Flying with dogs

Hi, we recently got a plane and cannot find a harness to fit with the aircraft seat harness for our dog. Does anyone know a website with products for dogs in small planes?

At present Benji sits on my lap for take off and landing – and pretty much in between since he obviously thinks it’s comfy, but I really want him secured in the back seat (for his own safety as well as my comfort!). Our car harness doesn’t fit.

Thanks Mikel, I will check it out!
