Amenorrhea in female dogs?

Question

This question may sound very strange. My 1.5 yr. female doxie was due for her period in April, but she never started. There is no possible way that she's pregnant. Should I worry about this?

I realize that in women, those with low body weights are prone to this condition. She is very small, but within the normal weight range of a dachshund.

Answer 1

I have had two female dogs that rarely bled. Maybe its not that much for you to notice or she licks it clean

Answer 2

Many dogs are not every 6 month cyclers. Even if she has had 2 other cycles that were 6 months apart, she can go 7-9 months before the next one. I am sure it will happen.
