Pet's info: Dog | Cavalier King Charles Spaniel | Female | unspayed | 6 years and 3 months old | 40 lbs
My dog (medium sized King Charles spaniel) ate some chocolate yesterday. She seemed fine, but threw up three times during the night. She seems fine again now, not having any diarrhoea or spasms, is she okay?

Chocolate can cause gastrointestinal upset like vomiting and diarrhea, but when larger amounts are ingested it can affect the heart, blood pressure and cause muscle tremors or even seizures. It might be a good idea to have her examined by your veterinarian so they can check her heart rate. If her heart rate is normal and it's been over 12 hours since the chocolate was ingested you're unlikely to see any other symptoms of toxicity, and there are no long lasting effects.
