The male dog will begin by sniffing the females vulva. If she is receptive she will pull her tail to one side which is known as ‘flagging’. The male will then mount the female and insert his penis and begin thrusting. During this thrusting he will ejaculate. After this the dogs will form a ‘breeding tie’. The male dog will lift his hind leg over and the dogs will stand rear to rear with the penis still inserted. During this time the bulbus gland on the males penis will swell and the dogs will be locked together. Breeding ties can last anywhere between 2-30 minutes. During this time they should not be separated as this could cause damage.

An inexperienced bitch may start to get anxious at this point and it is important that she is calmed down so she doesn’t cause damage to the males. When copulation is finished the males bulbus gland will reduce in size and the dogs will separate.
