Caesar is having trouble

Those of you who have been around me the past few years know that Caesar goes with me everywhere he can. He and I have been glued at the hip and he has been my best friend, when many humans would not have given me a second thought. Hehas been coughing a lot the past six months. I took him to the vet this summer, who did a chest x-ray and said his enlarged heart is pushing on his trachea, which causes coughing. He warned me that the heart will continue to enlarge and he will eventually go into heart failure. I noticed tonight that not only does he cough more often, he breaths really fast at night, like he's not getting enough air!! I'm sad to say that it's time to take him back to the vet and get him on a diuretic. I was hoping to get tires on my car and get it registered (it was due in July), but I think he will have to take priority even before Christmas for my family!! Eventually, it will get worse and he will need to be put down. From what I have read on the internet, they usually don't live longer than a year or two after symptoms start. He has been with me through some really difficult times in my life, he has loved me no matter what I look like, or anything I said or did wrong. He has just loved me for me and has been my best buddy. I am glad I am getting this new job because I am going to need a little more money so I can take him in. I just want him to hang in there for another month!! I do love him.
