Since we are talking about puppies I use a two and a half gallon water bucket.I usually put two capfuls in a full bucket.The water should be changed weekly and put another two capfuls in the clean water.This is not an (etched in stone formula) but it seems to work well for me.Good luck and good hunting.
Sulmet is a Sulpher base liquid put in the water to help guard against any bacteria in the water.I use it with LA-200 down the throat to guard against kennel cough.Good luck and good hunting.
I put about half cup to 5 gallens water once a month it helps pervent coccitocies.I Give to sick pups 2cc sulmet 3cc water down the throat three days stright it works.
