Yesterday was such a day, and I had the little bottle on the bookcase by the sofa. Sabir sat with me all day yesterday and saw me using it.
He also sniffed my open mouth with deep thought.
Today is much better. No need for any numbing. But twice now Sabir has taken the little bottle from the bookcase, carried it into the kitchen, gently, without chewing, and put it at my feet.
Once I figured it out I praised him of course, and put it in my pocket. I will have to be careful not to leave such things around where he can get them, but what a thoughtful dog!
