EmiLeigh Posted November 22, 2011 Share Posted November 22, 2011 I have been having this 'discussion' with my partner a while back about the possibility of dogs 'throwing back' to previous matings, and a friend recently bought up the topic again today. So tell me, if you have a pure bred bitch and she mates with a mutt, is she 'ruined' for further purebred breeding? Woudldn't that mean a bitch would have to store live sperm in it for that period of it for it to be physically possible? Plus that means if you were to mate a purebred bitch wtih one stud dog one season and another stud dog another, she could have pups from the previous dog, meaning that no breeder could garantee the pup is of the genetic lineage they say it is if they have bred their dog with other studs in the past. Right? Look forward to your answers Link to comment Share on other sites More sharing options...
whiskedaway Posted November 22, 2011 Share Posted November 22, 2011 Fresh sperm only lives for 11 days, so no, it's impossible for that to happen. Link to comment Share on other sites More sharing options...
Kirislin Posted November 22, 2011 Share Posted November 22, 2011 I dont believe that is possible. It's an old wives husbands tale Link to comment Share on other sites More sharing options...
WreckitWhippet Posted November 22, 2011 Share Posted November 22, 2011 (edited) Nope impossible ETA: the words " throw back " more often than not refer to characteristics of ancestors. For example the pups were a throw back of the Grandsire or the line might has produced a particualr type or colour for generations and then an odd one out pops up.

dancinbcs Posted November 22, 2011 Share Posted November 22, 2011 In a word NO. Absolutely as impossible in the dog as it is in humans. Link to comment Share on other sites More sharing options...

EmiLeigh Posted November 22, 2011 Author Share Posted November 22, 2011 Looks like I won that argument :D My partner thinks he has seen this, but I think he may have just seen a bitch who got pregnant to two dogs in the one mating(??) though he is convinced the bitch he saw didn't have the chance to mate with another dog. Thank you everyone for your answers. Link to comment Share on other sites More sharing options...
Weasels Posted November 22, 2011 Share Posted November 22, 2011 (edited) Long-term sperm storage can occur in some reptiles and some invertebrates (wasps, worms etc.) but not dogs, or any mammals as far as I know. Multiple matings sound like the culprit. Did you win a beer at least? ;) Edited November 22, 2011 by Weasels Link to comment Share on other sites More sharing options...

Yup, that can definitely happen! Either that, or immaculate conception ;) Link to comment Share on other sites More sharing options...
tdierikx Posted November 22, 2011 Share Posted November 22, 2011 In rescue we see quite a few litters that have obviously had more than one sperm donor... but it would all be from the same season in the bitch. T. Link to comment Share on other sites More sharing options...
