Line breeding?

Question

VET TECH shouldnt assume that I let this happen. Now tell me about line breeding, or did you sleep through that class?

Answer 1

Please listen to the advice from 'A Veterinarian' on your second post..She really IS a vet and gave the very best answer..

With the one genration of inbreeding..meaning that the male was not also inbred, then your pups should be fine..Be sure and give mom quality kibble and prenatal vitamins..You can get them at any pet supply, or from your vet's clinic without a prescription..

Answer 2

For the record, they don't teach classes about breeding dogs. You have to learn it, preferably from someone who knows what they're doing rather than trial and error.

I must also point out that Veterinarians, while excellent at treating animal health problems (if they're good, anyway), do not necessarily know anything about genetics or dog breeding. They don't teach that in Vet School, either. I've known plenty of good vets who were utterly ignorant when it came to breeding dogs, beyond knowledge of genetic disease and how to treat it. So demanding that only veterinarians answer your question is not necessarily the path to success.

The people who have equated Line Breeding and Inbreeding in previous answers to your (rather antagonistic) posts are wrong. They are NOT the same thing.

Others have posted the differences between the two, but the bottom line is that the litter you are expecting is INBRED, not linebred.

This doubles recessive genes, which means that you have a greater chance of seeing recessive-genetic health problems in the puppies. Depending on the breed of dog, this may include hip dysplasia, juvenile cataracts, entropion, corneal dystrophy, luxating patella, heart problems, etc. -- again, it depends on what the breed was predisposed to.

I'm going to go out on a limb, here, and assume that the father and mother of your puppy were not tested for the common genetic problems to which their breed is predisposed. So basically you have no idea whether or not any of these problems will show up, anyway, since you have no idea whether or not they exist in your dog's bloodlines. If they do, this breeding will likely produce them.

Inbreeding can be a useful tool for the experienced, knowledgable breeder. Personally, I would never breed anything closer than half-Uncle to Niece/half-Aunt to Nephew, or grandkid back to grandparent. But that's just my viewpoint. There are plenty of books on the subject, if you really want to learn more.

If, however, you're just concerned about the here and now, and what this means to the imminent litter, then here is my recommendation, as someone who has been studying genetics and breeding dogs for 20 years.

1. If you can't spay the b*tch at this point, whelp the litter and INSIST that any puppies you sell be spayed or neutered. You have no idea what problems may appear in these puppies by breeding age, and you don't want to perpetuate that problem by letting (yet more) ignorant pet owners breed affected dogs.

2. Don't let this happen again.

3. Please consider spaying your little girl after the litter is weaned, in order to avoid exactly these kinds of problems.

Good luck!

Answer 3

All of my dogs are the product of line breeding (and we only have nine Champions here at this time), and most people have no perception of how line breeding is done successfully.
Most would assume that a stud dog is the foundation of successful line breeding, and this is NEVER the case. ALL successful line breedings are the blending of "foundation b!tches", or "out crosses" that are then bred back to the original line.
Inbreeding is a completely different thing and has no relationship to line breeding, but inbreeding is not without it's own merit. The common use of inbreeding is to identify recessive traits in a line. By doing a first generation breeding recessive traits become dominant (visible), and then can by selective line breeding and out crosses be culled from the line. I would also point out that the entire breed "Llewellyn Setter" is the direct result of the breeding of two litter mates.

Answer 4

Any good dog person knows most Techs know absolutely nothing about breeding. Even many Vets know little about it. The LAST place I would go for breeding advice would be a Tech!

Line breeding class, LOL!

Answer 5

Line-breeding is the breeding of animals that share common ancestors but are not closely related. For example the dogs may share a common great-grandparent.

Line-breeding is another way to help "set" or "fix" desirable traits. With line-breeding you breed animals that are related, but you are also routinely introducing genes from other lines into the genetic mix. It takes longer to fix the desirable traits this way, but doing so lowers the risk of those problems associated with repeated in-breeding. With a tight line-breeding you might find the same 3, 4 or more dogs showing up numerous times in a 5 generation pedigree

Answer 6

LINE breeding is the breeding of animals that are related. Not to be confused with INbreeding...the situation you have. When I look at pedigrees of dogs that are going to be bred, I may want to breed to another dog that has some of the same dogs in the pedigree. this can be way back in the 4th generation, and they can share many dogs in that generation...or maybe they share a common ancestor in the second generation. The DEGREE to which a dog is considered linebred depends on those common ancestors. If you were to inbreed, or have a "tight" line breeding, you would highly consider following with an outcross, which would be breeding two unrelated dogs. Outcrossing is also done to add some vitality to a "line" or to add other traits that are needed. Most breeding programs would center around linebreeding and outcrossing. Inbreeding can be done to "set" type, but has the risk of backfiring and resulting in a doubling of the less desirable traits.


Hey guys....she wasn't ASKING me for advice...she was trying to DIS me. I may be a TECH, but I DO know about linebreeding. And it is true that most vets do not. They do not teach about breeding in vet school, or tech school for that matter.

Answer 7

****LMAO!!!****
ANY time you post ANYTHING here,you MUST be aware that you open yourself to the the ENTIRE ***IGNORANT***WORLD!! Plus,a miniscule number of people who actually HAVE more than 3 brain cells connected

Honey,most VETS don't understand 'line breeding" (or in-breeding or SCATTER OR ....) let alone a TECH!!!

Answer 8

I bred canines for 30 years.
Here is a link that explains it all. Hope it helps you.

Answer 9

Well you're clearly not taking care of your dog well enough. How was it out of your control to let your PUPPY get pregnant by her dad? A puppy of 8 months should have constant monitoring since it's not an adult...and u managed to give it enough space to get it knocked up by it's dad. Unfortunately, anyone can have pets, it's so sad too. I wish your puppy and her puppies the best of luck, and hopefully they'll have a better home than their mother did.
