This is a possible and ''expected '' side effects. If signs do not resolve in the next 24 hours, a check up would be required to determine the underlying cause and treat appropriately. I would recommend to start feeding with a bland diet based on boiled chicken and rice in small portion every 6 hours for the following 48hours.
