Thank you everyone for your support. The tumor is on his tmj in his jaw and is effecting his nerves. He has started twitching but the vet doesn't think he is in pain and he only does it when falling asleep initially but it's hard to watch. I take him out to the park and on short walks to play ball. Today he played for almost two hours, I have noticed a change in his bark and this morning he did not want to eat his dogfood, even with canned gravy dogfood and special homemade food. He did eat hot dogs and steak but this afternooon he doesn't want to eat anything, even treats. We are going to the vet to see if he can help. Kenshin acts pretty normal otherwise but not eating has me very concerned. I am trying really hard to be there for him and not to let him know anything is wrong but things are getting bad quickly. I won't hold out if it is time, I don't want him to suffer and I love him more than anything. I don't know how I will function once everything is finished. He is my best friend and the best thing that's ever happened to me and it's killing me to see him like this. I give him kisses and snuggles as much as I can and am spoiling him as much as he can be. Hopefully he starts eating, if not we might have to call it this weekend.
Every day will be his best day until it's time to say goodbye
