I am in Sarasota right now & my 2 have been to the Farmer's Market which is downtown on Saturdays - dogs everywhere & at least 2 pet stores in the area. Lots of outside dining with doggies all about.
They have swam in the Bay and we will go tomorrow to a doggie beach in Venice.
Also, in Sarasota we have been shopping in St. Armand's Circle -- every store has let us in with the dogs & fussed over them

-- also lots of outdoor dining.
We are going to go on a boat tour & I will be checking to see if the furbabies can come. Also, there is a park we are going to go to - not sure what my mom said the name is.
