those are ticks...the vet will recommend a anti-parasitic...I am not sure what is available in the US versus up here in Canada but either spot-on or advantage multi, or revolution. These products also help with heartworm and fleas and mites.
Good luck,
Dr. Cliff
What are those bugs called, does anybody know?
Sorry I meant to say he's going to take it after work to the vet, there is an evening clinic.
