Hi there...well I see you are in Columbia..it may be different for you..but over here in the U.K. we can't take our little ones into hardly any stores at all..even in a carrier...All shops etc. say "No Dogs" except Guide Dogs...which does make socialising pups a difficult thing...as crowded shops would be good I reckon . Markets are o.k. as are some Garden Centres..but again not that many. We wouldn't get away with it..even in a carrier.
Last year when I carried my little Sammie everywhere with me in my arms..I tried several places...to see if they would let me in with him...only a few were understanding...
So over your way..it seems a lot more doggy friendly than over here...
