Mornings with Daisy used to start with a yawn and a long stretch. Then the yawn started coming with a squint, and a thick yellowish gunk crusted in the corner of her eye before breakfast. I wiped it, she blinked, we moved on, and for months I told myself it was just sleep in her eye.

It was not sleep. Dry eye, the vet called it, or KCS if you like the long name. The immune system, for reasons nobody fully explained to me, turns on the glands that make tears and slowly shuts them down. No tears means the eye dries, and a dry eye is an angry, scratchy, infected eye. Daisy had been rubbing her face on the rug, and I had read that as itching, not pain.

The signs were there if I had known to look. Sticky discharge, the kind that strings when you wipe it. Redness along the rim. A dog who blinks more than seems normal and squints in bright light. Her third eyelid, that pale flap in the corner, kept creeping up, which our vet later said is a classic tell. I had noticed it and filed it under strange but fine.

The test was quick and a little sad. The vet put a tiny strip of paper under her lower lid to measure the tears, and it barely wet. Normal dogs soak the strip. Daisy's stayed nearly dry. That number is what changed my mind from it's-nothing to it's-real, because you cannot argue with a paper strip that stays white.

Here is the part nobody warned me about. The drops are for life. Not for a week, not until it looks better. Forever. Cyclosporine, the usual one, or a brand called Optimmune, goes in the eye twice a day to tell the immune system to leave the glands alone. Vets say most dogs do well on it, but only if you actually give it, on schedule, every single day, including the mornings you oversleep.

I missed a few mornings at the start. The eye looked fine, so I thought we were done, and within days the gunk came back thicker. Our vet was kind but firm. This is a manager, not a cure, she said. Stop the drops and the dryness returns, because the underlying attack never really stops. That is the deal with an immune problem. You keep the truce, or the war restarts.

The drops sting going in, just for a second, and Daisy learned to duck. I got good at the two-person trick, one to hold, one to aim, though most days it is just me talking nonsense while she tolerates it. A soft cloth, a steadying hand, and the routine became as normal as brushing teeth. She does not love it. She does not fight it either, which I take as a win.

What scared me was the ulcer risk. A dry eye scratches itself, and a scratch on the clear part can go bad fast. Vets say untreated KCS can cost a dog its sight, slowly and painfully, and that is the line I never want to cross. So even on holidays, even when the eye looks perfect, the drops go in. The cost of forgetting is too high to risk on a good day.

There is a thicker gel for night, and occasional lubricant during the day if the air is dry or the heater is on. Our vet said keep the environment kind, no smoky rooms, no wind in the face on car rides with the window down. Small things. They add up. Daisy's eyes now look clear most days, and the morning gunk is a faint memory, which is the whole point of the boring routine.

I still check her eyes first thing, before the kettle. Old habit. Some days one looks a touch red and I add an extra lubricant, and by evening it is fine. The vet said trust the pattern, not the panic, and she was right. We found the rhythm, Daisy and I, and the disease that I nearly waved off is now just another line in the day.

The follow-up visits matter. The vet rechecks the tear strip every so often to see if the dose is right, because too little and the eye dries, too much and it weeps. Daisy's settled at twice daily, and we stopped going every month once it was steady. If your dog has gunk that never quite goes away, ask about the tear test, because a five-minute check can save an eye.

People ask if it hurts her. I think it did, at the start, before the drops. Now she blinks like a normal dog and chases the garden hose. Painless once managed, the vet said, but only once managed, and that word only is doing a lot of work. I don't skip. I haven't skipped since the morning the gunk came back, and I don't plan to.
