Do your breeding females eventually get cancer?

@sqs1 Look here's our experience;

My husbands been breeding for 20 years now and I've been in it for 10 years. We specialise in medium breed dogs.

We've seen alot of stuff over the years, since I saw it mentioned, we've had a few pyos luckily ours were open and we haven't had to spay any bitches from them but we learned alot. Some bitches need antibiotics from the get go of breeding and others don't. Also breeding the heat cycle after a pyo definitely seems to stop another pyo.

Note that all our unspayed bitches were bred at some point in their life although a handful never took. The average Lifespan of our breed is set at 12, most of ours live between 12-14. A handful lived longer. A handful passed young.

With regards to cancer, I'm torn. We've had pet bitches who were spayed young, die from cancer and we've had adult unspayed bitches live to 15 and die from natrual causes. But over all the years and the many, many dogs we've had I will say it appears that once a dog gets to around 12-13 they almost always in our case get cancer or kidney failure. We've tried variations of many things, diet changes, supplements, different genetics etc. but it has never seemed to change much and this is with the males too. Often we have seen prostate/testicular cancer in our males as well as they enter their late senior years. From our experience and also from what our Vets tell us, it's almost inevitable for dogs to get cancer in their late senior years and sometimes people don't even realise their senior dog had cancer.

So do I think unspayed makes a difference. Yes and no. I will say I've seen more mammary cancer in unspayed bitches than spayed. But in regards to the cancer I've seen overall it seems to even out to making little difference overall.

There is one thing I found in our years. We got a bitch from a line that we loved and she was lovely, but in the end she got mammary cancer and despite our best efforts of spread and she died of cancer. But what was fascinating was her in her litter, 3 of her sisters all died of mammary cancer and one of her other siblings died under strange circumstances which I think was likely cancer. Now one of her sisters was spayed young too. Which leads me to think there was a huge genetic component there. Luckily for us (although at the time we were devastated) we never did get any pups off her, as we got her when she was a bit older. She was a brilliant dog though but yeah I definitely think genetics plays an even bigger role than we think.

Overall I think all dogs get cancer when they reach a certain age, its inevitable as the cells can no longer replace themselves correctly it's bound to happen. But I do think there can be genetics at play for certainty and some lines are way more predisposed which makes selcting your lines and knowing their history super important. And I think unspayed and unneutered dogs have a slightly higher risk of cancer of reproductive organs for sure. This is all on our own experience. Other breeds might be completely different. Hope it helps.
 
@gideondavid40 That helps a lot, thank you so much!! It makes sense. My mom is a nurse and she’s seen a lot of human death over the years, including in hospice, and her mentality is that everyone is going to die of something at some point and it isn’t worth worrying about beyond doing the responsible things you’re supposed to do to take care of your dogs.

Cancer happens to a lot of animals eventually if we live long enough. And my dogs are well taken care of. The majority are toy poodles, who tend to be able to live 15 to 20 years in many cases. It’s unlikely that we won’t see some of them get cancer as they age. And it could be any type of cancer, not just reproductive.

That definitely makes me feel better that it’s more of an overall risk due to aging than a certain death sentence from mammary cancer at a young age. I will get them all spayed and neutered when they’re past reproductive age so ovarian, uterine, and testicular cancer probably won’t be a problem.
 
@sqs1 I’m not a breeder, but the general issue is an unspayed female that never gets pregnant is at increased risk of cancers. Its ’use it or lose it’, and the risk of pyometra in an unspayed unbred dog is unnecessary.
 
@sqs1 A lot of research says that if they don't breed they'll have a bigger chance to develop cancer eventually.
I'm still a new breeder as well, but when the matriarchs "retire" I'll get them spayed, for health reasons ♡
 
@hovi Well, at least I am breeding them then lol. I have a 10 month old toy poodle puppy who I kept from a litter that I don’t intend to breed. I planned to get her spayed before her first heat, which for toy poodles is supposed to be between a year to a year and a half old but she’s having it now. Oops. Ironically just a month before I intended to take her to get spayed. She is probably the dog I’m most attached to out of any I’ve ever had so I’m a little concerned about that for her.

Of course I plan to get them all spayed when they retire too. I have a 5 year old who didn’t do well with labor and delivery so she was spayed as soon as her pup was weaned. She still had heats for about 3 years though.
 
@sqs1 Heats should stop after spay, if she still had heats it's likely that they didn't remove all the organs, even a small portion of ovary can cause heats.
 
@marriage007 Oh no what I meant was I hadn’t taken her to get spayed yet because she is having her heat quite early for a toy poodle. I was planning to have it done next month before she turned a year old. I haven’t called and asked if they can do it during heat, I figured I might as well wait until it’s over now.
 
@lovinggod16134 Would you like to give me any actually helpful information or do you just want to criticize other people? It does me no good for you to just say “this is wrong” because assuming I believe that you’re right even though you did nothing to back that statement up I don’t learn anything.

I didn’t make this post with the intent to have people argue, I made it to hear real experiences from people more experienced than me. Which I haven’t actually gotten any of yet, but I would also take accounts from people who know something on the subject if they will give me any indication that what they’re saying is correct.
 
@sqs1 My parents waited 2 years to spay our dog. She eventually got lumps in her breasts and had to get them surgically removed. At 7yo she had to be put down because she started randomly attacking our other dogs and killed one of our chihuahuas. She also went blind about a year before we had to euthanize her. I found out she had a brain tumor later. Though they could have been unrelated, cancer loves to metastasize and it’s very likely the two tumors are linked.
Cancer is a rare disease but it can happen and when it does it’s devastating — our dog was taken from us years before she died.

This is not to try and convince you to not breed your dogs, but make sure you are prepared for the reality of the situation if something happens.
 
@diancuk I’m sorry you went through that. It’s a terrible thing to experience.

It’s really too late to do anything about the risk for my breeding dogs at this point. They’ve all had multiple heats. I initially did not want to breed for multiple reasons, this one included, but my mom made that decision and I didn’t have a choice in the matter. I just wanted to know how commonly breeders actually see it over the years and over multiple dogs.
 
@sqs1 Definitely was one of the more upsetting experiences I’ve had... She was a good dog before she lost her mind.

Like I said in my OG comment, I’m not trying to bash any breeders. I just wanted to share my experience and emphasize that there ARE very valid clinical reasons to have your dog spayed before their first heat.
I know everyone has been up in arms about letting them have their hormonal cycles but I just haven’t been able to find substantial peer reviewed research papers to support those claims, only unreviewed claims from researchers that carry 0 weight until they’re actually published. I work in healthcare and I am very concerned with the amount of pet owners and even veterinarians I see believing these claims without proper research. It reminds me of the patients I talk to (I work in human healthcare) who are unable to understand why unsubstantiated claims are dangerous…
 
@diancuk Oh yeah, the only argument that I have seen with evidence to it is that being spayed makes them more likely to gain weight due to a slower metabolism. Which is something you can control if you are a responsible owner. You cannot control cancer.

Someone else on here is saying that getting them spayed early puts them more at risk of bone cancer…which is something I’m going to have to research because I do have one young female dog who I’m not planning to breed.
 
@sqs1 Yeah… I’ve tried to look up those claims and I can’t find like. Actual papers. Just random news blurbs on for profit websites about it :/
If i knew where the info was coming from I’d be more inclined to believe it… It sounds like you have a pretty good head on your shoulders, though! You’re being as responsible as you can be and your dogs health is at the front of your mind. That’s all you can ask for in a pet owner.
