The process of breeding dogs can begin after the Dam starts showing signs of heat. One should wait for 2 or 3 days after the observance of Dam coming in heat and then let the selected Stud into the dam’s pen with her. The opinions on how many times one should allow the pair to “breed” varies but the owner can leave the Stud in the cage with the Dam for a day or two without posing any menace to either the dam or the stud. When the owner is sure that the Dam has been bred efficaciously, the owner can separate the Stud.
After successful breeding, one needs to keep the Dam healthy by giving it a balanced diet with sufficient vitamins and minerals to avoid any before or in pregnancy complications that may be dangerous to puppies.
The average life of a fresh dog sperm is five days to seven days usually whereas a chilled sperm lasts only 12 to 24 hours after the insertion and a frozen dog sperm lasts just 1 to 2 hours after being inserted. On the other hand, an egg can live for five days. But it is to be kept in mind that on day one the egg is not fully developed and cannot be penetrated and on day three the egg will be perfectly ripe, and marks the best day and time to impregnate. Eggs are still ripe on day four and the eggs start dying on the day five. If breeding is done keeping all this in mind, then the fertilization occurs usually after 3 days of breeding. Normally, the puppies are born 63 days from ovulation. Keep in mind that this does not mean 63 days from breeding, as the male can breed the dam some days before, and even after ovulation. When the dog’s nipples begin to turn pink and become enlarged, it is a clear sign that the bitch is pregnant and one can be sure that she is carrying pups and that the delivery time is near.
The Whelping Box
Whelping box is a big requirement before breeding dogs. When the time of whelping or say delivery is near, prepare a whelping box almost 6 inches longer than the size of the dam, keeping in mind that all the areas of the box are accessible. The best practice is to place sporadic layers of plastic sheeting and the newspapers in the bottommost of the whelping box, so that as soon as the bottom of the box becomes dirty, one can slide out a layer of paper together with a sheet of plastic that will leave a clean layer on in its place.
The owner should be aware approximately when the time for whelping or say delivering is near. Dogs mostly writhe from still born pups, breach births, and other pregnancy, delivery and birthing problems, and if one sees any complications, like slow birthing, or partial birthing, one should not shilly-shally to take the delivering Dam to the emergency vet; and one should have no time to lose in such a situation. After the delivery, keep the pups warm as well as making sure that the pups are able to nurse, keep them clean and the supply of milk is adequate. The Dam, after delivery, will clean the pups herself by licking off the afterbirth and will help the pup position him/herself for the suckling.
