Just noticed this on 6 year old labs leg today (outside of leg, not where he lies on it). Any ideas? (say its not mites!!!). Checked him all over and on close inspection think I can see something similar, but tiny and not noticeable unless really looking/moving hair about an inch from his eye (say its not mites!!!).
He has Bravecto once every 3 months, last time was 13 weeks ago so we are a week late.
He's due at vets early next week anyway for annual check up/vacs so will get them to have a look at then and pick up next Bravecto.
