I've tried a lot of products over the last three years. I had good results with Ekoneem last year, but it's oily which means even more bathing is required and it can't really be applied to large areas as it's so messy - and it doesn't smell very nice either.
I tried Dermacton last year also, but I really didn't have any success with that - the shampoo bar, spray or cream!
This year I tried Leucillin spray from Heathfulpets (my go to site for everything that Grace needs) and right now I'm really pleased with this!
Grace bit at her stomach and caused a lot of damage just last week - red raw skin - I used the spray several times that same day and she didn't try to bite that area again - it didn't sting on application and doesn't smell. It's a liquid, nice and cooling and can be used again and again on the same area - by the end of day one the area was already healing and she didn't end up an oily, smelly mess! Just one week later you wouldn't know how much damage she did to that one area.
