There should be a poison control phone number on the box....Call them & tell them what's happened.....Hartz products are notoriously dangerous chemicals even when used correctly........Ingestion could be serious.....I would also call an emergency Vet in your area and see what they say to do....They may want you to induce vomiting if it hasn't been too long...Make the call now.....Good luck & please let us know....I'll be thinking about you, Karla
Yes, let us know ... that trick sounds like a Coonhound we had for about 15 years, he'd eat anything. I don't remember him ever eating anything that was a problem, but that was mostly lucky for us.
