Is a curved back(topline) genetically passed on? I am still waiting for my female to go into heat (8 months since her last heat) and have found a third tiny stud (2lbs 10 oz.). Two of the three tiny studs have curved toplines. The male with a perfect back has only bred one female and her puppies died, so I am hesitant to use him. The other two have successfully bred puppies, but as mentioned have noticeably curved toplines -- is this passed on genetically or is this just common in tiny yorkies? |
I'm no geneticist or breeder, but I would say that a curved topline is definately genetically passed on. How else would a dog get this trait? :confused: Maybe someone with more experience could answer this question better. ;) |
A roached back/curved topline is a fault that should not be bred. Any breeder allowing a dog with this fault to be used for stud service is unethical at the least. This is a structural defect and can lead to further soundness issues involving hip/joint/knee problems and possible poor quality of life for this dog and it's offspring....not to mention the possibility of expensive surgical repairs. Please do not use a stud just because it is convenient. It can take much effort and research to locate a suitable and healthy stud with a solid healthy pedigree. |
back A bad top line is such a screaming fault..and you can not blame a stud for the pups dying..too many factors involved. |
I would never breed a dog with a bad topline. Sometimes you can't see the genetic faults, but it would be very irresponsible to breed a fault that you know is there. |
I concur...a roached back is NOT a desired trait and NOT something you want to breed. |
Thanks for your replies. The owner of the tiny male with a perfect topline was the one who actually told me that it is hard to find "tiny yorkies with a straight back" -- that's why I thought it was a trait associated with tiny yorkies rather than a genetic fault... Believe it or not I've been looking for a "suitable" stud for a year. I live in Saskatchewan, Canada - people population is small and so is the yorkie population. Not finding one, I tried buying a male stud myself (disastrous experience that I have already written about under breeder reviews (Chaffins, Oklahamo) ---My pricey (by Saskatchewan standards) promised 2-3 pound yorkie stud turned into a whopping 8 pound boy. YORKIEROSE: You're right about the puppies dying -- there could be many reasons. I forgot to mention that the same stud spent a week with two yorkie females that were in heat at the same time and got neither one of them pregnant -- my vet was hesitant in recommending to use this stud, so ... I guess I'm back to square one in my search!!! Any ideas anyone???? |
