Congenital Tail Defects
Congenital tail defects, including natural bobtail, are caused by a specific genetic mutation and may be associated with vertebral anomalies.
Detailed Description
The natural bobtail trait is caused by a mutation in the T-box gene. While most affected dogs are healthy, homozygous mutations can be lethal or associated with spinal defects. Responsible breeding is necessary to avoid health issues.
Common Symptoms
- Short or absent tail
- Rarely, hind limb weakness
- Rarely, incontinence if spinal defects present
Management Options
- No treatment needed for isolated bobtail
- Supportive care for spinal defects
Frequently Asked Questions
Is the natural bobtail harmful?
Usually not, but spinal defects can occur if two bobtails are bred together.
Can I test for the bobtail gene?
Yes, a DNA test is available.
Should two bobtail dogs be bred together?
No, due to risk of lethal or severe defects.
Is tail docking necessary?
No, the breed standard allows natural bobtails.
Are bobtail dogs less healthy?
Not if bred responsibly.
