My daughter's dog is real sick. He's about 9 years old. We are pretty sure he's mostly Flat Coated Retriever. He just wandered into her yard half dead one day when he was a pup. I've never seen a dog who tries harder to please his master. Seriously. It's like he knows she saved his life. Anyway, she took him to the vet and he has lots of liquid in his lungs. The dr. said 80% chance it's cancer. He could die anytime from the liquid. He's on some meds to reduce the liquid and seems to be responding. He goes back on Thursday and if he still has the liquid, he's a goner. If the liquid is reduced, she may be able to spend $1000. to find out if it is cancer and how bad it is. Of course, if he is no better, she'll have to have him put down. My question, if he's a little better, what would you do? Would you spend a grand just to find out what he has and how bad it is? There's only a 20% chance he has something that is treatable. My daughter has a good job and could afford the grand. She doesn't want him to suffer and, of course, she doesn't want to just throw her money away. She loves that dog unbelievably. She's totally torn up about it. Would you have him put down or would you risk the money and possibly cause him to suffer only to have to put him down anyway? The vet said if it was his own dog, he'd probably have him put down. What would you do?
