I found these bugs in the morning, my dogs bed is on our bed and he has a lot more in his bed than ours. He does not have any on his body so I decided to exclude fleas. They look like pieces of lint but they move slowly and can not really see the legs. What could these be?
This is almost certainly a tick of some sort. Which tick it is, is hard to say without a close (macro) photo and knowing where in the world you are.
If you have found a number of them on bedding, it is highly likely that they have been on him for a while and finished their blood meal and are now looking for a place to either progress to a new stage in their life-cycle or to lay eggs.
Ticks are also really really good at hiding and often seek out crevices on the body (e.g. armpits, groin) and sometimes even inside noses or ears. These are pretty hard places to search and the early life-cycle stages of ticks are tiny and pale (<2 mm and skin coloured), so they can be really hard to detect.
You can get over-the-counter tick treatments from most veterinary stores.
