This is so difficult, can someone give me an outside point of view? My dog is almost 15, she is a mastiff...so this is REALLY old for this big of a dog. I got her when she was 6 weeks old. But, despite all of my wishing and efforts, she steadily going down hill for the last few months and really badly the last week. She can't get up without assistance and can't sit or lay down without assistance (if we don't help, she just falls). She has almost no teeth so can't have her chewies any more. She is almost completely blind and deaf. And for the last couple of days she has been having these weird episodes where she is really frantic, whining, trying to get up, muscles rigid, hot, and panting. We give her valerian like the vet suggested and aspirin, but she just is getting worse and worse. I am thinking it is time to put her to sleep, am I wrong? I hate seeing her like this, as hard is it is for me to think about life without my girl.
