Our Pomeranian 1.7 years pet frequently has below issues once in two weeks - 1. Vomit ( toxic foam like water ) 2. And if it gets severe he ll be very low for 2 to 3 days ( like he keeps standing at same place, it won't be active as normal days ). Food habit : 7 am : rice + curd + milk 2pm : rice + curd + some vegetables ( this we started from yesterday ) 7 pm : rice + curd + milk Please suggest what needs to be done or is there any serious problem.
