Re: Question about SWG
There shouldn't be any issues with your dog swallowing the pool water.
You're correct, TDS will generally be higher than salinity. For new pool water, there's probably not enough of a difference in TDS and salinity to worry about. Typically about 300 - 600 ppm TDS with new pool water.
For existing pools, it's best to test for salinity, rather than TDS. TDS will mostly be calcium, magnesium, and metals (even higher if you're using well water, copper based algaecides, or mineral purifiers).
Hope this helps,
