Hello I came home yesterday and found 25 of these on my bedspread they were not there that morning however my dogs are home all day playing on my bed. ...these bugs are completely round about the size of a chia seed with no visible head they barely move and also i noticed a white spot on its underside .
We live in a rural area and have not seen these bugs anywhere else in the house and only on my bedspread yesterday
we also have been outside a lot lately with the dogs doing yard work ...What are these things?

please help !!.. Thanks so much
