I have used Borax in my RO water at a rate if 1/8 teaspoon per gallon and also add a pinch of grey salt. In my entire immediate family, there are 19 canines and 5 cats. All of them have been drinking this water for 21 months and we have not had any issues.
In fact, our older dogs seem to move less painfully. Hope this helps :)

Just a note on the dosage of Borax added to the drinking water. Ted has posted that the size of the dog doesn't matter because of the amount of water intake but has specified 1/8 tsp per liter for females and 1/4 tsp per liter for males. This goes for human as well.
