<human>: Summarize the given text in a few sentences.

A little background: I adopted Oliver from the local shelter on September 18th. He is a Shiba Inu mix. Originally, the shelter staff thought he was around two years old, but the vet thinks he may be a little older than that.

When I brought Oliver home, he had a mild upper respiratory infection and just finished his antibiotics on Sunday. He also wasn't eating much. The vet didn't seem overly concerned and suggested I try mixing his dry food with a little bit of wet food to make it more appetizing for him. After two days of that, I finally got him to eat. After that, he didn't have any trouble for the next week and ate normally. I chalked it up to the stress of a new home and being sick.

As of Sunday, he has gone back to not eating. Since he is no longer sick, I haven't been so concerned about it and figured he'd get hungry enough eventually. Today, he still hadn't touched his food and even started snubbing his treats. I sat on the floor with him and offered him a piece of food, which he took. He wouldn't eat from his bowl, but seemed delighted to eat from my hand or from the floor. As soon as I stopped, he lost interest in his food.

Obviously, I don't want to encourage my dog to only eat from my hand. I'm kind of at a loss with what to do for him. I've had dogs before, but never one that didn't love food. He doesn't appear to be losing weight and still has energy to run around and play, but I feel guilty not making an effort to get him to eat.

Should I not be so concerned and go back to the mindset that he'll eat when he gets hungry enough? Or does this sound serious enough to require veterinary intervention? My coworker suggested that maybe he was fed from the table or only fed people food previously in life, because he does beg when I'm cooking or eating dinner. I don't oblige, since I don't want him to think that is what he gets to eat.

Any advice would be much appreciated. I love this dog and want him to be happy and healthy.
<bot>: My dogs has reverted to snubbing his food and seems to only want to eat from my hand. I'd like him to become more independent and eat on his own.
