To be fair all the breeds were crossbread with other breads to become what they are today. I still believe in keeping pure breds if only because you know what your getting.
An argument which really means nothing.
I have no problem with people who want to start a new breed (like the American Mastiff), recreate an old breed (like the Victorian Bulldog), or have an actual goal (like the Australian Labradoodle, which was created to give people with disabilities a helper dog that combined the well-known positives of a Lab with the allergy-friendly fur of a poodle).
I DO have a HUGE problem with people who just breed random mixes cause they think it would be cool (or because they’re too lazy/stupid to be trusted with an intact pet and can’t be bothered to police it). People like this make the worst backyard breeder look like the poster boy for breeder responsibility
Not all breeds were created from crossing other breeds, FYI, there are several ancient dog breed who have remained mostly unchanged from they way they evolved. And there is no real reason to create a new breed today that we do not have a breed for already, they are crossbred because people just want something different.
The lab poodle mix as a service dog was an experiment that failed MISERABLY. On average 1 out of 4 of the mixes would have the no-shedding coat of a poodle, of that maybe 1 of 4 would have what it takes to be a service dog. So maybe one dog out of 2 litters had what it took, thats an awful lot of castoffs.
There is a breeder of labramutts in Australia who proudly proclaims that she breeds over 500 a YEAR, not for service work, just as high prices mutts.
As for second gen cross breeds it would depend on if they used a lab or a poodle to sire the second gen, almost in which case you end up with a dog that is mostly poodle again, so why bother? If you cross a lab poodle mix to a lab poodle mix you usually end up with pups that look like the original 2 breeds. Same thing happens if you cross a pug beagle mix to a pug beagle mix.
Gage is the product of a not opps breeding I'm sure because when I got him at 7 months old there was another litter of them for sale around where he came from originally, he is a great dog but never in a million years would I have paid for a mutt, especially one from untested parents.
Like they say a fool and his money.
