MedicationsHow to prevent dog fleas? K9 Advantix, collars, oral meds: combine?
1. You don't need to give Daisy a flea bath before giving her the Advantix. You can give her the Advantix now. I don't recommend flea baths because they don't work well and can be very irritating to the skin.
2. You do not need to use the Advantix with the Sentry flea collar. Using Sentry (which contains fipronil) and Advantix together should be done with caution, as they have not be approved by the manufacturers for use together. The Advantix alone is enough protection.
3. You can give Daisy Capster with the Advantix. It's a one time pill that stars killing fleas in 30 minutes, and is safe to use anytime. That's the only oral medication I woken recommend to use in combination with the Advantix.
Don't forget to disinfect the environment as well. Wash Daisy's bedding in hot soapy water, and vacuum the furniture and carpet surfaces. You can use a flea spray in the home such as Indorex, or you may need to flea bomb the house to kill the fleas. I hope this helps!
