i noticed my dog doesnt enjoy eating. i got him from a shelter in NOV he ate very happily the first month or so. but now if its time to eat he just kinda walks with his head down over to the food, smells it and sits down. hell NEVER eat in the morning absolutely refuses (wasnt like that when i first got him), hell eat at noon. and not even if i put it in a plate for him, i gotta hand feed him the canned food. and usually at like 5 he ates a small amount of boiled chicken, and at night i used to feed him a full bowl of canned food, but never really wanted it. he just walks in with his head held low and sits. i usually puta piece up to his nose and he eats a peice and if he likes it hell eat more. never happy about eating. what could be wrong hes very healthy hes been to the vet for checkups.
