NaClo2 en honden.

Hello Admin
Would MMS (unactivated, i.e. Naclo2) work on my doggie. This is a 12-year-old half-size 'King Charles' who has been suffering from breathing difficulties quite a bit lately. He has the manners of short epileptic fits. Probably the heart. 
Would unactivated MMS work and what amount,exactly do I take. To breathe more freely. Thanks!
