Is a Boston Terrier with Blue Eyes Okay?
The Merle Gene
Blue eyes in Boston Terriers are caused by the merle gene, which is a dominant gene that affects coat color and eye color. The merle gene can cause a variety of coat colors, including blue, red, and black. It can also cause blue eyes, brown eyes, or a combination of the two.
The merle gene is not unique to Boston Terriers. It is also found in other breeds, such as Australian Shepherds, Border Collies, and Dachshunds.
Health Concerns
There are some health concerns associated with the merle gene in Boston Terriers.
- Deafness: The merle gene can cause deafness in Boston Terriers. This is because the merle gene can affect the development of the inner ear.
- Eye problems: The merle gene can also cause eye problems in Boston Terriers. These problems can include cataracts, glaucoma, and other eye conditions.
- Skin problems: The merle gene can also cause skin problems in Boston Terriers. These problems can include allergies, dermatitis, and other skin conditions.
Genetics
The merle gene is a dominant gene, which means that it only takes one copy of the gene to cause the merle phenotype. This means that if a Boston Terrier has one copy of the merle gene, it will have blue eyes and a merle coat. If a Boston Terrier has two copies of the merle gene, it will have blue eyes and a double merle coat.
Double merle Boston Terriers are often more likely to have health problems than single merle Boston Terriers. This is because the double merle gene can cause more severe health problems.
Conclusion
Boston Terriers with blue eyes are beautiful dogs, but it is important to be aware of the health concerns associated with the merle gene. If you are considering getting a Boston Terrier with blue eyes, be sure to do your research and talk to your veterinarian about the potential health risks.
