Most of the time, dogs with enlarged nipples are pregnancy. Along with enlarged and discolored nipples, the other indications that your dog is pregnant are decreased activity, change in appetite, unusual behavior, weight gain, and nesting behaviors.
Enlarged And Discolored Nipples
The development of enlarged or pregnant dog nipples is one of the signs of early pregnancy. A female dog’s nipples are usually small but when it becomes pregnant, her nipples will grow and become raised and noticeable.
After successful mating, you’d notice the enlargement of nipples to begin around 2 to 4 weeks and will continue to swell until it gives birth. Apart from growing bigger, her nipples will also turn darker as a result of increased blood flow.
Do you notice that your pooch is sleeping a lot? Lethargy and increased tiredness are the other signs of early pregnancy. So much is going on in her pregnant body so it’s normal if she does not show any interest in her usual activities such as playing fetch.
However, we do not recommend that you totally stop her exercise regimen, just take it slow so her body remains fit, healthy, and ready for the birth of her puppies.
Change In Appetite
The appetite of your pregnant pooch fluctuates depending on the stage of pregnancy. During the early part, you could see her eating less and may also vomit frequently, which is the canine equivalent of morning sickness.
Towards the middle stage of her pregnancy, her appetite increases, so you should gradually increase her food intake around the 5th week of pregnancy.
A lot of pregnant dogs become more clingy and affectionate, seeking more attention and increased cuddle time from their human families. On the flip side, some of them may display the opposite, preferring to be by themselves, being distant and withdrawn.
These are normal behaviors that are triggered by their fluctuating hormones.
As your pooch’s pregnancy progresses, you’d observe a significant increase in its weight along with her larger abdomen. If you touch her tummy, you may also feel some movements from her growing puppies.
Your pregnant pooch will let you know if she is about to go into labor through nesting behaviors. She’d begin to shred newspapers and gather materials like blankets and pillows to build a nest for her puppies.
At this time, your pooch may become more irritable and restless as it is preparing itself to give birth and to nurse her puppies.
At about 3 to 4 weeks after birth, the puppies’ weaning process should begin. And, one week after weaning, the enlarged nipples should slowly go back to their normal size because milk production is gradually decreasing. For some dogs, the sizes of their nipples may shrink but they will not likely return to the same size as before.
