Alaska Dept. of fin & feather has experimented with tasers. The unit for wildlife is more powerful than the 'human' versions. There has been a lot of interest from other state wildlife agencies. The success of the taser and the reaction of the animals depends on hair / fur and skin thickness. Recovery times are very short. Tasers work well on humans because we wear shoes. 'Grounded' animals, like humans have to be shot at very close ranges. Good luck with that. If you think that you are going to be tased by LE, prepare by wearing slip-on footwear / wear footwear with grounding means.
I have watched Seattle PD try to tase a barefoot person without success.
