I've been reading through old postings on this topic, but I still don't feel like I know what's going on. I have a 12 year old lab who has not been eating normally for about a week now. At first he would sniff his dry kibble and walk away. This lasted for a day or two, so I changed his food. Same thing. I bought some canned food (same brand) and that renewed some interest for a day or two again, at which time I started mixing it in with his kibble to get him back to his "normal" routine. Now we are back to the beginning, and he won't eat anything now, not even what I've already tried. It's been 2 meals now, and not so much as a lick. He is normally about 65lbs, small for a lab, but very healthy. I've looked at all your charts, and he is in the perfect range for size. I feed him twice a day, about 1 1/2- 1 3/4 cups per meal. He is drinking water fine. I've also tried mixing kibble with water, didn't help. This morning I woke up to him throwing up bile (since he had nothing in him to bring up) Should I bring him to the vet? He is old, and I'm hoping it's not a sign of the end! Should I wait another couple of meals? Any advice would help.

Hi, derringer,
Welcome to this site, and thank you for posting a question here.
I would take him to the Vet. I don't think he is that old yet, to be worried about "being the end". My own housedog is 12 yrs old, still running around, eating, playing, like she is only 8 or 9!
I would have him checked out. Being cautious is the best. I do wish you the best.

I am sure in my old posts, you saw I caution acting very soon after a dog refuses to eat. It has been long enough it is time to go to the vet. 12 years is getting old for a Lab, but maybe not the end. Last fall, my 12 year old Lab skipped eating one morning. I took her to the vet and he prescriberd some antibiotics, and she was her old self in a day or 2. My friends still have her 14 year old mother. The mother isn't real active, but maybe around a few more years.

I am glad you took time to look back. There are anumber of reason for a dog not eating. Different cases call for different responses.
