My dog is 9 and has come into a heat cycle again - spotting everywhere - she is too old to be spayed I've been told. Generally what age will the heat cycle stop? She's a beagle

Thank you for contacting Petco Pet Education Center, formerly Petcoach with your question about Lottie. She will never stop her heat cycle, dogs do not go into menopause like humans do. She will be fertile for the rest of her life, and will be at risk of developing a pyometra. A pyometra is an infection of the uterus that is fatal without treatment. I'm not sure who told you she is too old to be spayed, but that's not true. There are many dogs who are spayed at nine years of age and older. Her anesthetic risk will have to be assessed by a vet, but surgery is not off the table due to her age. Plus if you leave her unspayed, she is at risk of a pyometra, which requires an emergency surgery that costs thousands. It's better to get her spayed now. I hope this helps.

Dogs can cycle at a very late age and technically they could be at risk of becoming pregnant. A pregnancy at her age would be dangerous. I do recommend to revisit the idea of spaying her. At 12 years of age, she is not too old to undergo the procedure with a veterinarian who is experienced in sedating older pets with appropriate protocols. You would need to out weight the risks versus the benefits and make an informed decision. https://www.petcoach.co/article/spaying-ovariohysterectomy-the-benefits-in-dogs/ Continuing building up trust with her around the grooming. The new behavior could be related to heat but it could also indicate fleas. I hope this helps.
