The time length that your pet is still contagious really depends on the type of pet ringworm treatment you are currently using. Your veterinary prescribed treatments for ringworm can take up to one month before your pet is no longer contagious especially if it is an oral medication.
When using the PetsBestRx ringworm treatment, your pet should no longer be contagious after 48 hours of application of the ringworm products. This usually consists of one application of the PetsBestRx Pet Wash for dogs, two applications of the PetsBestRx Sulfinex Cream, and two applications of the PetsBestRx Healing Gel or Healing and Protection Spray depending on if you are treating a cat with ringworm or a dog with ringworm. We do suggest when treating a dog that you use the PetsBestRx Pet Wash to bathe your pet. This will insure that any ringworm spores that may be on the fur are eradicated.
Sometimes there are ringworm spores on the fur without a visible ringworm sore present. For cats it is suggested to spray the PetsBestRx Healing and Protection Spray lightly all over the coat and rub in to kill ringworm spores on the fur. Please do not saturate your cat with the PetsBestRx Healing and Protection Spray.
Another way to tell if ringworm spores are present on the fur is by using a black light. Your pet’s fur will glow green if there are ringworm spores present. The PetsBestRx Pet Wash is not made for use on cats or other delicate animals. Also if your dog is under five pounds the PetsBestRx Pet Wash should be diluted half and half with water before application.
