Do Dogs Go Through Menopause?
Dogs do not experience menopause. Female dogs can go into heat and could technically become pregnant throughout life, although fertility declines and the risks rise with age.
What actually happens
- Heat cycles continue about every six to twelve months, and can become irregular
- Fertility drops but does not stop completely
- Hormone changes can lead to health issues
Health risks in older unspayed females
- Pyometra: a serious uterine infection that needs emergency care
- Mammary tumors: more common without early spaying
- Pregnancy complications in older dogs
Spaying
Spaying prevents pyometra and greatly reduces mammary cancer risk. Ask your vet about the best timing for your dog.
Signs to see a vet
Excessive thirst, discharge, loss of appetite or lethargy after a heat cycle need prompt attention.
