Topical treatment without oral anti-fungal medication is very slow in killing off Ringworm and is only really meant to reduce contamination of ringworm. It has not been shown to cure ringworm cases when used alone, which is why we almost always use it in conjunction with an oral pill. Lime sulfur bathes are recommended in a 1:16 dilution or 8 oz per gallon of water. Dips are recommended to be done every 5-7 days until a week after lesions have cleared up. All the while the pet is being treated with an oral anti-fungal such as Fluconazole, Terbinafine or Itraconazole, daily.

    Tasha should be examined and diagnosed by your vet before beginning any treatment. The most effective course of treatment is to dip twice weekly while giving Itraconazole orally for 21 days. You will need a prescription for the medication. Treat for 3-4 weeks . Dipping will be necessary until you get 2 consecutive negative fungal cultures.

    On average, lime sulfur dips are given 1-2 times per week for at least 6 weeks to see full resolution of ringworm. I'm glad to hear that Tchika is improving already, but continue following your vet's ongoing instructions or the ringworm infection is likely to continue. Lime sulfur dips should not be used inside of the ear canals, but can be used with caution on the ear flap during the dip. If you are concerned about ringworm inside of Tchika's ears, you may need to go back to your vet to discuss ear medication. I hope that all goes well!

    Hello. Yes you can. You want to make a 1:40 dilution ( 1 part dip to 40 parts water ) & dip Sonic once a week for 6 weeks. Make sure you do not get any dip in his mouth or eyes & he is not not allowed to groom until he is throughly dry. Thanks for using Petco Pet Education Center, formerly Petcoach.
