If your dog's nipples are getting bigger and it is a female it probably is having puppies soon. So watch over your dog and if they keep getting bigger, and bigger she would most likely be having puppies.
YESSS
they have crippled nipples:)
The nipples look darker and bigger as you may now be pregnant.
Nipples. Not Nibbles. Nipples. A dog has eight to ten nipples.
yes all dogs have nipples at least all my dogs have had them
Not necessarily. Dog nipples can enlarge due to other reasons like hormonal changes, pregnancy, or nursing from previous litters. Enlarged nipples may be a sign of labor approaching, but it doesn't definitively indicate the onset of labor.
Yes it can. All dogs have nipples, even the males.
Yes
you make them bigger\
Yes they do, all mammals have them, male and female. However, male dogs usually have immature nipples. Also, depending on the amount of fur, it is possible to not be able to find their nipples.
why would you want your nipples bigger anyways?
All dogs no matter the breed, or sex, have nipples.
