My Mac gets terrible yeast-type infections between his toes. My vet rec'd a solution of 1 part white vinegar mixed with 1 part hydrogen peroxide and use it to wipe between the toes, top and bottom, twice a day until symptoms disappear, then use once a day until feet look normal.
Mac would lick his feet constantly and the skin between his toes would get red and infected with weepy sores.
The vinegar/peroxide solution has worked wonders and I use it whenever his feet flare up.
Never make someone a priority in your life when that someone treats you like an option.
