Of course he won't! How on earth could anyone ethically authorise the dispensing of drugs to an unknown 'patient' when it might be wholly inappropriate?
Yep that's where I got it from recently when my friends went over to Spain. Unfortuantely my friend got her dogs their usual medication etc. and somehow one of them managed to get into her suitcase and eat the whole lot, costing my friend a lot of money with two dogs in the vets on drips for nearly a week as they weren't sure whether the other dog had ate some too. Luckily it seems as though they are fine, but it ended up being an expensive price!
With overuse of antibiotics being a real problem with resistant bugs developing, I am shocked that you can just by AB's anywhere in the EU without prescription.
