 Don't worry about his eating.  In a new environement, that is normal.  Give him time to find his feet.  If you have changed his food abruptly, that will also put him off.  My advice is to keep him on what the breeder fed him for about a week and then gradually switch him to your food.  IME this helps to settle a pup in and means less chance of tummy troubles.

Don't try to tempt him to eat with tasty additions to his food; you will make a rod for your own back.  Put it down, leave it there for 15 minutes, pick it up again.  No healthy dog will starve himself and he should start to eat well at mealtimes after a few days at the most.

Has he had that vet check yet?  When was he last wormed?

What's his background?

Have you tried some kibble in your hand?  Have you tried putting it just on the floor (some dogs are actually afraid of dishes - I've had 2-3 fosters like that). 

Have you tried some kind of soft food?

 Good thought Callie - I have a dog like that, but in his case it is only when wearing a collar and tag... he doesn't like the clinking nose against the dish!

This is a very new puppy, so my first assumption was, the pup just needs time to settle in.

Dogs, like most other animals, won't eat or play if they don't feel "safe".  An unfamiliar environment is, by its very nature... unsafe.  It could just be this that has stopped his appetite; if so and he is physically healthy his appetite will pick up as he settles into the home and his suroundings become more familiar to him.

Chuffy and I were posting at the same time *grin* -- yeah, if it's a puppy he's probably just feeling new and you don't want a) anything too rich, or b) to start something he'll come to expect.

Tink didn't want to eat at first with me either -- but got over that right quick.  She also didn't want to drink water so I was adding water to her food, and she decided right quick it was worth eating.

Aesop didn't eat well the first few days..there were just too many things to see. And at that point I was feeding what the breeder sent with me.  He ended up eating fine, even with me transitioning him over to a new food. 

are you crating when offering food? Is he being crated at all? If he's to be shown being in a crate will be part of his life so do start now. Feed him in a crate...it will tune out distractions and help him focus on his food. Puppies IMO need a place for downtime anyways.

 I am crating him. I put the food in the crate with him but he didnt want it. I was just making sure that it is normal for this kind of behavior. All the strays I have had lately made me forget what it's like to bring a puppy in on purpose.

The breeder was feeding Purina One. I will be switching him to Purina Proplan Selects puppy kind. 

 He was last wormed at 10 weeks. I am taking him to the vet Tuesday for a checkup and whatever shots he needs.

Be sure none of the other dogs are in the area while he eats. Some pups will not eat in the presence of an older or mor dominant dog or in some cases...human. I think he'll settle down some...and honestly missing a few meals wouldn't be bad...he could slim down and be fine I think. Young joints and all that....

 I gave him a frozen neck bone to chew on tonight.Gotta get him a kong tomorrow. He isnt liking the crate at all. He did eat a little bit of food. I had to switch bowls. He prefered the metal one over the plastic bowl. Figured it out when he tried to eat Kujo's food.

I dont let the other dogs eat around each other period. Lillie is food aggresive which I dont get given her pickyness. Cheyanne is a hog and has to be fed far away from all the animals.

Right now he is howling away. He peed before I put him up. He has a nice frozen neck bone to chew on and his little Eeyore stuffy. Gonna be a long night!!!

be aware that chewing stimulates defacation so...the howling might be telling you something LOL.

I was really pleased that Aesop's breeder had acclimated the pups to crates. They weren't kept crated for long periods, but knew to settle in them for at least a short time.  Most of the litter were show prospects, so the pups are started early.

I try to not focus on eating the first several days. Unless they are acting sickly, of course. Changes are confusing to wee pups

He didnt touch the neck bone. I took him out before I went to bed though. And I got up 2 times and he peed both times for me.

Lillie was crated trained when I got her. So easy with her!! 

He cried a lot but we'll get through this. He so thinks he's a lap dog.  

 Put the crate in your room, preferably at eye level so he can see you.  His howling isnt naughtyness.... he is bewildered and possibly very frightened.  Your presence will reassure him.  You can move the crate away gradually after he is settled in and no longer needs trips outside to toilet at night.

If putting him in your room is impossible (in one house i lived the bedroom was TINY and no room for a crate), then wear an old shirt for a day and give it to him at night.  You could try leaving a radio on very softly... even a nightlight is helpful for some puppies!
