If you are sure that giving him hydrogen peroxide is a good idea, and you just need to get some in his system, then you can try using a syringe or a baster to squirt it in his mouth.
I don't know whats the right amt. of hydrogen peroxide to give them. but maybe not too much, like just a cap full? maybe others here know and can help you with that. try to google and see if you can find some info. on this.
Good luck! |
