Hello, my name is***** and I will help you. I see that Dr Scott was asking for her weight. That was to determine if the dose of Percocet was a problem. Also to see if you should induce vomiting.
Percocet has both oxycodone and acetaminophen in it.
Since oxycodone is not readily available in dog tissues, it is not used as a pain killer.
There is no accurate data on dosages because it is not used.
As to the acetaminophen, 325 mg would be a normal dose for a 60 to 80 pound dog.
So the Percocet probably wouldn't have caused problems, except drowsiness, unless she ate more than one. Then we would induce vomiting as long as it was no more than 2 hours since she ingested it.
Let me give you the dose for 3% Hydrogen Peroxide.
For dogs over 45 pounds give 3 tablespoon mixed in a small amount of food.
She should vomit in 10 to 20 minutes. If she doesn't, you can re-dose her one more time. The sooner after she eats a potential toxin, the better.
It's a good idea to have a bottle of 3% Hydrogen Peroxide in your medicine cabinet with her dose marked on it just in case this situation comes up again.
I hope that I have given you some useful information.
