I have no experience but you wold think the chlorine is so diluted he would have to drink ALOT for it to be harmful to him. When I researched it, it is said that the pool water is NOT detrimental to your dogs health but should be avoided. I think you got the right info when you googled it. If you catch him drinking the pool water just make sure he drinks his water also. But like I said I think he would have to drink ALOT for it to affect him. Just start telling him No every time he is about to drink it.....although I m sure that is hard. A pool is just Giant Drinking Bowl!
