Yes Yvonne ....... I've used Epi Otic for years when grooming my toy poodles and just recently used it on my Son's Labradoodle.
I did all my own bathing and clipping (had poodles for 30+ years) but I'm not sure if I'll groom my yorkie, which I'm picking up this weekend !! ...... hooooooooooooray
You just squirt a bit into the ear and then quickly massage the ears (folding the ears down onto themselves of course

) Then you can take either a soft face cloth (wash cloth) wrapped around your index finger and wipe the ears out or do as I did and use a q-tip (very carefully!!) and get any wax and dibris out of the ear.
With my poodles I always pulled the ear hair and cleaned that all up before I used the Epi Otic.
The dogs didn't mind it at all - they would shake their head a time or two after I put the Epi Otic squirt in the ear and massaged them but after that they never bothered at all.
HTHs ..........
