Welcome to Justanswer! I am Dr. Altman and happy to assist you both today!First, congratulations on your new addition! I hope you have many happy years together with Rufus :)I can give you some basic guidelines for him but if this continues overnight then please consult your veterinarian first thing tomorrow. Please remove the water along with the food. If he is vomiting even water he will continue to vomit if offered which will result in dehydration and progressive lethargy 1- Keep indoors to avoid eating grass/ leaves for 6-8 hours from last vomiting episode2- Offer a small amount of water (1-2 teaspoons hourly) for a few hours after the 6-8 hours has passed3- Start Pepcid (famotidine
) 10mg 1/8 tablet every 12 hours OR prilosec (omeprazole) 20 mg 1/8 tablet 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 teaspoon 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 Rufus comfortable and what exactly the underlying cause is. 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.Tonight every 4 hours please take a small amount of karo syrup (or corn syrup, maple syrup, honey) on the tip of your finger and put it along his gums. Not enough to swallow but he will absorb it directly from his gums which maintains his sugar level and also can help with his energy. Please let me know how else I can assist you both today. I truly hope Rufus is feeling better soon! If you have more questions or if I can help in any other way, please do not hesitate to ask!
