My pet vomits white foam in the morning after his walk. A couple of days ago, I switched his dog food because his usual one wasn't available. His bowel movements are normal. I've given him a Dompan tablet before his meal and 8ml of Digyton Plus after. Is this okay? If any vets are available, could you please review this message and suggest if this is fine?

Hello. Yes. The medicines that you have given look fine. But if it doesn't subside, I advise you to contact a veterinarian. And whenever you are changing food, try to introduce the new product in small quantities like, for the first few days give only 10% along with 90% of old food then increase gradually. Its best to get the new product well in advance before the current stock gets exhausted.
