You have not mentioned which type of gum he has eaten? A chewing gum or gum containing xylitol, sugar free gum or orbit gum? It is very much necessary to take him to vet for treatment. If you have already visited then get second opinion if he is not recovering.
My Yorkie/chihuaha Mix Has A Bloated, Hard Stomach, And Keeps Shaking! Hes Still Eating And Drinking, And Having Bowel Movements. Can You Help Me?
My Yorkie is 4 years old and has a fever- I wrapped him in a wet towel and am giving him ice clips---have no car to take him to the vet. What else should I do?
Xylitol can be very deadly in dogs. I would take him back to the vet immediately. Good-Luck.
