I have a 6 month old dachshund. I would like to know at what age will she come into heat? I have been told different times. I do not want her to have puppies. I am planning to have her spayed as soon as possible. Thank you for your help

At 6 months of age she's more then old enough to be spayed. Most vets say it's better to spay before the first heat, so now is the time to do it.

Yup any time now. Like Alty said, best before first heat! Congrats on getting her spayed. You are a very responsible pet owner!

6 month is a good age to be spayed as others have suggested.
There is debate as to whether it is better to spay before or after their first heat, same with neutering.
Personally I don't think it matters... if you do it before, you avoid that horrible 3 weeks of bleeding, moodiness and whining to get to males.

Smaller dogs come in heat anywhere from 6 months to 12 months, it really depends on the individual dog.
