No HIP certificate is what you get from your doctor that says your fake hip is good to hunt on.
I got that for my dog, does that count?
As long as he/she doesn't àsk if the hip cert makes him/her look fat.
Course, if your dog is answering you there may be a different certificate requirement
I've still got two real ones so I'm exempt from the cert requirements, though one is getting a little gimpy.
