Dewclaws are normally removed within three days of being born. This is done then because the nail is still very mushy and can just be plucked out like a wild hair. After about 5 days when they start getting harder it requires surgery. At this point if you have them removed you will have to have stitches and it is more involved. If you keep the nails trimmed back he should not have a problem with them.

Hiccups in puppies is very common. You may notice it more when he is just waking up from sleeping. Nothing to be alarmed about.
