18 week beagle puppy has had loose stools for 2 days. For the first time ever he woke in the night to go out to did a very runny poo with windy sound affects and then was a little sick. I remembered reading that feeding rice and chicken may help settle an upset tummy so that is what he has had today. He seems reasonable ok not showing any signs of pain. My worry is, he is not drinking very much and I don't want him to get dehydrated. Any suggestions/help would be very much appreciated.
