My 4 pound 8 year old chihuahua has eaten 30g of dark chocolate. We didn't know for 2 hours and have now rushed her to the vet. She has a raised heart rate and has been induced to vomit but they have had to put her on drugs to slow her heart rate. We have been sent home and they are keeping her in. I am so scared. She suffers from seizures. Has anyone else had this did their dog get better?
