Make a appt with vet to rule out obstruction.I know what you are going though my little one is always into everything. It only takes a second. Peanut ate a pencil off to vet x-ray and meds.(160.00) Last week he was in the hospital for 24hours because he had a bad stomach ache. Doctors said it was from change in diet Dog Food and people food( my Husband was giving him leftovers everynight after work) which he doesnt do anymore. So please talk to your vet. Keep us posted .
