Now my dog is ill...

My dog (and best friend ) Odin is sick now...I can't seem to get a break lately. I took him in because I intended to clean his teeth, but his appetite has been down, which is very unusual for him. Turns out his liver values were high. What is it with my pets and their livers? I'm the one who should have a bad liver, not them...and I'd rather it was me who was sick, even though I just got over being sick, than Odin. The Dr. doesn't think it's too bad yet, but he's on meds and I've got him on IV fluids tonight, and will take him back in tomorrow. I did get him to eat some canned food this evening, though he didn't want to take his medicine(not that I blame him ). Other than the lack of appetite, he seems fine...he doesn't act like a sick pooch. Right now he's laying next to me, his IV dripping away. I'll sit in here with him for the next couple of hours 'till he gets his fluids for the night. I hope I can get him through this...I don't know what I'd do without him. I realize that a pet's time is limited, and he is 13 years old, but I'm not ready to lose him, especially right now. ..I've lost enough family and pets lately.The fact that he ate tonight and his temperature is normal makes me think he'll be OK, but I can't help but think the worst, even when I hope for the best. Raven got over her illness, I hope that Odin can beat his, too. I'm going to do everything that I can for him. He means the world to me.
