He's not a fluffy as a lot of puppies, but there is quite a bit of variability. He is definitely NOT a short hair, or he wouldn't have that fluffy facial hair. It's really impossible to evaluate his structure, even a LITTLE from this angle and in this photo. The person taking the photo used a wide angle lens, probably a cell phone, and very close, which makes his head look HUGELY out of proportion to his body. But I can't believe he looks like that in real life... It's the camera angle. Also, he's nervous about being at the vet and being up on the table, away from his siblings. (and having a camera stuck in his face) As a result, he's got his ears plastered to his head, making him look ear-less... which I'm SURE he's not!
If you want to have even a clue about his over-all structure, he has to be sideways to the camera, and standing. You can also get a better idea of structure with "soaped" pictures, but you need someone who really knows what they are doing to take good soaps... It's NOT easy, and many breeders don't bother. (though I won't buy a dog WITHOUT soaps)
That all said, a puppy can definitely have a lighter coat as a puppy, and still have a beautiful coat as an adult. here are photos of my Kodi, the day I brought him home at 11 weeks, and as an adult. He looked significantly different from many of the very "fluffy puppies" on the forum. (he also had HUGE ears for his size, but he grew into them!
) But he has a gorgeous adult coat, and much easier to maintain than many of the dogs with really dense undercoats.
