I live in Texas and I would recommend the shot. Texas has mosquito's and in some places lots of em; which is how the heart worm is transmitted.

I had a dog about 20 years ago die of heart worms and it is not a nice thing. He had it twice, the first time he had surgery which is horrendously hard on them and I guess it was not quite successful. Even after having him on the heart worm meds he got it again. It is better to be safe than sorry. All of my dogs from that point on have been on heart worm meds.
