Microchipping thoughts for torts

Dear Baxter and Dandy,
I am a torty dad of one happy Hermanns aged 8. I am thinking of have him microchipped incase he is lost or stolen. I am concerned that this procedure my be invasive for him and cause issues in the future.
Your thoughts please.
Kindest regards
Rodney

Dear Rodney,

Thanks for your email. I'm by no means an expert on this, but at 8 years old I suspect your tort is big enough to be safely microchipped if you wish to do so. Is he larger than 10cm? I have read that this is the minimum recommended size, preferably bigger. There is no actual legal requirement to have your Hermanns chipped unless you want to breed or sell him, although as you say, some choose to chip their torts in case of loss or theft.

If in doubt you could always have a chat with your tort vet.

All the best to you and your tort,

Dandelion
