If you are breeding dogs, or simply have a dog that has not been spayed, it is important to know the procedure for when dogs mate. Between the ages of 1 and 5, males dogs are in their prime for mating, although sperm is produced from about 4 months of age. During these ages, and up to about age 10, it is vital to keep an eye on male dogs, and females in heat, and know what to do when they get stuck, or tied together.
Dog Mating Process
The initial process for canines mating involves the male mounting the female from behind. After a short time, the male will move his hind legs over the female's back so they are now bottom to bottom facing away from each other.
The dog’s penis is not erect when entering the female and instead swells inside. This is why dogs get stuck together during mating. During the period they are stuck, which can last for between 2 and 30 minutes, the dog is releasing sperm.
What to do
The most important thing to do is to keep the female calm, especially if she has never breed before. This process can be painful for the female and so she will squirm around and throw the male dog about, which is painful for the male. This needs to be avoided at all costs, so it is best to stay with the dogs and comfort the female.
Under no circumstances should you try and separate the dogs. This is a perfectly natural process and needs to be allowed to continue in the normal way. The most important thing is not to panic and to comfort the female. They will separate by themselves and the more experience the female has in breeding, the less distressed she will be.
