taking my dog to spain any advice please

Hi, my big long haired but very friendly german shepherd is coming to spain with us but I an reading conflicting things on various blog sites. He.s been to france with us and well received everywhere, as the French appear to be a nation of dog lovers, but, I hear spain can be a little different? I am led to believe he may even be classed as a potential dangerous breed? I assure you , he,s a big softy. so I have prepared to purchase muzzles, for public places, and keep him off the beach. has anyone got any advice or experience of traveling to spain with a big dog, we are going to costa brava,
