Without the additional information, the vomiting should subside with the removal of water. Since there is continued actively vomiting we want to minimize anything orally to stop the nausea created by the peroxide and chocolate along with reducing abdominal cramping resulting in vomiting. I know the thought is she needs to drink to maintain hydration but if she is actively vomiting even water he is becoming more dehydrated with water intake.
Please continue to monitor for symptoms of chocolate toxicity in case any of the chocolate was absorbed in the system which includes panting, pacing, increased water intake, muscle tremors, heart palpitations. If seen then please consider a veterinary er to treat the chocolate toxicity symptoms.
1- Keep indoors to avoid eating grass/ leaves for 6-8 hours from last vomiting episode
2- Offer a small amount of water (1-2 teaspoons hourly) for a few hours after the 6-8 hour period
3- Start Pepcid (famotidine) 0.25 mg/ pound every 12 hours OR prilosec (omeprazole) 0.5 mg/ pound daily for the next 3 days with the second administration of water (crushed if needed)
4-If no vomiting, offer small amount of white rice and boiled boneless or ground chicken or ground beef. For example, one tablespoon hourly for a few hours then slowly start to increase the amount while reducing the frequency. Keep on this diet for several days then wean into regular diet.
5- If vomiting continues after doing the above, I would encourage having your family veterinarian perform an examination to determine the next step to getting Lilly comfortable
Other indications your dog should be seen by a veterinary er sooner include: sticky gums that are pale, yellow, blue, purple, temperature rectally >103.5, progressive lethargy with less responsiveness to you, vomiting or diarrhea that includes blood, resting respiratory rate (breaths per minute) >60, swollen abdomen.
