Bob roswell, Georgia 12/20/2014 1:19:41 PM I buried our Golden Lab today after having her put to sleep yesterday. I will spare you the details of what we've been going through the past few days but I will implore you to take action if this is what your pet is facing. I am shocked at how aggressive this disease is!! From the "early" signs of tiredness and vomiting to the procedure yesterday...only 14 days!! All I can say to anyone who reads this is...Don't Delay. If you suspect hemangiosarcoma, or certainly if your vet tells you that's what it is, it's only a matter of a few weeks. And the life your dog will have of left without "treatment" (which is rarely effective) will be filled with excruciating pain. They may not show that they are in pain but you need to know that they are. From what I can gather, this disease is terminal, quick and painful. Your pet deserves better...euthanasia is the best solution...otherwise you're only delaying the inevitable. Sorry to be so blunt, I'm just sick to my stomach right now and happened to find this site where I could offer my experience. Cherish the time you have with your pets, and record as much of it as you can.
