Is there an upper limit for chlorine that's too much for dogs? We have a new puppy (12 weeks) that, for the first time for a dog of ours, we have decided to teach to swim and behave in the pool. I am currently keeping the FC around 8-10 (CYA 60-70). Certainly, when I was fighting algae last month and FC was near 20, I would say levels like that may be a problem, but is it really?

Any resource for toxicity levels for FC in pools for pets?
