I have a 11 1/2 year old German shepard mix. Sinice the beginning of fall, she started having issues walking. We were told by her doctor she has a nerve issue somewhere in her spine. Her brain can not send singles to her back leg. Within the past few months it has gotten bad enough she can't walk anymore. I developed a system in which i put a scarf under her and hold it with one hand which hold her rear end up. And she can walk and run just fine as long as i keep up with her. She does'nt seem to be in pain and seems very happy. She is still filled with energy and sometimes comes off as still being a young puppy. She is my first dog and a great one at that. I've become very sad today when i noticed she keeps licking her genital area, there seems to be a discharge of puss like substance coming out. I have not called the vets yet, As i am sure what every is wrong is going to cost money that i do not have, and considering it may be told she can't be helped. I've wanted her to hold off being put down as long as she is happy and not in pain. To which she is happy, and not in pain, and does'nt seem to be in pain due to this issue. She had a track infection a few months ago, where she had blood in her piss. They gave her anti boitics and it went away, this seems different though. Thoughts/Suggestions?
