I think the dogs must be seen individually, our Chaffie is looking "normal to thin" I don't like completely thin.
Buana, looks much heavier BUT you can feel his ribs as good as Chaffies ribs.
If I post a picture of Buana, you would say, he have to loose (some) weight. But if you feel him, he should not loose much more weight.
A picture is nice for a small opinion but you have to see them for the complete opinion.
From the first pictures, I really don't like the very thin dogs.
And I totally agree, people are so used to fat dogs!
If a dog is really too fat, nobody will speak up in the street (I can't resist telling the owners 🙂 ), but when we walked our Podenco (really not to thin) everybody had something to say…
