Do dogs smile in the human sense or is that just the shape

They totally smile. There is a fair amount of "it's just how their head is shaped" but there are dog smiles too.

Forever ago my sister moved back in with the parents and had a dog. I went over early one day to visit. Sister kicked the dog out of her room to sleep in. The dog comes sleepy waddling up the stairs on her way outside and saw me sitting in the living room. Once she recognised me she straight up smiled. The corners of her mouth scrunched up in the biggest smile ever and started wagging and came over for pets. It was the cutest fucking thing ever.

Still, not all dogs smile with their mouths closed. Google "dog laughing". It's that pant/chuff noise they do when playing. If they are doing that, look at their face. Five bucks says their cheeks are more scrunched up than they are when they are just panting because it's hot.

It's both. You can tell from this pic. This dog has clearly just spotted the neighbor's 3-year old in the back yard and is about to strike.

my dog will do that, but if he's really excited he curls his front lip and shows his teeth, but then he can't breathe and starts sneezing
