Great question! Your adult dog should be protected, but the house will be infested and he can get the fleas when the flea treatment wears off. I can give you a flea treatment for Brody, since he is almost 8 weeks of age. 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. I hope this helps!

If it's been at least two weeks, you can reapply it. 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.

Because they have been washed, you can put them back into the cage now. I would also disinfect the environment. 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.
