I have had good luck with Interceptor Plus for heartworm. For flea/tick I just do as necessary. I don't use oral flea/tick meds since Jackson's belly issues -- I just don't want it to be processed through his stomach just in case. So we use the topical now maybeee 3 months out of the year in the summer. He gets baths every week in the summer as well so we're always checking for ticks. |
