MATING MANAGEMENT

• When a female dog comes to heat she may be restrained till she is ready for mating which is evident from her posture.

• Take her to the dog of your choice. If possible it is better to take the female dog earlier to the dog and leave her with the dog.
• This give her ample time to get settled. Mating takes place one or two days after the discharge of blood is stopped. This may be by the 10^th to the 13^th day after the onset of the oestrous cycle, in larger breeds and earlier in smaller breeds.
• Once a decision has been made to breed, the health of the animal must be thoroughly evaluated. Written records should be kept.
• For bitches these should included information concerning previous estrus period i.e. length of proestrus, estrus and diestrus; signs of pseudo pregnancy, occurrence of any abnormal cycle; previous breeding date and the outcomes; vaginal cytology information and complete health record
• The birch is usually brought to the male for breeding. Courtship behaviour is initiated by the male dog, and the female either will respond positively or will reject the male by showing avoidance or aggression.

             

• Courtship behaviour in the male include intense sniffing of the female’s face, flank, and urogenital area; licking of the vulva; and chasing or playing behaviours.
• If the female stands for mounting, the male Will mount and clasp the flanks of the female with his forelegs.
• In the dog the os penis allows intromission to occur prior to the development of an erection.
• An erection develops immediately after intromission and is accompanied by rapid stepping movement of the males, hind legs.
• The enlargement of the bulbus glandis occurs at this time and is eventually responsible for the coital tie.
• The first portion of the do’s ejaculate contains only sperm free prostatic fluid and is ejaculated within 1 minute of intromission.
• Following the development of an erection, the male will dismount by placing both front feet to one side and lifting one hind leg over the female’s back so that they are “locked” or “tied” together tail to tail.
• The enlarged bulbus glandis of the male prevents withdrawal of the penis from the female’s vagina during the tie.
• The sperm-rich portion of the semen is ejaculated during the first 1-5 minutes of the tie.
• Internal ties normally last between 5 and 60 minutes. The female and male should be allowed to separate naturally, once the bulbus glandis has reduced in size sufficiently.
