I got this for my 5 yr old Shih-Tzu that has many allergies. I thought it would help to flush his eyes at least once a day but I've noticed that this doesn't help him much. It actually makes his eyes watery even after I clean up his face. Once I stopped flushing his eyes out they went back to normal. Maybe it is just the severity of his allergies but I am choosing not to use this on him going forward. The price is comparable to the stores.
