[Dailydrool] PetzLife dental question

[Cheryl Stafford]

OK so I am checking out the PetzLife product because Otter has a very 
hard time coming out of anesthesia and he needs a dental.  The natural 
ingredients are mixed with distilled water and grain alcohol.  Here's 
the question.  Is the grain alcohol safe???  I know it has to be a very 
small amount used but still.  Grain alcohol is the stuff college kids 
mix with Kool-Aid and fill the bathtub at parties.  It's also known as 
ethanol which in the industrial form can't be consumed but is used as an 
anti-septic which I am guessing is why it is used in PetzLife.  I 
believe ethanol is derived from corn so if your dog is corn sensitive 
this could be a problem couldn't it?
Is there reason to be concerned with this? 
Thanks for any info.
