no.
If the dog is an intact female, who was recently "in heat" and had the opportunity to mate, she may be pregnant. If she hasn't been in heat recently, or didn't have the opportunity to mate, she may be going through a false pregnancy. If the dog is a spayed female, or a male, the enlarged nipples can be a sign of disease, so a trip to the Vet is in order.
There are several reasons a female dog's nipples can become enlarged:in heat / pregnancyfalse pregnancysurrogate/induced lactationlow to the ground / physical irritationtumors / cancerSeek the assistance of a veterinarian to make sure.
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.
Pregnant?
I actually was wondering the same thing. I have a dog who is 11 months old and in her first heat. I called the vet because I was worried she may be pregnant when I noticed her nipples were swollen. I called my vet and they said it is normal during heat.
her belly grows bigger and her nipples pop out
She is pregnant and not far from giving birth
It could be a fake pregnancy if you female dogsmammary glands is enlarged then she is pregnant if not it is a fake pregnancy.This should help youhttp:/www.wisegeek.com/what-are-the-symptoms-of-a-pregnant-dog.htm
yes it is one of a few signs, some signs are nipples grow larger, dog becomes lazy, follows you around, keeps licking it rear end, behaviour change.Also, if you have received your dog from somewhere else at an older age, this may just mean that she has already had puppies before.
No, If you are talking about a female dog which I assume your are, the dog's nipples should become more normal after it is able to go in heat and if that does not happen it, it will happen when the dog is pregnant It is the exact same way with humans.
yes are her nipples leaking
Increased appetite, enlarged nipples, after 30 days she will start to get fatter, and a lilttle less activity after about 30 days.
