I Own A 3 Year Old Female Huskey Malemute Mix.

i own a 3 year old female huskey malemute mix. approx 3 weeks ago i noticed her blue eyes were now a dark brown colour and took her to out vet. after a physical exam she was given eye drops for both eyes to be take 4 to six times a day. on her return home it was apparent that there was some sight in her left eye but very little in her right eye. one week later we returned to our vets clinic with our dog and she was prescribed a two week supply of eye drops and pill medication that was meant to cure the infection. to date, she has received her meds on a regular basis and i will attend wirh her next tuesday morning for a prognosis . to date i have not observed any improvement . she walks with me while on a ten foot leash and any object on her right will connect with her head. the left has some sight but unless the squeaky is on her left and close to her its nor seen. she has become lethargic and sleeps a lot. trying to consult with dog specialist has been next to impossible in my area even by telephone or websites...xmas and new year . i have a good rapport. with my vets. should she be showing signs that the meds are curring the inflammation? is time becoming a factor/ her name is shilo. my name is willy
