S7E5 Shining a Light, Neutering in Dogs in 2026 with Dr Lise Hansen

“Do the best you can until you know better. Then when you know better, do better.”,

Maya Angelou

The jury is in, but not everyone has heard the verdict.

In this eye-opening episode, we’re joined once again by the brilliant veterinarian Dr Lise Hansen to explore the evolving science of neutering in dogs, both male and female.

What do we really know in 2026?

From mammary cancer and testicular cancer to pyometra and beyond, we dig into the latest research on health, longevity, and hormonal impact.

We also unpack the growing role of Suprelorin implants, and what they mean for the future of canine care.

Because here’s the uncomfortable truth, some of what we’ve been told for years is outdated.

In some cases, it’s irresponsible, it’s dangerous, it’s out.

Major organisations like WSAVA, BVA, and BSAVA are shifting their guidance, but the message isn’t filtering through.

Changing long-held beliefs, and the culture around routine neutering, is proving harder than the science itself.

This conversation challenges assumptions and puts evidence front and centre.

We explore how neutering decisions can affect a dog’s overall health, and take a deeper look at phantom pregnancies, female hormones, and why, apparently, the boys might have it a little easier.

See, we said it wouldn’t be just talking bollocks!

Lez and Ross have both been in the industry professionally for well over 20 years and each has been involved with dogs for over 40 years.

Whilst sensibly they have stayed away from the ‘limelight’ regarding TV offers, they have regularly been on national and local radio, spoken at national events at NDWA, CFBA, and Kennel Club / Crufts events as well as bespoke speaking engagements for the Dog Safety Education Executive (DogSEE).

Ross wrote for Dogs Monthly Magazine for over 12 years and Lez was the first lady feature writer for a national Shooting Magazine (both Sporting Gun and Sporting Shooter).

They were also 'study buddies' and were the first in the UK to achieve a Masters Degree (Professional Practice) in Canine Behaviour and Psychology in 2011.

They work well together and apart, support and work with dog rescue organisations and train professional dog trainers and behaviourists.

Different as chalk and cheese, but maybe not as different as they like to think.Intrigued? want to know more? then check out our websites...
