You asked: What causes dog metritis?

Metritis is inflammation of the endometrium (lining) of the uterus due to a bacterial infection, usually occurring within a week after a dog has given birth. It can also develop after a natural or medical abortion, miscarriage, or after a non-sterile artificial insemination.

What are the first signs of pyometra?

Symptoms of pyometra include early warning signs of the animal feeling unwell, such as vomiting, refusal to eat, lethargy, increased thirst and frequent urination. She may also appear to be uncomfortable, because pyometra is a particularly painful condition for dogs, while being somewhat less so for cats.

What is the difference between metritis and pyometra?

DEVELOPMENT. Metritis is infection of the uterus. This is not the same as pyometra, which is infection overlying the uterine abnormality termed cystic endometrial hyperplasia (see Chapter 16). Metritis occurs when the normal flora of the reproductive tract are allowed to colonize the uterus postpartum.

What causes dog uterine rupture?

Rupture during the whelping is most likely to occur in cases in which the uterine wall is compromised by the presence of infection, a dead foetus, uterine torsion, or careless obstetrics procedures. It can be also caused by excessively large doses of oxytocin (Jackson, 2004a ).

What is the most common bacterial cause of canine pyometra?

Can pyometra go away on its own?

It’s caused by the womb filling with pus and, if left untreated, it can lead to kidney failure, toxaemia, dehydration and, in some cases, death. Usually the only cure once the pet has developed pyometra is emergency surgery to remove their womb.

What color is pyometra discharge?

In an open pyometra the pus discharges out of the vagina – as seen by a yellow, green or red/brown copious discharge from the vulva of the dog. The diagnosis of an open pyometra is therefore easier if there is a visible discharge. A closed pyometra is when the cervix is closed and there is no discharge.

How is metritis treated?

Antibiotics commonly used for the treatment of puerperal metritis include penicillin, third-generation cephalosporins, or a combination of ampicillin with oxytetracycline or cloxacillin (Nak et al., 2011).

Can antibiotics cure pyometra in dogs?

Antibiotics will improve the general status of the bitch but cannot resolve the uterine infection on their own. Given the increased vaginal discharge after prostaglandin administration, we recommend administering the drug early in the morning and hospitalizing the bitch for 4–6 h.
