Poor dog, looks almost uncomfortable at that size. Humans and their breeding of dogs for specific traits produces some really atrocious phenotypic responses in dogs. Pugs for example, breathing issues, disgusting ear issues, etc. all so people can think they look cute. Undesirable traits for the dog are traits that some times humans find appealing, so while it makes ur dogs suffer, you can say "my dog is the cutest thing! Look how he sniffles and makes wheezing sounds cuz his face is so wrinkled up! Aaawww, selfie with the dog time!!!"
