My husband was supposed to be watching her, but that’s another story. My daughter thinks my 4 month old puppy was eating some gold decorative foil while hiding under the sofa, by the time I got there whatever it is was gone. Do I need to panic? It’s not hard foil, and it can’t have been much, I got there quick. The dog is her usual cheerful self, but I suppose she would be while it’s in her stomach, it’s her intestines that won’t like it...!
Hard to say depending on the amount and size of your puppy.
If you are worried then phone the out of hours vet for advice. It's better to be over cautious than regret not doing anything (our dog had to undergo emergency surgery for a blockage so it does happen).
