145 lb female presa at 14 months

Here is a recent snap of my presa girl at 14 months, she has proved to be an extreme challenge, she is highly aggressive with other dogs of both sexes especially when on the leash and will not tolerate strangers without careful introduction, this is a seriously powerful and large female, i have come to realise that there are some presas much bigger and heavier then the standard and i have seen some dogs in tenerife close to 160lb, i honestly dont know how there can be a defined standard when there are so many dog breeds in the presas recent genetic history, in the canaries they are all shapes and sizes.
Just a side note anyone who wonders about the bite force of a presa canario, i was bitten in redirection by the bitch in question when intervening when another dog attacked her, the bit was a on off bite my leg remains bruised and swollen 3 months on from the incident these dogs can exert unreal force with there jaws.
I would like to know peoples opinions on which muzzles they would use and whether they feel a herm sprenger prong collar is humane or not, i am using a choke chain at the moment but i am worrying about her damaging her neck.
The dog in question

She is gorgeous and looks very fit! Herm Sprenger prong collars are highly recommended. I agree that a prong collar works better, if used properly, than a choke collar.
