My puppy is 7 weeks old and on puppy cerelac 6 meals a day one scoop each time along with immunity and digestive medications however she was lethargic yesterday and also skipped one meal after which she was restless for 30 mins before she dozed offand today she ate very littlein her first meal, and her deworming is about to start today, is it a cause for concern? As a first time owner i am a little concerened about not understanding the behaviours and changes in the puppy
