When a female Chihuahua is in heat, her body undergoes hormonal changes that can lead to the swelling of her nipples. This swelling is a natural response to the increase in estrogen and progesterone, preparing her body for a possible pregnancy. Additionally, the nipples may become more prominent as part of the overall reproductive cycle. If you have concerns about your dog's health, it's always best to consult a veterinarian.
Pregnant?
A dog's nipples may swell during of after her heat cycle. They can stay swollen for up to two weeks after her heat is finished. If they stay swollen longer than that, it's time to have her checked out by a vet.
She may be pregnaant, if not, in heat.
If her nipples are getting bigger then chances are she's on heat.
If your pet Chihuahuas neck glands are swollen, you should take him to the vet. A vet will be able to treat your pet the best they can.
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.
It could be puberty.
well i am not sure but i think it is normal because my dog had pupps and she was fine my friend's dogs nipples were swollen !
Have you taken a pregnancy test?
Take your animal to the vet to be 100% sure what the problem is, the sooner you do this the better.
only if they are pregnant.
Twice a year.
