Pet's info: Dog | Bullmastiff | Male | unneutered | 100 lbs

My dog has fleas. He’s itching really bad but he doesn’t see the doctor until Monday. Is there anything I can give him to help subside the itching? He is a bullmastiff that weighs roughly 140 lbs.

Poor Tyson! I can give you a flea treatment program for him. First, I would give him Capstar. It's a one time pill that starts killing fleas within 30 minutes. Then follow up with a spot on treatment, such as Advantage or Revolution. This is a treatment that has to be used once a month. You will also have to disinfect the environment. Wash his bedding in hot soapy water, and vacuum the furniture and carpet surfaces. You can use a spray to kill fleas in the house, such as Indorex, or a flea bomb would work well to kill the fleas in the home. You can also try giving him an oatmeal bath or a bath with a flea shampoo you get from the pet store to give him temporary relief. Best of luck.
