the first time they took off nitro tape in his ear they also used sedative and he's also scheduled to get his shot... Nitro became so slow in his response and can't even stand on his own... The vet told me it's the first time that it happened to them and she refused to give nitro his shot and she insisted that nitro stay in the hospital for the night since i live 30 minutes aways from the clinic and she said that's too long of a drive if something happen... when she noticed i was worried about the payment she told me not to worry about it it's all free... nitro stay in that hospital for 2 days free of charge... did they messed up that day? maybe but they made sure that whatever mess they made that they took care of it... as far as i know after sedation most vet wouldn't let you take your puppy atleast for four hours so they can observed your puppy... so if your vet was saying it's ok it's just the effect of the sedation then im assuming that your puppy was still under sedation when they release your puppy... anyway your vet should have atleast advise you to take your puppy into emergency vet if you are worried instead of saying don't worry about it... if i were you i would asked for legal advise and go from there...
