PROLONGED HEAT CYCLE (ESTRUS > 3 WEEKS)
WHAT THIS SYMPTOM USUALLY MEANS
Extended heat cycles may signal ovarian cysts, hormonal imbalance, or ovarian remnant syndrome after spay surgery.
MOST COMMON CAUSES
MILD
• Variability in natural cycle (dogs only)
• Breed-specific longer cycles
MEDICAL
• Ovarian cysts
• Ovarian remnant syndrome
• Endocrine imbalance
• Uterine disease
EMERGENCY
• Heavy bleeding
• Lethargy + fever
RED FLAGS
• Cycle lasting >21 days
• Strong odor
• Blood clots
• Swollen vulva not returning to normal
• If unsure, treat it as urgent.
AT-HOME CARE

• Rule out ovarian remnant
MOST LIKELY DIAGNOSES
• Ovarian remnant
• Ovarian cysts
• Hormonal dysregulation
WHEN TO SCHEDULE
• Within 72 hrs: cycle persists beyond 21 days
• Today: heavy bleeding or lethargy
