Four steps, and the first can end the project rather than complicate it.

One: what does the product do, mechanically?

Kill, repel or mitigate a pest on the animal? That is pesticide territory unless the article is a new animal drug. Act on the animal systemically to treat a condition? That is animal drug territory. Clean or groom with no such claim? Neither.

Two: establish which marking the product will carry

An EPA registration number and establishment number, or an animal drug approval with conforming labeling. If the honest answer is neither, then the product cannot carry a pest or disease claim, and the claim is what has to change.

Three: check the claim against the regime, everywhere

Label, listing, website, social, and anything a salesperson writes. A claim in any of those is the claim, and it is the route by which a cleaner becomes an unregistered pesticide or an unapproved drug.

Four: then choose the container

A pump bottle for a pourable liquid, a dropper for something dosed by drop, or a spray for a wound or coat product. The two shelves here are 443 containers and 60 glass droppers, and the fitment follows the dosing.

Sterility is a separate gate

Anything for the eye, or anything described as sterile, needs a sterile container and a sterile process. Nothing on these shelves is supplied sterile, and that is a reason to stop rather than a specification to work around.

And hazard communication applies regardless

A shipped container of a hazardous chemical carries the required labeling and has a safety data sheet behind it, whatever the product is under. That obligation sits outside the pesticide and drug question.

Keep the four answers together

Mechanism, regime and marking, claim set, container and fitment. A change to the claim can move the regime, which reopens everything else, and that is the specific sequence to protect against.
