Hello Dear Doctors,, Priyanka this side. I have a 2 years pomeraninan male pet, Every 2 weeks it often vomits yellowish or whitish foam like water. Please suggest what is it about ?

Whitish foam is stomach acid and yellow color one is bile both are called acid reflex and bile reflex respectively. Your pet have digestive problems. Longterm treatment along with diet change will be recommended by vet after thorough examination and finding the cause.
