Why Timing Matters forYour Dog’s Health
As a loving pet parent, you want what’s best for your dog. But when it comes to neutering, timing isn’t just a detail – it’s critical. Neutering too early can disrupt growth and development. Leaving it too late can increase certain health and behavioural risks.
With NeuterReady, you’ll know the exact time your dog is hormonally and physically ready – so you can make an informed, confident choice.
“We have a background in the veterinary industry and knew that recent research supported allowing puppies to reach hormonal maturity… Knowing that time frame allowed us to make the best decision for our puppy… We highly recommend taking this test that opens up real options based on new data”

Backed byVeterinary Experts
NeuterReady isn’t just a helpful tool – it’s grounded in rigorous veterinary science. Developed with input from leading specialists in reproductive medicine, our approach ensures that every recommendation is based on real hormonal data, not guesswork or generalised timelines.
By identifying when your dog has reached hormonal maturity, vets can tailor their advice to each individual animal – supporting healthier outcomes, smoother recoveries, and greater peace of mind for pet owners.
“As a specialist in veterinary reproduction, I strongly support InsituGen’s NeuterReady platform. For too long, neutering decisions have overlooked hormonal maturity – a key factor in long-term health. Detecting hormonal maturity before neutering allows for more personalised, informed decisions and reduces risks like behavioural issues or long-term health impacts, such as certain orthopaedic problems. At the very least, it should be part of the conversation with the owner.”
