Welcome (with a sinister witches laugh) to a controversial discussion that divides even the veterinary world. Brexit, my friends, is nothing compared to this! Within an hour of my bosses sending this possible blog topic to my inbox, two features had arrived on my social media feeds from different veterinary groups. One showed commercial pet Halloween costumes being deliberately set on fire. Some didn't burn but others did; one in particular was dripping hot plastic. The take home message was that purpose-sold dog costumes are unregulated and many can prove dangerous. The other piece was from a local vets, launching a social media Halloween fancy dress competition. So. What’s an owner to do?
