Give him a good bath with a mild dog shampoo then take him to the vet.
Even if you find no fleas, if your dog has a flea allergy just 1 flea bite could cause an extreme reaction.
Do you have carpeting? Get it professionally cleaned (at the least). Maybe removed. Have the house/apartment fumigated if need be.
Talk to your vet, use preventives, there are many to pick from depending on your location and the severity of the problem.
Don’t let the dog suffer, get professional advice (not the internet).
