Breeding - Tie
Boys can start to have sperm at 7 months old, but 10 months, is more common. Young dogs do not have quality sperm. Almost all dogs will have sperm by one year.
Stud dogs are at their prime between 18 months and 4 years old (or 5), after that, the quality of the sperm starts to lessen, and the ability to penetrate eggs, lessens. By 10 years old, most stud dogs do not produce sperm that will impregnate a bitch.
A Tie is a natural phenomenon of dog breeding in which the bulbus glandis of the male's penis swells inside the bitch's vagina. The dogs are virtually locked together for 15-20 minutes (2 to 30 minutes is also normal), during which time ejaculation has taken place. The sperm was released at the beginning of the tie, during the happy feet dance (see below) . During the tie, he is releasing prostatic fluid.
As soon as the dogs lock the male usually moves his leg over her back, turns butt to butt and they remain locked. Tied.
Tie Close Up
Getting stuck together is normal. Do NOT ice them to get them apart. The male is Supposed to swell up and get stuck inside the female for 2 to 30 minutes. At this time if you feel the Sire and Dam in this area you will feel pulsating. When you hear someone say they got a 13 minute tie, this means they were locked together for 13 minutes.

Most Dogs stand for a tie and it is important that you do not let the dam roll around or get to frisky and hurt the male, but this particular Dam insists on lying on her back.
Unless you KNOW what your pair will do when they are locked, I highly suggest 100% supervision when mating. I only do Supervised Ties.... 100% supervision.... As Accidents can happen.
After the tie they are separated with their great disapproval for at least 24 hours to allow his sperm to build back up.
With a younger male (under 4 years) 20 hours is enough, but with an older male, you may want to increase this time to 30-36 hours.
It is wise to check with your Vet. He can draw a sample from the male and check how fertile he is or if he is Sterile.
If his sperm level is Low, then you must be a little more involved in Breed scheduling.

Frequently Asked Question
Can a dam who has mated with more than one stud during a single heat, have pups from both fathers. Yes, when a dam mates with more than one stud, both of the studs can impregnate the female at the same time. Pups from a single litter can have different fathers, as the sperm from both fathers, will swim around, waiting for the eggs to ripen. The sperm from both fathers, will live in the dam for 5 days.
