I've been purchasing animal products for a number of years now, mainly animal pak, stak and cuts.
The sell by date has always been digitally printed on the bottom of the canister in a dotted format.
Recently I've noticed that the sell by date has now been stamped on the bottom which you can rub off. I purchased an animal pak like this and the pills looked off colour and made me feel off when I tried one of the packs. Had a similar issue with animal stak.
Are there any animal reps that can shed some light on this? Are the products with stamped sell by date genuine or is there something potentially dodgy going on?
