I am someone who often take my dog ( a two year old golden retriever ) to swim and I know many others who do that. Since my dog is a fairly good swimmer I was never concerned about the safety aspects of it. But recently my friend's poddle was almost drowned in the pool at their house and this got me concerned about the safety of pets in custom swimming pools. Do you guys make sure about the safety elements before taking your pet for a swim? What are the safety features that you look for in a pool?
