I asked this question because I've seen the notices on some parts of the beach and perfectly understand the reason for this but........on my latest visit during the last week of August first week of September I saw quite a few dogs with both English and Spanish owners walking on the beach.
On Cabupino beach there was a large Alsatian with it's own umbrella almost everyday with a Spanish lady! On Rosario beach a little further along there seemed to be a quite a few dogs on a daily basis.
I'm hoping to take my dog with me next year for a three week holiday in June, and would love to take him on the beach either very early in the morning or later on in the day for a walk and a swim!
It's a bit like the rules of our community pool - no large inflatables in the big pool, no loud music, no lone children under 14 - all broken under the nose of a lifeguard who does NOTHING about it! One guess what would happen if I added my dog to the mix!
