Welcome to Justanswer! I am Dr Altman and happy to assist you both today!
I am so sorry Dozer is not feeling well today
I can give you some basic guidelines but if he is not improving and the vomiting is not subsiding I would advise a veterinary er to ensure that he is not having any complications of the diabetes that requires being addressed
1- Keep indoors to avoid eating grass/ leaves for 6-8 hours from last vomiting episode. With him continuing to vomit I would also withhold water for 4 hours to allow the stomach to rest and hopefully prevent further episodes. Begin Karo syrup on your fingertip along his gumline every 2 hours to ensure his sugar levels do not drop with the vomiting. He doesn't need to swallow but just absorbs directly through the gumline
2- Offer a small amount of water (1-2 teaspoons hourly) for a few hours
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 Dozer comfortable and what exactly the underlying cause is.
I also would not give tonight's insulin unless he has had a few smaller meals without vomiting as a precaution. We always would prefer to have a glucose too high versus too low in this situation...
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.
Please let me know if I can be of any further assistance to you both today. I hope he is feeling better soon!
