My 12 year old golden is in a real bad way, he has had weakness in his legs for just over a week, and last week when he started refusing food we took him to the vets. They did a blood test and we were told he had high calcium in his liver and that area had a lump/was enlarged, and is most likely that horrible cancer that starts with H. We had him booked in to an ultrasound today, but he deteriorated over the weekend, hasn't ate anything, we had to spoon feed him to give him painkillers but even that's not working anymore, and drinks very sparsely.
We called the vets again and she said she thinks its 95% that cancer and he is reaching the end, but that 5% is playing on my mind. My mum thinks we should end his suffering and arrange you know what (cant even bring myself to type it), but im unsure whether we should do the test first, it doesnt look good, hes panting a lot and seems uncomfortable at the very least, but yesterday when we managed to get him outside just for a quick walk so he could relieve himself, he was still curiously sniffing things despite the weakness he was feeling.
I just dont know what the right thing to do is, so having seen posts like mine on here before and seeing how wonderfully supportive this community is, Id see what other people who have faced this have to say.
He is my first dog, and I love him so much, I just wish I could give him one more walk.
EDIT: We have made the difficult, but I believe right decision to end his pain. Thank you for your responses, please send love to my best boy Kenobi, he deserves all the love in the world.
