Pyometra – Understanding the Danger and the Frequency

Last month we published an article To Spay or Neuter? Health Questions and New Procedures. In response to this article two readers offered comments regarding the danger of the development of pyometra in an intact bitch. So, to start I want to thank both, Mary A. McLoughlin DVM, MS, Diplomate ACVS and Dr. Susan Adams-Conley, DVM, President Bellingham Animal Hospital, P.C. for sharing their concerns. Their comments prompted me to do a bit more searching so I could share more information with you about pyometra, a fatal infection that every owner of an intact female should be very aware of and most importantly know how to respond if suspected.

To understand the frequency at which pyometra occurs I found a source of statistical material pulled from a Swedish pet insurance data base. I found this material especially telling as the majority of the dogs in Sweden are intact which meant there was a very large population of bitches included in the data. “Patty Olson, DVM, Ph.D.  “In Sweden, 93 percent of dogs are intact,” she says. “They don’t neuter.”

The data indicated that breed and age are a factor in the occurrence of pyometra with some breeds being more prone to the infection while others were less so. On the plus side for Gordon Setters owners, we were not among the top ten breeds most prone to pyometra, however our breed is still at risk like all other breeds, so don’t let that lull you into complacency. Using an overall crude average a bitch under 10 years old has approximately a 2% chance of developing the infection in any 12 month period of her life and the data further shows that by the age of ten somewhere between  23% – 24% of surviving bitches will have developed pyometra. Simple math – your intact bitch has about a 1 in 4 chance of developing pyometra by age 10.

For those of us who show and breed our Gordon Setters, this means that each and every year of their life we face a 2% chance of our bitch developing pyometra, or we could choose to spay her ending that risk along with her breeding potential and show career. There are no easy choices here for breeders or dog show enthusiasts. One thing is for certain though, if we own intact bitches we owe it to them to know the signs and symptoms of the infection and we need to be prepared to handle it as an emergency.

What is Pyometra?

  • Pyometra is an infection in the uterus.
  • .The cervix, gateway to the uterus, remains tightly closed except during estrus when it relaxes to allow sperm to enter the uterus which also means that bacteria that are normally found in the vagina may also enter the uterus.
  • Pyometra may occur in any intact young to middle-aged bitch but is most common in older females.
  • Pyometra usually occurs two to eight weeks after the last estrus.
  • Open pyometra means that the cervix remained open. Symptoms may include pus draining from the uterus out through the vagina. You may find pus or an abnormal discharge on the skin or hair under the tail, or possibly on bedding and furniture Fever, lethargy, anorexia, and depression may be present.
  • Closed pyometra means just that, the cervix is closed and so the pus that forms in the uterus cannot drain. It collects in the uterus ultimately causing the abdomen to distend. The bacteria release toxins that are absorbed into the bloodstream. Bitches with closed pyometra become severely ill very rapidly. They may refuse food, may be very listless and depressed and might also suffer from vomiting or diarrhea.
  • Toxins may affect the kidney’s ability to retain fluid causing increased urine production as well as increased water consumption in both open and closed-cervix pyometra.
  • The preferred treatment is to surgically remove the infected uterus and ovaries – spay.
  • A medical treatment for pyometra may be an option in some cases. Do be aware that the success rate is variable, carries considerable risk, and potential complications. Prostaglandins may be used to lower the blood level of progesterone, relax and open the cervix, and cause the uterus to contract and expel the bacteria and pus. This treatment is not always successful and as mentioned carries other risks so weigh this option very carefully with your veterinarian.
  • If the bitch with pyometra does not obtain immediate medical treatment the toxic effects of bacteria can be fatal. In a closed pyometra the uterus could rupture, spilling the infection into the abdominal cavity which may also be fatal.

And, after all this has been said I am still thinking that the spay procedure that saves the ovaries and removes the uterus sounds like a very promising option? Unfortunately, it appears that only three clinics in the U.S. perform this type of spay. Most importantly, talk to your veterinarians people, then make informed decisions for the Gordon Setter girls in your life.

Why all the fuss about inbreeding?

I’m sharing another great article from the Institute of Canine Biology with you today on breeding and genetics written by Carol Beuchat PhD.  This blog and Carol’s writings offer a wealth of information for the serious dog breeder and I’m going to be

recommending quite a bit of reading from this site for just that reason.

In this article Carol covers the topic of genetic disorders and the choices breeders face when planning a mating. She says “Breeders know that they can use inbreeding to concentrate the genes for the traits they prefer and to increase the predictability of a breeding by reducing variation in the offspring. But breeders have no way to increase the good genes but not the bad ones through inbreeding. (There are ways this can be done, but not using inbreeding.)”

As breeders we simply must take time to learn and understand genetics.  “You will hear people say that their lines are “healthy”, or that a particular problem is “not in my lines” This is a quote from Carol’s blog that I’ve heard oh, so very often, from many, many breeders over the years. Before you assume that you are safe to use statements like this as fact, read this article. It will indeed help you to more fully understand what lies beneath the surface.

Is she…or isn’t she?

The day after the breeding is done the question “Is she or isn’t she?” starts stomping through my my head while I pace two steps behind the bitch watching her every move for any sign or signal that she is pregnant. I can’t help myself, I want instant gratification! Guessing that I’m not the only Gordon Setter breeder who spends an inordinate amount of time waiting and watching for any indication that the pregnancy exists I thought I’d share a few reference sites here that provide excellent information on the various methods of determining pregnancy in a bitch, with the use of ultrasound being my primary topic. All of these are diagnostic tools your vet will use not something you can do at home…well, I guess if you’re a vet you could be a DIYer!

I’m hoping you’ll all chime in below with comments on your preferred methods or your personal experiences to add substance to the conversation, as well as to provide new or additional links to share with our readers!

Janet Floss published Pregnancy Determination in the Bitch , the article is found at the University of Missouri Extension, College of Veterinary Medicine. She includes the use of Abdominal Palpation, Radiography, and Ultrasonography in this article. To go to the site to read the article simply right click on the bold printed article and the link should open.
