YOLO Posted February 28, 2013 Share Posted February 28, 2013 Yes, this is another “desexing” thread. When we get another dog or puppy I am contemplating a bitch, and am in two minds. Please, I don’t want another thread on the pros or cons of desexing. These two diseases are the most forceful arguments for early desexing of a bitch and I would like to know just how prevalent they really are. One study I read said Pyometra occurs in 25% of entire bitches, which seems extraordinary?? Link to comment Share on other sites More sharing options...
Podengo Posted February 28, 2013 Share Posted February 28, 2013 We had a retired breeding bitch from a breeder and spayed her at 4 years old, she developed urinary incontinence within 6 months, and at 7 years old we noticed a lump on her breasts... She had mammary cancer, was given a few months to live as it had spread all through her, she died 2 months after hee 8th birthday. All the other dogs of this breed we have has were spayed at 6 months, never had incontinence issues. Link to comment Share on other sites More sharing options...

WreckitWhippet Posted February 28, 2013 Share Posted February 28, 2013 I've never had a bitch with pyo but it's something that you need to be mindfull of. If you aren't going to breed your bitch then letting her have a couple of seasons to mature and then desexing would be an idea to think about. As for mammary cancer, I'm yet to have one of those either but again it does happen and you need to know the signs Link to comment Share on other sites More sharing options...
Poodle Mum Posted February 28, 2013 Share Posted February 28, 2013 There's no point in a bitch having any seasons if you aren't going to breed her. Each time she has a cycle there is the possibility that she will have a pyo. It also increases the chances of mammary tumors. Link to comment Share on other sites More sharing options...
D'smum Posted February 28, 2013 Share Posted February 28, 2013 I had no idea how common the were until i started working at a vet clinic. Wow. I couldnt contemplate leaving a bitch entire after that, unless specifically for breeding (unlikely for me). Link to comment Share on other sites More sharing options...
Chezy Posted February 28, 2013 Share Posted February 28, 2013 only recently found out about pyo but now I know several people that have had it happen to their bitches, my brother being one, i now know it is quite common . I have mutts and they have always been desexed , so it has not been something i have had to deal with tg, after rushing my brothers bitch to vet I would never reccomend leaving a bitch undesexed .

Marion 01 Posted February 28, 2013 Share Posted February 28, 2013 I have unspeyed bitches here, there are 8 ( two of them are pups who will be desexed at 6 months, the others range in age from 10yrs, 12, & 13) at the moment, no sign of pyo but one had a mammory strip last year and now basically has no boobs at all.

Dory the Doted One Posted February 28, 2013 Share Posted February 28, 2013 I've never had a pyo, had 1 mammary cancer in a bitch whose mother also developed them. We removed my bitches lump, it was only pea sized but I wanted it gone and thank god I did! (she was 4yrs when we found it)I checked her weekly and she died at the age of 11yrs for a non related issue. She was a Rottweiler. I don't think you see a true picture of the problem in a Vet Clinic. Remember in a Vet Clinic we tend to see them when they are sick. I've seen plenty enough bitches who have not been desexed live long happy event free lives. That all said. If you're not going to breed then desexing would certainly be something I recommend. As to what age? I'm still in two minds about that. I'm inclined to want my dogs to reach maturity before doing it. But as I currently have an already desexed, rescue dog...well...I haven't been in the position to have to make the decision. Link to comment Share on other sites More sharing options...
*Lolapalooza* Posted February 28, 2013 Share Posted February 28, 2013 As a kid we had a dog who was never desexed (never bred from, I have no idea why my parents didnt desex her) she lived to 17 no pyo or breast tumours. My sister had a rottweiler who was never desexed (never bred from, again dunno why she wasnt desexed) no pyo or issues. Lived to 11 died from abdo tumour. My first showing female was never bred and was 6 before being spayed, no issues dies at 8 from osteosarcoma. My first girl for breeding was bred at 2 did not get pregnant, bred at 2 1/2 didnt get pregnant (all done with prog's and semen checks) third time I tried frozen semen and pyo and spay....gah!!!! I have a bitch who has just turned 7 and has lost a boob from mastitis but is fine otherwise. She will be spayed shortly. my other sister had a pyo with the one stafford she left entire and she was spayed at 6 (she wasnt blue or bred from ;) ) I hope to hell I never have another pyo It was bloody awful.

german_shep_fan Posted February 28, 2013 Share Posted February 28, 2013 I wonder if any research has ever been done to determine if a bitch's mother or grandmother suffered from Pyo if they have a increased risk of also contracting it? As it is different from cancer ect it could just be bad luck? Link to comment Share on other sites More sharing options...
persephone Posted February 28, 2013 Share Posted February 28, 2013 AS Pyometra is an infection ... I would think heredity plays little part in it? We have had 3 bitches with pyo over the (many, many) years, a couple have had mammary tumours .. while they may not be common , they are a life threatening problem ....

Diva Posted February 28, 2013 Share Posted February 28, 2013 I have never had pyro or mammary cancers in my entire girls, the only one who got a mammary tumour was desexed as a young adult. I am very alert for signs of pyro, especially in the higher risk period after a season. I am not particular concerned about mammary tumours, I have my hands on the dogs so frequently I pick up any lump or change very early. The risk of pyro to me the most compelling reason by far for desexing. I still choose not to though. Link to comment Share on other sites More sharing options...
stormie Posted February 28, 2013 Share Posted February 28, 2013 I got these stats on Mammary cancer from a Repro course I did recently... Desexing: before the first heat results in a 0.05% lifetime risk of developing mammary cancer. After 1 heat = 8% lifetime risk After 2 heats = 25% lifetime risk After 3 heats = 50% lifetime risk After 4 heats = greater than 75% lifetime risk Link to comment Share on other sites More sharing options...
Diva Posted February 28, 2013 Share Posted February 28, 2013 (edited) Stormie, are they benign or malignant tumours you are talking about? Either way I must be 'winning the lotto level ' lucky, given all of mine who never had it and died entire, but I am interested what sort the stats are for. Eduted: just did some googling and came up with a 25% risk after four years of age for entire bitches getting any sort, benign or malignant, with some breeds more prone than others. That fits much more with my experience. Obesity is listed as a risk factor, which might explain part of my girls' luck so far.

espinay2 Posted March 1, 2013 Share Posted March 1, 2013 Have not had a case of pyo yet, touch wood, but one bitch (never bred) speyed at around age 7 had a very spongy uterus when they did the op. Basically cystic endometrial hyperplasia (which is associated with an increased risk of pyometra) This is what it looks like: http://research.vet.upenn.edu/SystemicPathology/Exam4/CommonSmallAnimalLesions/tabid/3649/galleryType/SlideShow/ItemID/591/AlbumID/56/Default.aspx This in particular is some info very worth reading: http://www.vetnext.com/search.php?s=aandoening&id=73057642019%20318 Note the following: "Repeated exposure of the endometrium to high concentrations of estrogen followed by high concentrations of progesterone in the absence of pregnancy leads to cystic endometrial hyperplasia". Some discussion of the issue in these links. It is in the context of breeding, but still relevant : http://www.everythinggolden.com/new_page_195.htm http://www.veterinarypartner.com/Content.plx?P=A&A=1224 For those interested in this subject too, note the upcoming (free) course which should address just these sort of issues both for breeders and those considering the pros and cons of desexing or when to desex: https://www.coursera.org/#course/theriogenology Link to comment Share on other sites More sharing options...

Out of those though, they say that about 50% will be malignant. Link to comment Share on other sites More sharing options...

Mostly I am reading one in four lifetime risk if never desexed. I am now deep in research into risk factors, didn't know it was breed related. I have added them all up, lol, and I have owned 10 bitches across the years, of two breeds. One incidence of benign mammary cancer in a bitch desexed as a young adult. One other desexed at an older age for another issue, no cancer. None of the others desexed and no mammary cancer or pyo.

Sandra777 Posted March 1, 2013 Share Posted March 1, 2013 (edited) Pyo I have known :) 5 year old, had had one litter & missed on previous heat (to a dog with poor semen quality & count) had been mated (different dog) & scanned as pregnant. Speyed (1kg ueterus removed from a 14kg bitch so pretty serious). She's 9 next week and no tumors. 1 year old maiden bitch, treated with ABs, went on to have 6 litters. Had benign mammary tumours which developed when she was 9. PTS at 13 - stomach cancer. 11 year old, had had 4 litters. Treated with ABs. She was on one of the injections (probably Depovera, it was a while ago), increased the frequency of the injection to three times per year. No tumours. PTS at 14 after breaking her pelvis leaping to catch a sparrow (which she caught & ate) 8 year old had had 2 litters but only ever conceived 2 pups each time.... Speyed. Had mammary tumours removed at 9, one malignent, rest benign. PTS at 14 - lung cancer (we smoked) 8 year old had had 3 litters (lost the entire first litter "fading puppy"). Very mild infection, could have been treated with ABs but no reason to so was speyed. No tumours. PTS just before her 16th birthday, just generally unwell and life no longer good for her. Other info.... The 1 year old was the grandmother of the sire of the first 8 year old. The two 8 year old's had the same dam who cycled every 3 months and lost two complete litters to fading puppy syndrome. The only daughter of the first 8 year old had three pups in her only litter, all fine. The second 8 year old had 2 daughters who were bred, one lost part of two litters "fading puppy", the other had three litters all fine. The second of these bitches was speyed at 8 and is now just over 13 - no tumors, the first was speyed at 5 and last I heard (2 years ago @ 11) was fine - no tumors. The only other bitch I have had with tumors was a daughter of the one who broken her pelvis. She was speyed after three litters (no issues at time of op) and developed very large but benign tumors when she was 11. PTS at 14 with fluid-retention issues. These are all Staffords, which tend to be considered 'prone' to some types of cancers & growths. Edited March 1, 2013 by Sandra777 Link to comment Share on other sites More sharing options...
