A dog's gestation period lasts an average of 57 to 63 days (approximately 2 months), though this can vary slightly. Symptoms include changes in appetite, mammary gland enlargement and darkening, and increased activity or nesting behavior towards the end of pregnancy. Veterinary checkups, ultrasounds, and a special diet are recommended.

Key aspects of canine gestation:
Duration: The normal range is 58 to 68 days, with 63 days being the most common average.

Phases: It is divided into three stages of approximately three weeks each.

Diagnosis:
Palpation: From 25-30 days old, a veterinarian can feel the puppies.

Ultrasound: It is possible from 20-25 days to confirm the pregnancy.

X-ray: Useful after day 45-50 for accurately counting puppies.

Symptoms: Breast enlargement, swollen abdomen, behavioral changes (more affectionate or apathetic) and decreased appetite at the end.

Females:
Heat in female dogs is the fertile period, lasting between 2 and 4 weeks (average 3), generally every 6 months. It manifests with bleeding, swelling of the vulva, and behavioral changes (loss of appetite, excessive affection, or aggression). The first heat usually occurs between 6 and 12 months of age.
Stages of heat in female dogs:
Proestrus (7-10 days): The vulva swells and there is bleeding, attracting males but not accepting mounting.
Estrus (5-10 days): Fertile phase. The bitch accepts the male and ovulation occurs.
Diestrus (60-90 days): The body returns to normal or begins gestation.
Anestrus: Period of sexual inactivity between heat cycles.

Males:
Male dogs do not have a defined heat cycle, but they may show excitement, aggression, excessive urine marking, and escape attempts when they detect a female in heat in the area.
