Following rave reviews I got 2 tubs of this for our pooch. He had 6 tablets and we found it upset his stomach. So I have 1 unopened tub of 300 tablets best before 05/2020 and 1 opened tub that now contains 294 tablets with the same use by date. These are £39 a tub. Anyone interested at £35 for the 2 tubs I have delivered to you by courier (assuming you're not a premium delivery area as judged by DHL).
