Yes, at first I could tell (RIGHT after he ate the bottom half) he had a tickle in his stomach, and my mother says that frog legs are still able to move a bit after they are detached (poor puppy has flopping legs in him!!!

)
My friend works for some wild life organization and he says that in Minnesota there aren't any dangerous frogs, mainly because of the weather...I hope he's right.
It has been well over an hour and he laid in my lap like normal, and is snuggilng in his bed now. He seems to be acting normal...He is my first dog ever, and I would die if something was to make him feel bad
I'm sorry to hear about the silica packet...Good luck with everything, keep us posted.
