chihuahuas can carry the Blue Merle gene without displaying the characteristic pattern. These Chihuahuas, known as phantom merles, appear like regular Chihuahuas despite having the blue merle gene.

Not all them are ethically bred. Some breeders attempt to produce puppies by breeding two Blue Merle Chihuahuas together, often leading to puppies with deafness or blindness.

They can come with a significant price tag due to their high demand. The average cost of a Blue Merle Chihuahua is around $1,500, although some can be priced as high as $10,000.

Providing a balanced diet that meets their nutritional requirements is crucial for the overall health and well-being of them, just like any other Chihuahua. Consulting with a veterinarian can help determine the specific dietary needs of your dog based on their age, weight, and any specific health considerations.

Life Expectancy and Common Health Issues

is Blue Merle Chihuahua healthy?

Blue Merle Chihuahuas are prone to several health problems, including:

  • Deafness: Deafness is more common in Blue Merle Chihuahuas than in any other breed. This is because the Merle gene affects the pigmentation inside the ears, leading to the accelerated degeneration of nerve endings and hearing loss.
  • Blindness: Blue Merle Chihuahuas have a higher likelihood of being born blind or developing blindness over time. The reduced pigmentation inside their eyes makes them sensitive to bright light. Protecting them from the sun is essential by providing shade on bright sunny days.
  • Skin cancer: The loss of pigmentation caused by the Blue Merle gene exposes certain areas of the Chihuahua’s body to increased UV ray exposure, which raises the risk of skin cancer.
  • Color Dilution Alopecia: Blue Merle Chihuahuas with lighter-colored hair are susceptible to Color Dilution Alopecia (CDA). This condition leads to the appearance of bald patches and can be accompanied by itchy or flaky skin, as well as other infections.
  • Microphthalmia: They may be born with malformed or uneven eyes, known as microphthalmia. This can result in partial or complete blindness.

It is essential to be aware of these health issues and provide appropriate care and attention to puppies to ensure their well-being.
