I have a new pom baby for the past 3 weeks and he is giving me hell to eat. He will not eat just about everthing I give him. He may sniff but mainy walk away. What is causing his lack óf interest in food? He is playing a lot and also too active but wont eat. What could be the casue of this. Vet said dont worry just give him B12 but I have not yet, will do so tomorrow. Why wont be eat?
