Hi, I have a almost 7 yr old mini Dachund, I'm trying to get her pregnant, I would like to know, if 7 yrs is an OK age for her, and that she won't have problems or anything...

Thank you

HI,
To the best of my knowledge, female dogs do not go through menopause, as pointed out by this site:

At 7 yrs old, your dog is probably OK to get pregnant. I would hesitate at much older dogs, say over 12 yrs old, due to infections, other disadvantages.
I would also check with your Vet, and get his/her opinion. Best of luck.
