My dog has ticks help!!?

I just found a Dog tick in my bathroom and got it with a paper, i googled pictures of dog ticks and it matched. It was only 1 that i found and it wasnt on him but my dog is always biteing his back right leg like it itches alot. Please help! Should i take him to the vet or just search for ticks on him myself? ( hes 3 months old and hes a maltese. )
