Granny, what a sad story! I had one die of bone cancer. She went really fast too, just started limping and in 9 days we had to put her to sleep. Very sad, dogs seem to get cancer pretty often.
Its amazing how being blind she had adjusted..She knows the house by memory and I can no longer rearrange furniture and if something (like my purse on the floor) she bumps into it...What is funny is sometimes she ends up in the middle of the living room and comes to a dead stop...she doesn't know which way to go...She has learned to walk just barely touching the wall. Has no trouble finding her food and water bowl. But she could use a nose bumper for those times she gets a little confused...
She went blind within a week from a disease called SARDs. Its rare and there is no cure. My vet brought in an eye specialist vet to look at her, I am sure he also wanted to learn about it cause according to my research, last year there was only 4000 cases in the US. When she goes down the 2 steps to be let out she figured out a way to do the steps without falling...I watched her and she puts her paws at the very edge of the step without her nails not touching the cement step, then she knows its safe to step down...She has misjudged only a couple of times and fell down the steps...I cannot believe how smart she is....
