How to remove reddish-brown tear stains in dogs. We first have to find out the cause. If it is caused by food irritation, we only need to change the food. If it is caused by blocked tear ducts, then we need to open the tear ducts, of course. Dogs are born with heavier tear stains. In this case, we need to clean eye secretions frequently.

Tip:

Dog breeds with protruding eyeballs such as Bichon Frize and Teddy tend to have heavier tear stains, so we need to clean them more when raising them.
