"Supposed" meaning only that they should,and not that they neccessarily do....
Its only too easy to cheat,and not a problem to get drugs on the internet either-which of course,are not recorded by the vet-ie,he has no record of you ever having those drugs....
and its true expensive need not mean better.While a student at university ,one of my sons worked in a food processing plant.where they made,amongst other things,sausages.
(^He said" you would never eat sausages again,if you saw what went into them! ugh^)
"And" he siad they used exactly the same batch of sausage meat for joe bloggs cheapie sausages,as for a well known "better" supermarkets own brand!
He thought it quite a laugh that someone "swankie" thought they would be getting a better product,just because they paid a lot more!
