My dogs nipples are getting big she is 3 years old in may. I don't know if it is a sickness or if it is like a period for female dogs. Oh and if this means she is pregnant answer quick because I heard that when a dog is pregnant it only takes 2 months!

Hi Tessie15cool,

I see this was from several days ago. Did you find an answer yet?

If your dog hasn't been spayed, it could be due to her going into heat. Sometimes you may notice the nipples enlarge when she is close to ovulation.

Do you know if she has been around any male dogs? If so, then pregnancy is going to be a possibility. What sort of dog is she? Has she been gaining any weight?

If she has been spayed, then there can be some medical conditions that may cause it, but you would need to have her seen by a vet to determine the possibilities.

Gestation is normally 63 days and mammary glands swell after the 35 th day. So your dogs is not altered, right?
