Unfortunately, I did not follow assiduously the schedule of three times a day and gave it somtimes only once. So what to do now? Hubby says just start again but I dont want to irritate his left eye with prolonged antibotic treatment meant for 7 days not 14. This seems ridiculous but I really take it hard that i could not follow his treatment and now it is back the eye infection. I failed. Three times a day is too many times to do every day.  And now he refuses to eat. Oh this stresses me out to no end. He is such trouble at the vet and we have no more money to pay for his super expensive care all the time. He always has some issue or another. hundred buck here, 200$ there...It is exasperating that his eye is not healed after some treatment. And now he does not eat.
