Cubby's eye removal surgery

Hi My name is Diana and after 2 vet visits and 1 very expensive eye specialist have been told that the only solution for my 12 yr old shih-tzu/Pomeranian's eye problem is having his left eye removed because he has a tumor behind it. I unfortunately can't gather the funds fast enough because as I'm sure everyone knows life happens, especially when things seems to be already rough. He still acts like a puppy rather than an old dog and its hard to see him suffering with the pain. I don't have kids so Cubby is my everything. He has drops and pills but they are no longer controlling the symptoms. Any amount is appreciated to help us meet our goal of $4000. He has had this for 2 months now due to the long eye specialist appt wait so we are trying our best to have it done for him soon before it gets worse. Thank you for reading this and for your consideration during our time of need. A Very Grateful Dog Mom - Diana
