Likely to be a tapeworm segment, so it'll either be diplidium caninum or mesocestoides most likely.

Get yourself to the vet, is your dog on flea treatment? It's likely he has fleas as well, so you'll want your vet to perscribe you a good flea'er and some praziquantel based wormer. Don't get a wormer off the counter at walmart, they do not work.
