GNC pet - puppy overdose help!

[tldtx]

Yesterday I bought the GNC skin and essentials for my golden doodle puppy (approximate 38 lbs.). There are 60 in the package, I gave 2 yesterday between her and my other dog. 56 left..had about 9 left of the calming ones I bought for the other dog. Came home after a couple of hours gone today and both packages had been chewed open and all the treats gone. Not sure if both dogs ate them (which is still WAY too many for them) or if just the puppy did. Either way I gave both of them hydrogen pyroxide. Puppy still hasn't thrown up, older dog has. 
I tried to call my vet, they said call the distributor..GNC says they don't know what to do so call the pet poison hotline. They charge $65 for advice so I'm coming here first.

Any ideas/advice on what I can do?

The vitamin D in (at least the first one) is a concern. Call your vet back and tell them that one or both of your dogs ingested vitamin D supplements.

Keep your (golden/poodle mix) puppy in crate when you aren't able to supervise her. If you can't trust your older dog, s/he should be in one, too.

(ETA) It doesn't look like there is much Vit D in those, make sure you tell the vet- probably not a poison.
