Could my dog have lyme disease with only a few symptoms?

I am currently waiting for the vet to call with their finding regarding my dog's ailment. she has a bite that red around it the size of a nickel. she does not seem lethargic and she eats as normal, but she is having trouble walking and is in pain in certain positions. a few weeks ago i was diagnosed with lyme disease and, oddly enough, these were my exact sypmtoms. i barely had a fever, i had no rash, no nausea, but i could hardly walk and i was lethargic. (apparently most people with lyme have a high fever and many much exaggerated flu symptoms) is it possible for a dog to have lyme disease and only present two symptoms: joint pain and rash? Has anyone ever experienced this?
