little man

A little note about this guy.
Farlee has been my biggest fan for 10 years. He has a no fuss, always up for it attitude. You offer him a quick belt down the local single track he will take it with a doggie smile and run his heart out. Farlee is always happy to see me come home from a ride in one piece, and greets me like he ain't seen me in months.
We returned for Canada a few weeks ago and all was good with him. We noted about 2 weeks ago a colour change in his left eye. I noted he was having trouble with his vision on his left side, but it was not slowing him down. Going with the age related dog problems of a cataract we took him to the vet. The vet informed us that he had blood in his eye. So we took him to the animal eye specialist. Farlee was diagnosed with urevitis (spontaneous bleeding, which has many causes) which should clear in a few weeks we were told and he was put on high dose steroids to help with the bleeding. We took him back yesterday for another check up only to be told that the bleeding has continued and as such the eye needs to be removed as it is likely he has a tumour in the eye. Now I guess I have a problem with this cause how do you explain to a animal, one that has unrelenting love for you that you have to pull his eye out. I know he will look strange (have to get him a parrot and a eye patch) and in time all will be good.
I am a bit of a hard arse when it comes to humans I guess cause most of the time I deal with people that don't give a fuck about the consequences of their actions, but when it is harmless animals that try to please you with there every action it upsets me greatly.
He has already adapted to loss of vision in his eye and still smashes around a oval getting every ball and Frisbee that is thrown until you give up. Right now he is looking at me with a dose of "hurry the fuck up" and a ball in his mouth wanting a trip to the local oval for a session of fetch.
Here's to dog's and their mate ship!
