Size difference in breedings

What's some opinions on size difference when breeding. Lets say a female thats 28-30 lbs and a male thats 50-55 lbs? I've heard some say it doesn't matter and vice versa. I know in some animals if the male is much bigger the female can have trouble giving birth if the offspring is big. I'm not doing a breeding but the subject came up at the last show I was at and I was curious about the opinions members on here would have so here it is.

 

This is a good question, I have tried to do some research on this subject an got mixed ''opinions''.

(This mite get a better response if posted in health section.)

 

in my opinion there are a lot more factors then just the size of the parents used. like how are they both bred, are they from the same line, how strong are they line/in bred, these factors and more all have an effect on the outcome of a litter plus you never know if they might click the way you think they might.

 

I am guessing you are having a little trouble grasping what this thread is about.

 

no i understand but you could also be using for instance a smaller sire in an outcross with the dam being heavy inbred and have her throwing pups that outgrow both.
well thats what i experienced at least and she really did have troubel throwing them had to get a python shot to boost her contractions. she had such a hard time with pushing out the pups she bit of a piece of her tongue, the pups where huge when they dropped. so thats what i was getting at with my post sorry if i confused ya.

 

Thanks fblb. Zuidwest, physical size difference as in any complications physically.

 

i get ya buddy, the stud could be small compared to his littermates which could mean the pups he produces could be bigger than anticipated.

 

I have seen 45lbs females/60pound male throw 35lb dogs. And seen a 40lb female to a 50lb male throw a 95lb dog.So it can always vary! Hope that helps.

 

lololol!!!!

 

I got a buddy who bred a 25lbs female to a 52 lbs male with no problems.

 

my friend took his best dog coco to his best male idr the name but coco was like 65 lbs kinda short and wide but stil quick ya know and the male was small around 35-40 and they produced a dog with long legs and an overly stocky top about 75 lbs. he was a really weird dog came out real slow so he gave him to a farm

 

I dont think i ever seen a problem with size breedins unless ur breeding a 20 pounder to a 120 pound bully u should b st8.

 

For a gyp's first breeding I would prefer to go with a stud that tends to throw dogs around the same size as the female. Maybe a bit bigger but not much.

After she's whelped that litter with no complications, I may use a larger dog.

All sorts of things happen to a female during the gestation and birthing process that "loosen things up" and make it easier for her the next time around.

Of course, not every gyp is the same and what works with one may not work for the other. It's one of the chances you take every time you breed a dog.

Complications are dangerous and expensive, and all the knowledge in the world will not help you when your female can't deliver or retains pups.

So I guess, size DOES matter LOL

 

I agree DryCreek, that was my opinion in the conversation.

breeding a 20 pounder to a 120 pound bully. lol deadgam33 I was talking bulldogs. I like em fit not fat.

 

We bred a 60 lb male to a 33lb female. She hadno complications even through she had one pup. I know of a 50 lb male that was bred to a 34 lb female and she 13 pups off one stick and no complications. Both males were from larger families. nonocomplications

 

A small bitch bred to a large male should not have complications during birth. The pups pre-birth growth is limited by the bitches womb space, litter size, and the amount of nutrition they receive from the bitch. Birth weight has little to do with adult size, and so a small bitch could whelp pups that grows to be considerably larger than her. The only limitation is if the male is too large to actually mate the small bitch, in which case AI is a viable option.

As crazy as it sounds, a small bitch bred to a large male is better off having a large number of pups in the litter. This is because in large litters each pup is smaller at birth and therefore easier to deliver. A small litter will produce bigger pups at birth that would be more difficult to deliver.
