Why....if a purebred dog has pups fathered by a mutt, the purebred is then "ruined" for producing purebreds?

Question

It doesn't make sense to me that after a dog has had a litter of mutts she can no longer be mated to a purebred dog of her breed and produce purebreeds. Can someone explain this to me?

My golden retriever is spayed so this isn't an issue for me....I'm just curious.

Answer 1

That is an old wives tail.

A previous mating has nothing to do with a future mating.

My guess is way back when someone had a purebred, she accidentally got bred by a mix. Later the person bred to a purebred. What the person didn't know was that his female was sneaking around, when the pups were born there were some mixed breeds. Sooo, they blamed it on the previous litter.

What they didn't know then was that a single litter of puppies can be sired by more than one stud,

Answer 2

This is a fallacy. The fact of the matter is, if during a different heat cycle, the girl dog (yahoo won't let me call her by the real name) is bred by a dog of her own breed, she will give birth to pure-bred puppies. The issue is, no dog should be bred unless it is an exemplary example of its breed, has had all of the appropriate genetic testing for its breed (as in Great Danes are prone to cardiomyopathy, thyroid issues, hip and elbow dysplasia, so should be tested to be sure they are free of these issues), is of the appropriate age, and the breeder has homes already lined up for the puppies to come. The breeder should also be willing to take back any dog that is purchased from him/her that the new owner can no longer keep. It's a very big responsibility to bring a litter of puppies into the world, and should be taken seriously. There are over a million dogs put to death yearly due to not having a home. But in answer to your original question, you're correct. A purebred dog bred to another purebred dog would have purebred puppies. And good for you for spaying your girl.

Answer 3

Glad to see that your dog is spayed! There are to many dogs out there as it is that have no homes because of all the breeding so thank you! . Either way, mutt or purebred, their both loving,caring, and are ''mans best friend'' purebred or not. If she has pups SHE is still considered purebred though in my opinion and as in many others as well. The pups may not be..but she still will be. Even though she has had pups and mated with a mixed breed she can still produce the purebred pups if bred with another purebred. She's still the same. But as for the pups, purebred or mixed, they are both loving :) Hope this answers your question and helps :) Good luck! Kelly

Really interesting read... I have not finished yet (only skimmed), but decided to answer it anyway, because I already have in my mind the basic answer to you question. Mutts vs Purebreds which is safer? Well - Any dog can bite. We all know that! But in my opinion it is not nearly so much a breed issue as a training, socialisation issue. People get so hung up on the breed! When there is so much more to it then that. Yes some breeds may more likely to bite and that question does need addressing. But sometimes I think it would be better, instead of the first or main question being asked after a bite being: What kind of dog was it? Would be to interview the owner and ask them a few more pertinent questions. What experience have you had handling and training dogs? What level of training have you and your dog got to? How long have you had dogs? Have you ever had a dog that has bitten before? How often do you socialise and exercise your dog? Why did you get this particular breed of dog? You may not always get honest answers, but you would get an idea at least. Besides, I wonder how many people say “a GSD bit their child”… when in fact it may have been a GSD x Golden Retriever. That would put it not only in the Mutt category, but the Golden Retriever box too!? Yet I highly doubt anyone would say “a Golden Retriever bit my child” when it is a dog of that mix. I think we would suddenly find the results begin to show, that ANY dog, without proper care, training, socialising and so on, is more likely to be involved in an incident, then those that do have those things. Instead of just labelling the GSD or Dobe as one of the worst... Perhaps a bit of time assessing the owner of said dogs and what role they played in the incident, would be of benefit. People are also more likely to report a GSD or Dobe or Rott bite, then something else. I know of an incident recently involving a child I know who was bitten by a Whippet in the face... left a bad scratch and only just missed his eye… but no report was bothered with. Had it been a “big aggressive breed”, I have no doubt there would have been a report made. As a long time Dobermann owner (over 40 years of Dobermann ownership in my family). I will say that none of my dogs or my families dogs, have added to those statistics. My dogs are also out in the public a lot, I take them to parks, the beach, fates and fairs when I go to browse and they get a lot of patting, friends houses and so on. Plenty of people and children to bite in all those places, yet no incident in all those years? Why? Because my dogs are well trained and socialised. The way every dog (not just certain breeds) should be. I come from a largish family, loads of nieces and nephews, cousins and so on… all of whom play (supervised) with my dogs, none of whom have been bitten. I really do think it comes down to management of the dog by the owner… when managed properly, incidents should dramatically be reduced. We can never rule them out completely, because we cannot control EVERY situation. No differently then if you drive your car carefully, you will be less likely, (not absolutely), to be involved an accident.

Answer 5

There is absolutely NO truth to that what so ever!!! A purebred dog can be mated to another purebred dog of the same breed and produce a registerable purebred litter. She is not "ruined"/

Answer 6

That must be an old wives tale....that's not true. Maybe it comes from the reputation of the stud. If anyone hears he fathered a litter of mixed breeds, maybe that hurts his reputation??? (Just a guess) But I don't think there is any truth to that.

Oops...interpreted the question wrong....I think it goes both ways....either a female having a litter of mixed breeds or a stub fathering a litter of mixed breeds.....there's no truth that the dog would be ruined.

Answer 7

You cannot ruin a dog. the sperm is produced by the cell inside the male dog. Where they go after they are produced and removed from the body does not affect the biology of the male dog. The same goes for female dogs. Pregnancy does not change the egg producing apparatus of the dog.

Answer 8

Good question. I've never heard of a dog being ruined because of a mutt litter. Maybe people are just stuck up and obsess about their dogs being perfect.

Answer 9

it's just a misunderstanding, they things is a purebred mixing with ANY other breed, presents the risk for complications (especially in dogs with drastically different physical dimensions) that's the only problem i've ever heard of.

Answer 10

The only ones that believe that are people ignorant of dog breeding and reproductive results.

The female isn't ruined because nothing in her genetic makeup was changed. Sperm went into eggs which turned into puppies which were born. End of story. Nothing about the mother's DNA changed at all.
