<human>: My dog had valley fever when he was very young (we live in Tucson, AZ, very dusty) but got over it and was pretty healthy. Last September a limp turned to an unusable leg and a vet visit. They could not for the life of them figure out what was wrong with him. He was put on a ton of meds for bad hips and pain so he could live life comfortable. Eventually he started looking pretty sickly so we took him in to stay at the vet under a better watch. He got very sick and had 3-4 second seizures every few minutes.The doctors some how figured he had valley fever in his hip, it had somehow grown into the bone. Unfortunately, the valley fever combined massive amounts of meds had  done a serious job on him, and his kidneys were failing. The doctors said he had a chance to live, but there was nothing more they could do. We took him home, continued his pain killers only, and the doctor said we had to give him subcutaneous fluids (nutrients) every day because his kidney was working at like 10% (said the vet). I had never heard that word before, and learned that it just means into some part of your body, not into the blood stream.To do this put a needle into the flabby skin on the back of his neck. Because I have never done anything like this, including sewing, (19 year old college student) I had a hard time getting it in the right spot sometimes. It broke my heart to see him so debilitated. Eventually my mom and I decided that this was it for him, he wasn't happy and wasn't going to get better. The vet came over the next day to put him down.

I can't hear/read/think the word "subcutaneous" now because it reminds me so well of that horrible week.

Give me the gist of the text in a nutshell
<bot>: dog got super sick, had to insert needle into the back of his neck to give him "subcutaneous" fluids, put him down shortly after because he was not getting better
