Hello Stephanie Kyles
While that is not a toxic dose for your little boy that is definately a high dose.
If it were my dog, I would give him 1 cup of hydrogen peroxide every 15 minutes until he vomits the pill up or you feel his stomach is empty.
Then you will not have to worry about having to go to the emergency clinic later because his respiratory rate seems too slow or he is too lethargic.
I always get 1/2 the peroxide everywhere too. For future reference don't get more than 1/2 a cup in the dog total.
That's a bummer that he did not even eat the pill!
Now try giving him a piece of bread to soak up the peroxide.
You can give him 1 tsp pepto . If he vomits that up try more pepto in 2 hours.
He will be nauseous for about 2-3 hours.
Don't worry about a bonus.
I knew we were under a time constraint.
Watch out for Pepto flying every where too.
