Yes, eye solutions are fine. When I had dogs in the past with dry eye I used human eye drops for my dogs eyes. Much cheaper than purchasing high priced eye solutions at the Vet clinic.
Or you can make your own Astringent Eyewash
Use a clena dropper bottle, combine the following:
1/2 tsp cooled clear raspberry leaf or nettle tea
1/2 tsp of Oregon grape or goldenseal tea
add 1 oz of sterile saline (available in the eye care section of supermarkets and pharmacies_
Shake the mixture thoroughly, it should be tinted yellow.
Make sure the tea is absolutely free of particles
thoroughly rinse the eye laterally from the nose outward, toward the dogs check. The idea is to wash any irritating particles away from teh animals eye. You can repeat this process 2-3 times daily until the irritating particle is removed.
