Estrus. When your female dog reaches this stage, she is ready and receptive to mating. The estrus phase usually lasts five to ten days.

Bloody discharge, licking of the genital area, increased food intake, and clingy behavior is typical signs of the proestrus stage.

Progesterone also intensifies the effects of estrogens in a female dog’s brain, causing outward signs of heat such as flagging of the tail and frequent urination as a sign of marking.

Diestrus. The ‘in heat’ stage is followed by the diestrus stage, in which your dog’s body will begin producing eggs after successfully mating.

She will rest for an average of two months if she doesn’t. It is at this time that the vulva returns to its normal size and the swollen nipples start shrinking.

My dog’s nips are swollen, but she isn’t pregnant.

An unspayed female dog may have swollen nipples due to phantom pregnancy, even if she is not pregnant. Fifty to seventy percent of female dogs will experience false pregnancy during their lifetime.

Let’s first discuss why false pregnancies happen before discussing the symptoms.

The main cause of false pregnancies is hormonal changes in the body as a result of the heat season, even if fertilization didn’t happen or was unsuccessful.

Puppies need their mothers to nurse them as they grow. Dogs are naturally inclined to do this. When several dog aunts in the pack undergo false pregnancies and produce milk, more pups will be nursed and have a higher chance of survival this way.

It usually takes a week or a month for false pregnancy symptoms to manifest. Your dog may be experiencing a phantom pregnancy if he exhibits physical or behavioral symptoms. The physical signs. Within 4 to 8 weeks after the heating season, false pregnancies are commonly detected.

The most common sign is swollen nipples or enlargement of the mammary glands. The swollen nipple glands also produce a serum that is lighter and less viscous than breast milk.

When your pooch is going through it, she’ll act as if she has puppies. Her favorite nook was filled with soft objects like stuffed toys, socks, and blankets. Beware because she will guard, nurture, and protect these things with her whole heart.

At this point, she believes that these things are her puppies, so please do not disturb her. If she perceives a threat, she may become aggressive.

What should I do about my dog’s swollen nipples?

The swelling in your female dog’s nipples should not cause any discomfort or pain. Monitoring what they are doing and making sure they are eating well is the best thing you can do.

If there are no open wounds associated with this swelling, it should go away without any medical treatment within a few weeks. You should consult a veterinarian if the swelling becomes worse or does not subside within this time frame.

Your dog’s swollen nipples should be evaluated by a veterinarian if they are accompanied by other symptoms, such as fever and loss of appetite.

A bacterial infection can also cause swollen nipples in your female dog. Infections are treated with antibiotics and other medications. The swollen nipples may become worse over time if improper treatment is not provided.

If the infection becomes abscessed, it will need to be drained so that it doesn’t become septic. Depending on the cause of the swollen nipples in your female dog, your vet will be able to identify whether it is an infection or if it is due to one of the other causes listed above.

How Can You Deal With False Pregnancy?

The causes of false pregnancies in dogs

During estrus, the ovaries also release eggs. Sperm from a male dog can fertilize these eggs. After the egg is released from the follicle, the corpus luteum remains.

If a woman does not become pregnant, she gradually loses this hormone. It produces progesterone, among other hormones, while it is present (about sixty days).

This will prepare her body to support an embryo and the pregnancy. Sometimes, however, the corpus luteum can stay there longer than usual, leading to confusion with pregnancy.

Pseudopregnancy is thought to be caused by the rapid drop in progesterone and the rise in prolactin.

Are dogs’ nips susceptible to infection?

It’s possible for your dog’s nipples to become infected.

Breast cancer and mastitis are two of these health issues. Another condition that can develop after a hot season is pyometra.

Mastitis. An infection that affects your female dog’s breasts is called mastitis. There is a good chance that a lactating female dog’s nipples are swollen if she has mastitis. Furthermore, swollen mammary glands are accompanied by discolored nipples that resemble bruises. 

You should not ignore the possibility of mastitis if you see pus or blood oozing out of her teats. Mastitis is a very painful condition, so don’t try to rub your belly or touch the mammary glands (unless you apply a warm compress). 

A mammary gland becomes inflamed when it is either infected by bacteria or accumulated with milk. Through the teats, bacteria enter the glands and cause infection. In some cases, however, mastitis is not caused by bacteria, but by excessive milk accumulating in the mammary glands.

The condition is treated with antibiotics and anti-inflammatory medications. It may help to massage her mammary glands gently to express excess milk if excessive milk is the cause. Keeping the dog’s nipples clean is also recommended with warm compresses applied four to six times a day.

Mammary Cancer. Swollen nipples can also be caused by a mammary gland tumor, which is a growth of a mass near the nipples. Breast cancer can be compared to this condition.

It is common for intact and unspayed dogs to develop mammary gland problems like cancer because the hormones during the heat cycle can cause abnormal growth.

Eventually, the tumor develops into an abscess, whether it is soft or hard. Tumors are not all cancerous; benign ones grow more slowly and have a smoother texture. The growth of a malignant tumor is rapid and has an irregular shape.

Pyometra. There is a serious medical condition that threatens the life of your female dog. It occurs 4 to 6 weeks after the end of the heat season, more often in women who have not given birth. An infection in the uterus can cause pyometra.

The cervix of a woman with an open pyometra will be relaxed and she will have a foul-smelling vaginal discharge. A closed pyometra causes abdominal swelling because the pus inside the uterus is trapped.

Left untreated, the uterus will rupture, causing a high fever, rapid heart rate, and sepsis in the female dog, which may lead to death in severe cases.

What Is Mastitis?

Mastitis is a common concern among female dog owners, especially if they have small children. The mammary glands of dogs are infected with mastitis.

It typically affects female dogs who are nursing a litter of puppies for the first time. During nursing, pups may scratch their mother’s nipples as a result of their young age, which can cause them to crack. A bacterial infection can then begin in the milk ducts. It can also affect male dogs. 

This condition causes the following symptoms: Itching around the nipple area, Nipple pain, Pus or thick, stringy milk coming from the nipples, Redness in and around the mammary glands, Fever; chills; fatigue; loss of appetite; vomiting, Crying, Lethargy, Enlarged lymph nodes near the mammary glands. 

Dogs of some breeds are more likely to develop mastitis than those of other breeds. Due to their size, beagles and German shepherds have a tendency to suffer from this condition. To prevent mastitis, small-breed dogs should not be bred before they are two years old.

The entire litter should be monitored if a dog has mastitis in order to prevent it from spreading. By licking one another’s mammary glands, dogs may transmit this disease to one another. If a mother has mastitis, puppies should not drink her milk – it is toxic to them.
