We use this often. Chase and Jake have been on it for a week now. They gave us the 32 ml bottle since they are both on it. Usually, we get the smaller bottle b/c it is a one-time deal.
Again, as they have explained, it is dosed by weight and that is clearly marked on the bottle.
I think it smells like hyancinths. I frequently give it on a full tummy and with food as well; although, it says you can just squirt it on their tongue. This week Jake has decided not to eat like a farmhand, so he is getting it straight in the mouth after his supper.
