Well, Hi Jonathan,
Hope you are doing good in this hard times.
See, Dogs are very delicate towards food and exercise. Diet is really important for good health.
Sudden changes to your dog's food may result in gastrointestinal issues, so switching dog food (varieties or brands) too quickly can upset his stomach. Above all, it's important to transition to a new dog food slowly, typically over 7-10 days. Before you make the decision to change dog foods, check with your veterinarian. If you continue to see signs of stomach issues or your dog does not stop vomiting, you should bring him in as soon as you can. He may have an allergy or food intolerance, or he may have a more serious problem (foreign body in the stomach, systemic disease, etc.).
If you've recently begun the transition to a Hill's brand food, be sure to start small and gradually build up the amount until it's the only food you're only offering.
