I have a dog , he looks very nice . My all family members are very worry because he is not taken proper food before 1 week. so plz give me a suggestion.
That's too sad!
But this happens sometimes. I think your dog might be suffering from mild fever or cold. Sometimes if the stomach gets infected by worms also, the hunger of dogs decreases. But without seeing the symptoms and doing the tests, it's very difficult to answer what's the exact problem. Just take him to the vet and after completing the medication he'll be alright.
