Wishing your dog all the very best nessiesnow. Yes it does sound like that bark water was toxic. It's good you got her to the vet quickly. She is in the best place so I hope she will recover well.
Hello~Many species of cherry are poisonous, so sadly, yes, I would say the chips could be poisonous to your dog. I am glad you got her to the vet, I hope she will be OK.
