Puppy not eating

Question
We have a 9 month old boy Jack Russell, Yorkie cross. He has also been neutered. He weighs 4.8 kg.
He never seems to eat a lot, and i am concerned he is not healthy enough. This morning we gave him his food, puppy mix, some meaty chunks and other dry food (not crunchy or hard, sort of squidgy.) He hardly touched it, so he didn't eat any breakfast, at lunch we give him some wet food, with his left over breakfast, the wet food is puppy butchers. he doesn't eat a lot of that either. Then at tea, we give him fresh puppy mix.
I don't know why he doesn't eat it. Or if he is just simply not hungry. He is not skinny so we can see his bones, but i think he needs to be a bit chunkier.
Do you have any ideas why he is
ot eating?
i heard that puppies do not starve themselves, but i don't know if he is just not eating because he is not hungry.
He is not ill, or sick, he just never seems to want food, always interested in our food, and waits for us to give him our food but we never do because we know he will get use to it, but still he doesn't eat as much as a 9 month old puppy should.
Please suggest anything that you think may be causing a problem. Or why he doesn't want his foo, maybe he is even bored of it, or if you know any good puppy food that he might like better.
Thank you in advance.

If the dog never did eat very well, and has seen the vet since the problem existed, you may be over feeding it. A vet check still won't hurt. Many dogs will snarf down more than is good for them and look for more. Others refuse to eat more than than they need. Evaluate the dog as illustrated in this link, http://www.longliveyourdog.com/twoplus/RateYourDog.aspx You may want the vet to confirm your judgment. Adjust the dogs food and exercise as needed to reach its ideal body condition. Some German Shepherds and other breeds may refuse to eat enough to completely hid their ribs. As long as you are feeding a concentrated, meat based chow, the best thing is to accept it.

The worst thing you can do is to bribe a dog with rich foods into eating more than it needs. Instead, Put down the dish with what the dog should eat, and give it 15 minutes to eat. Then take it up. Do not give it anything to eat until its next scheduled meal. In a few days, it should be eating what it needs. Continue to check its ribs and adjust the food as needed. This is not easy. I had a Shepherd go 3 days on a few nibbles. I was a wreck, but she was fine. It is almost unknown for a healthy dog not to eat what it needs. Unfortunately, in too many cases, it is less than the package says, and less than the owner thinks the dog should have. Many dogs are quite good at holding out for tastier chow. Like kids, sometimes it calls for tough love.

Just stick to the Butchers.
