Why Spay or Neuter?
As dogs age, if they are not spayed or neutered, it is easy for them to develop urinary system diseases.
Male dogs are prone to testicular cancer or prostate diseases, while female dogs are prone to diseases such as pyometra and ovarian cysts. Therefore, it is recommended that if the owner does not want their dog to breed, they should spay or neuter them as soon as possible.
Estrus Time and Cycle Estrus, also known as heat, generally occurs once in spring (March to May) and once in autumn (September to November). Each time lasts about 1-3 weeks, with some lasting up to 4 weeks.
During estrus, female dogs may experience menstrual-like bleeding, swelling, and reddening of the vulva. Although the female dog may lick the blood, it can still cause staining everywhere. It is recommended that owners use dog diapers for their dogs.
Signs and Identification of Estrus Pre-estrus:
The female dog’s coat is shiny, the skin is red, the breasts enlarge, and she prefers the opposite sex while avoiding the same sex. Loss of appetite, poor spirits. Estrus: The female dog’s external genitalia become congested, swollen, and bleed. She becomes restless, drinks more water, urinates more frequently, and urination attracts male dogs. The bleeding gradually decreases, and the discharge becomes straw-colored. The female dog also starts to raise her tail. Post-estrus: Swelling of the female dog’s external genitalia subsides, returning to normal. A small amount of black discharge may be seen in the vagina, and the female dog becomes quieter.
Vaginal Examination Method: Estrus can be confirmed by analyzing the cell tissue of vaginal smears.
Optimal Reproductive Age ForDog
Male dogs: 24 months Female dogs: 18-24 months (the earliest heat can occur at 6 months, but the body is not mature, so canine breeding is not recommended)
Appropriate Timing For female dogs, the first day of estrus is when they start to bleed or when the discharge changes from red to straw-colored. From day 10 to 14 of estrus, when the meaty peach-like swelling turns purplish-red, is the best time for mating. To increase mating success, mating can be repeated 48 hours later.
