It must have fallen out of next door's rubbish. Thought it was a leaf at first but could smell it was camomile. Pup dropped a tiny bit which confirms it was a used teabag but she managed to swallow the rest before I could get it off her.
Had a quick google but couldn't get conclusive advice, what do all you experienced dog owners think? She is a 6 month old cocker spaniel.
Should I just phone the vet?
