“Claro otic has been a great product for my dog who has a lot of allergies and yeast infections in her ears. This product gives her relief for about 1.5 to 2 months... even though it says a month. I try to get as much yeast out as possible and then administer it into both ears. It is instant relief for her and clears up quickly. I use 3 tubes in about 5 to 6 months. I usually split one tube into both ears instead of a tube for each ear. It works just as well and is more cost effective. (3 tubes vs. 12 tubes in a 6 month span)($50 vs $200 in a 6 month span) I hope this helps.”
