3 x 225 gram tubes would be plenty initially. Administer immediately if soft stool is detected. Use if your dog has eaten sticks or dirt or if you need to remove minor toxins, Entersogel is very effective. Mix one tablespoon with a little bit of water and administer orally 1 hour before and/or 1 hour after each meal through a syringe without a needle. Also helps with browning fur under the eyes / head / paws. This is our first go-to item whenever a dog of any age has loose stool. Highly effective and must-have for any household with pets. Enterosgel is extremely safe and you cannot overdose on it. The contents are not absorbed through the intestinal tract and just pass through the system collecting the toxins within.
