My 3 year old, picky boy surprisingly just licks it off the dropper while my 8 year old lady won't, but luckily i can get it on her and massage it in. Since I've only been using it for a couple of days i don't know how well it works, once i have made it a daily routine for my babies, i will update my review if i see changes in their biting and itching habits!
11/16 update: my youngest loves the coat oil, he will attempt to lick inside the bottle and take the dropper from me. Its made his coat super soft and whenever i have company, they compliment how soft his coat is, its no longer stiff and it seems to have reduced his itching. Unfortunately, my old lady still won't even try it herself.
