My dog!

Question
My dog woke me up at about three this morning because he kept moving
and couldn't sit still. He was having these sort of attacks because he
would jump up scratch around his and at one point he ran to his pillow
and started running and jumping around it and he was biting it and trying
to dig underneath it. He has never had his before. But, he did go to the
groomer today and got a flea bath and got a flea collar. Do this things
have side effects? I already took his off and I'm trying to see if that's going
to help.
  Please right back soon. Thank you.

Answer
sounds like he has fleas and they are biting him, they may be biting him because they are dying. I recommend purchasing some proper flea treatment from your vet clinic such as frontline plus or advantage. Because tapeworm also comes from fles he should also be wormed
