Where in south florida are ya coming to? Born and raised (and still live in) in south Florida myself and my pup has been in the pool a couple of times now. I have a raft for her and she loves floating around and watching the humans do their thing. Shes swims a lil bit but soon afterwards i take her in for a bath since i feel that shes cold once she gets back on the raft all wet. but she seems to enjoy the water. she also has a blast running thru sprinklers....but hates baths.... go figure
i think it depends on the doggy really but all my dogs growing up loved going swimming (2 shih tzus, 1 GSD, 1 collie mix).
