I have the opposite problem regarding my rescue labs attitude to hypos.
She has decided it's her mission in life to eat all of my hypo treatments stashed around the house, so far she has eaten
Nougat 90gm bar minus a small section for a treated hypo.
Kendal mint cake minus 1 square
Gluten free ginger biscuits taken from a sealed container.
1 tube of liquid glucose removed from bum bag by undoing the zip with her teeth
1 bag of unopened sour sweet and they were sour as well.
I hasten to add this has been over a period of 4 months and not all in one go.
I have now resorted to shutting her in the hallway with treat toys and a bone when I leave the house now.
