There's quite a few fancy parks in Barcelona but not all of them are entirely dog friendly, especially if you like to let them run free every now and then. I usually walk my pooches (and I have four!) at Parc de la Barceloneta, which has a huge fenced area specifically for letting your dogs run and play. Parc de la Ciutadella is also a good one. Sometimes we also like to go to Parc Collserola, which is a bit outside the city but great for dogs as it's basically mostly just woods with hiking trails and picnic areas. P.S: there is also a great doggy swimming pool at Resort Canino Can Jane just outside Barcelona city center if you're looking for something to do on a hot day!
