Before Breeding Dog Facts


A female can be breed as soon as she has her first heat, however it is highly recommended to wait until she is 2 years old so that she is old enough to be screen for genetic defects that can be passed on.  This is also important because she needs to use her energy for growing to her mature height and weight before energy is put into carrying the pups.

A male cannot be use for breeding until he is older than 6 months, before that he does not have live sperm.
Both potential dam and sire should be tested for breeding health. This includes a CERF eye test in which the dog will be cleared of any issues by a board certified member of the Canine Eye Registry Foundation.

Behavioral problems can be heredity and any dog with temperament issues should not be bred.

Unless the female was vaccinated recently, she will need booster shots to protect potential pups.

General Dog Breeding Facts

A female should be 2 years old for her first breeding and only have another pairing if she is found to be healthy afterward.

It is ethically wrong and neglectful to breed a dam every heat cycle.  The most she should be bred is every other cycle or 2 cycles in a row and then given a rest.

She should be retired by the age of 7 at the most… Earlier if there are any health issues.

If a dam needs to have a Cesarean section, it is best to not breed her again.

The best time for success is days 9 to 14 of her heat cycle.

To ensure success, a mating can be done 2 days in a row, but no more is suggested.

You cannot predict the coloring of the puppies only by looking at the parents…. Coloring DNA goes back 5 generations and in some cases even further back.

Once in a while, a puppy can be a Throwback. This means that they have the appearance of their ancestors from long ago and not the standard that is known of today. An example is a Pomeranian…if a Pom pup is a Throwback he or she will be white and large like the ancient Spitz dogs that the breed originated from and not the 5 pound dog that we know of today.

For dogs with Merle genes, breeding Merle to Merle should not be done!

It is best to not feed the female right before a tie is to be made.

The female dog may not always be receptive to the male, only if she lifts her tail to him is she accepting him.

With almost all of the different breeds, it is best to pair a smaller male with a larger female, this is for the health of the dam.

Never try to break a tie when the dogs are locked together… if the female is showing stress from being under the weight of the male, you should move his front legs to the ground to reduce pressure.

Pregnancy Dog Breeding Facts

While the average pregnancy lasts 63 days, be prepared for labor to begin any time from 59 to 65 days.

If a female does not enter labor by day 65, she should be brought to the veterinarian.

A dog can become pregnant even if you think that a tie was not made.

Never allow a female to tie with 2 different males…she can become pregnant with pups from both and the only way to match pup to sire is with DNA testing.

One of the first signs of a successful mating is that the females nipples will become enlarged and some that you never noticed before will pop out….This often happens between days 21 to 23.

The veterinarian can confirm how many puppies are expected, but not before the 6 week mark. Before this time the bones have not solidified enough to show up clearly on x-ray.

A blood test will only be accurate after day 30.

It is quite normal for the dam to want to be alone at certain times, she should be provided with a soft, comfortable area to rest that is near enough you to keep an eye on her yet also gives her privacy and a place to retreat to.

It is possible to have twins just like humans do; they will be in the same amniotic fluid sac.

Always keep the male away from the female during delivery, he should be in another room with the door closed securely, put in a secured crate, etc.
