No, I'm not about to take it for my IBS :) but I've got some that looks an odd colour - sort of sludgy - should it be pink or am I confusing it with something else?
If you can hang on for a month vetmedic and some of the others usually have it in offer or 3 for 2 etc at Crufts, just checked and what I got in 03-2010 has use by 09-2011 date on it. Chris
