I would be very careful. There are alot of 'dog trainers schools' out there that are a con job.
Research them before you take them seriously.
I can send you info (web addresses) on a couple of good schools in the US just so you can compare and see what you should be looking for. And what you shouldn't settle for...
Are the teachers at the school you found certified pro dog trainers?
And I don't mean if they've been to a couple dog trainers seminars. If they are not then they have no business opening such a school. Ask them to see their certification and check to see that they have spent at least 6 months in a dog trainer's school in another country (this is the BARE minimum you should look for in a teacher).
You can also ask to see what points they have been given in working trials (Schutzhund)although this will only show that they trained THEIR dog -or bought him ready. It says NOTHING about how they could train dogs for clients (with behavior problems for example) unless they have titled many other people's dogs in SCH or BH (obedience). If you get that far, then ask to visit a few classes and 'customers' and talk to 'graduates'.
Anything less than the above and you should prefer to go on your own with the help of a 'real' pro-dog trainer as a mentor. Not only will it cost you less but you will learn something and definetly become a better trainer.
A school such as you discribed opened last year in Greece (I hope you don't mean the same one). Nobody on the premises was certified yet they gave YOU 'certification' in only 4 weeks of lessons (and very few hours). Nobody can become a dog trainer that fast even in the hands of the BEST trainers in the world. The strange thing about these people is that they had an article in a magazine (Kynologia) announcing their school but 'forgot' to write a phone number or adress OR name their trainers. I practically had to hire a detective to find out about them. Be very careful. You could really end up paying to teach THEM a lesson or two in dog training <img src="/ubbthreads/images/graemlins/laugh.gif" alt="" /> .
An interesting book that will help you is "Top Working Dogs" by Dietmar Schellenberg. Also, Dr. Nicholas Dodman's books on behavior are very educational : "Dogs behaving badly" and the older "The Dog that Loved too Much". These are just some of my personal favorites.
I was in your shoes almost 9 years ago and have been training in your country ever since (after a whole year at a canine college in the U.S and working in a dog training school in Germany). I spent a small fortune on my certification but the 'paper' doesn't really mean much -the experience was priceless. Anyone can train dogs without any certification. And you can actually get 'certification' over the net for enough $$!
Call the president of the Greek SCH club. He will tell you directly if this school you've found is up to par. He is an excellent trainer and very helpful man. He may even agree to train you!
If you really want to be a dog trainer, be a good one -I will even help you all I can and I am actually a certified instructor! Greece is swimming with amateurs and con artists, please don't join them or give them your money.
Dogs are not our whole life, but they make our lives whole.
