can someone resolve this debate i am having with my partner

BOGUS!!!!

i know its such a strange consept i dont understand were he has got that idea from he can come out with some weird notions sometimes lol
 

You're right.  That jack russell's sperm went to producing puppies - it does not become part of the dam's DNA - she's still a purebred.

However, I would question why your sister wants to keep breeding this poor female.  She at least DOES know to wait a full year I hope?

yes she does no to wait, she is well looked after and will only go ahead with mating if she is in good enough condition to. she is regularly vet checked and there are a lot of people who are already interested if it goes ahead so they will have good homes.

Its not going to make you sisters dog any less of pure breed.  I have heard that myth myself.  However, the long term health of the pups (designer dogs) she is making could be questionable. 

My question would be do these people even get what a responsible breeder is???????
Did they sell the other pups as jackcocks or cockjacks and what the heck was the purpose of that breeding other than to put the bitch at risk producing a mutt litter? Tell them to talk to a responsible Cocker breeder about why they don't yet have the knowledge to be doing this at all. [:@]

jackcocks or cockjacks

 
I was thinking "Cocker Jack" - like a Cracker Jack without the toy prize

My brother had a pure English Bull...got "caught" by a terrior of some sort....and was told he could not breed her for pedigree pups because of it...so I would have gone on the side of your partner in the debate.

OK, first, I realize that this is your sister doing this and not you, so my apologies in advance for the rant, but dag nab it.  Cockers happen to be a breed near and dear to my heart and back yard breeders are RUINING the breed by just willy nilling breeding anything that has reproductive organs.  There are a LOT of genetic conditions in cockers that have to be very carefully screened to reduce the possibility of passing those conditions on to another generation.  For example, if GRANDMA developed epilepsy later in life, not due to an injury, her offspring shouldn't be bred because now we know that a genetic weakness exists for epilepsy in the lines.  Does your sister even KNOW the medical history of her bitches parents, let alone grandparents?
 
Seeing the vet regularly isn't testing for genetic weakness.  Seeing the vet regularly isn't proving the dog in a venue to be absolutely certain that she DESERVES to be bred.  Only the best of the best in any breed should be used for breeding.  Not just because the dog is cute, not because lots of people are interested and the pups will have good homes.  Seeing the vet regularly doesn't insure proper temperment.  This willy nilly throwing together of dogs is WHY we have "bratty" cockers, or cockers with "attitude".  In many cases it is not totally the owners fault for not properly training, it is the fault of the backyard breeder who didn't think about all the aspects to insure a healthy and stable animal.
 
I'm sorry to rant.  But this kind of ignorant and irresponsible behavior makes me sick to my stomach.  Please tell your sister to educate herself and do some research before she mates her bitch again.

Yeah, what SHE said....[]
Wasn't anyone else even tempted to say the female couldn't be bred again and was "ruined"?[8|] I know I was.
 
I know you're asking about your sister's dog and thisn't meant to be a slap at you, or at her, but this type of breeding is why and how dogs end up being killed in shelters.
 
Please urge your sister to contact the owners of the existing litter and offer to take the dog back at any time in the dog's life for any reason. Suggest she check in with them every year to make sure the dogs are okay and hopefully none of these dogs will end up in a shelter.
 
If she isn't willing to be responsible for the pups for the rest of their lives then she should seriously re-consider allowing her dog to have any more pups.
 
 
 

my question has always been where the heck did this myth spring from and should we even be dispelling it!?!?
i mean think about it for a second or two.... maybe three....
top of the line breeders are often thought to be a bit snobby, but you might say that they are looking out for their breed.
if a dog is covered by a different breed and produces mutts for some silly reason its often frowned upon, even 60 to 70 years ago. the pups are curs, mongrels, useless in the pure bred dog show world.. which might make some people angry that its happened to them.
i mean .... someone gets a bad haircut they say "its ruined" even though hair grows back... if a bitch is bred to by a mutt then she is ruined.... for at least a year or two. the breeder has missed several opportunities to show their dog and win ribbons, and to have the chance to breed another top of the line stud.
so if someone mentions that they have a notion to do this cross breeding, or has already done it.... another person might say "i wouldnt do that if i were you. you'll ruin the bitch!"
perhaps its over reacting, but in a good way if your goal is to breed and show.... this myth might also help curb some useless mixed breeding.... but in turn it can also result in some breeders disposing of the so called "ruined bitch" in a not so nice manner.....

Me too. My dad's friend passed away about 3 years ago and we took in his Collie. She was a bit scared of people because before my dad's friend had took her in, she was abused because she mated with another breed of dog and wasn't able to have pedigree pups anymore. I've always wondered about it, but I've just stuck with it being true. It sort of seems right to me. That's just my opinion though.

What makes a dog a "pedigree"?

I don't understand how this works genetically.  Does cross breeding a pure bred animal changesomething so that breeding her say 2 years later with another purebred animal makes her pups not purebred somehow? 

You just randomly end up with a crossbreed puppy from the male that produced a litter in her 2 years ago? 

******

AND why is it so frowned upon to cross breed?  Considering all these pure bred animals were developed by crossbreeding for desired traits in the FIRST place.  Like, I have a serious fondness for the dog produced by crossbreeding dobermans and rottweilers.  Awesome looking dogs.  And the ones I've met were smart, healthy, and just great dogs.

What's wrong with that?  Personal distaste?  Or is there an honest valid reason why doing it NOW is bad but doing it to THEN to CREATE the breed that is NOW so wrong to cross breed was good?
