I found out last night that Rocky definently has Medicentric Lymphoma. My vet took some ex-rays that the previous vet didn't take and found tumors all over his body. He also did a biopsy and that confirmed Lymphoma. He has tumors on his neck,heart,lungs, abdomen,stomach, and both back legs. As of right now he doesn't seem to be in any pain, we have him on predisone. The vet said he could live anywere between 2 weeks to a year. All depends on how fast the cancer spreads, and the one on his heart is pretty big. So me and the husband discussed last night that since he his happy, eating and still playing we will not put him down until the first sigh that he is getting sick.
Thanks you everyone for your thoughts and information.

Honey, I am truly sorry hearing this news. But, if it makes a difference, I think you and your husband are making the right decision. Putting him through chemo now at this stage, would not be what I would do either. Make him as comfortable as you can, and when it appears he is going downhill or is uncomfortable, listen to your vet when it is time to put him down. I know the last thing you want for him is to be in pain, so you need to watch him closely. Play with him, spend time with him. My heart goes out to you. My thoughts are with you.

Rocky passed away yesterday. He was happy and painless up to the last minute. He started throwing up Wednesday night and Thursday morning, he also became weak and wouldn't eat Thursday. So I had to make the hardest decision of my life to put him down, I just didn't want him to suffer anymore then he had to. We borough him home and buried him in our yard next to his favorite tree, along with some of his favorite toys, something belonged to me and some hair from out kitties back...

I would have come to the same conclusion and done the same thing. The last thing we want is for our babies to be in any kind of pain. Vomiting & not eating were signs that his body functions were beginning to shut down. Poor Rocky. I am truly & deeply sorry for your loss honey.

Thank you very much Ruby for your sympathy.

A friend once commented I don't deal very well with dogs dying. I guess I don't. I was please when you first reported taking him to the vet, and then the second vet, hoping for a solution to the problem. Despite our best efforts, we still lose many dogs, and I feed sorry for you and Rocky.
