Cant say what it smells like just that it will knock your head off from 5 paces.Rosie had it 2 weeks ago, kept thinking She smelt, gave Her a bath etc but it just got worse.....so off to the vets, but I had already had a look and the skin on the fold looked a little dry but not sore and I had started wiping with very dilute Hipiscrub,( as seen suggested on here) then drying it but She still had antibiotics.I think the Hipiscrub had started to work as it cleared up quite quickly, She now smells'normal' and the vet suggested using a dilute Hipiscrub wipe a couple of times a week.
