Mutts/Hybrid dogs infertile?

Question

So I wanted to know if it was true that mutts are infertile. Someone told me that it was true, but I don't believe it! It doesn't make any sense. And someone else said that if 2 mutts of the same type of breeds mate..then it's possible. I'm puzzled!

Answer 1

Wouldn't that be fantastic, if mutts were born sterile?

People could enjoy the mutt-ly types they love, without worry of making dozens and dozens more!

Answer 2

No, thats false.

Look at all the people breeding labs to poodles, to cockers, to who knows what.  

Answer 3

Mutts are fertile. So are wolf hybrids.  

Answer 4

That's false.  

Answer 5

Dog are all the same species, therefore can inter-breed and have fertile offspring.

It's only hybrids, meaning 2 different species (such as donkey + horse = mule) that are sterile.

.

Answer 6

I wish that were true, but it isn't. All dogs are the same species, they just come in lots of shapes and sizes.

Answer 7

Mixed breed dogs are not technically "hybrids".  A Hybrid animal is the result of breeding 2 different species.  Such as when you breed a horse and a donkey, you get a mule.  A mule is often infertile.

ALL dogs are the SAME specie!  There are different variations among the specie from selective breeding.. but they are still the same (poor example, but its like how we have people of different races with different skin color, hair color, etc.. but we are all still people and all still capable of producing children, providing there are no infertility problems).  

If a dog is infertile, its not because its a mix.  Even purebreds can be infertile.  Infertility happens for other reasons... disease, injury, or even some other genetic condition that has nothing to do with the dog being pure or mix.

Most purebreds are the result of selectivly breeding certain other breeds together and breeding for specific traits.  Yes, essentually, they all started as mixes.  So, if you do believe that theory, how is it we get purebreds that are capable of reproduction if mixes are infertile?

Any breed of dog can mate and produce pups with any other breed of dog..  it doesnt matter if the dog is a mixed breed or pure.

Answer 8

Someone told you wrong.  Mutts are very fertile unless they are spayed or neutered.

Answer 9

Cross bred dogs are NOT hybrids because dogs are the same species.

True hybrids, animals like mules, tygons, ligers etc are usually infertile.

Answer 10

No,it not true.Why do you think there are so many mutts? Do you think that every one of them came from two purebreds? Mutts are very fertile.

Answer 11

Mutt's are not hybrids.  You get a hybrid when you cross two different species.  All dogs are actually the same species.  They're just different varieties of that species.

Most hybrids are sterile, but there are many that are not.  Mother natures plays by her rules, not by the rules set down by biologists.

Answer 12

Pure Bred + Pure Bred = Pure Bred

Mutt + Mutt = More unwanted Mutts.
