Good but Pricey
This works well, I have a small dog so she takes 1 a day for 4 days and it seems to help a lot with any stomach upsets and diarrhoea.
A box of 10 pieces will only give 2 and a half doses (4days x1piece is a dose) to a small dog so it's a bit expensive but she loves the taste of them so very easy to administer.
