I use the Purple Ear Solution monthly to maintain Max's and Jake's ears, both have suffered from ear infections and this monthly maintenance has helped keep their canals healthy!! Max always runs off to the nearest rug and rubs his ears on it as if to get rid of the fluid. So...last night we did our monthly ear maintenance, of course Max ran to the nearest rug and did his thing. Well tonight Jake got a second dose since I noticed the beginnings of what would probably turn into an infection. Max DID NOT get this second dose but I did let him smell the dropper....wouldn't ya know it...he ran off to the nearest rug to do his wipey dance anyway!! So funny!!
