Dog still not eating properly 2 weeks after op

[NewBrian]

Has anyone else experienced this? Dog has always been greedy and eaten anything. Usual diet is burns dry food. It's taking me ages to try and encourage her to eat food, even a roast and expensive tinned food haven't made a difference. She seems fine in herself and is on painkillers so shouldn't be that but I'm starting to worry now .

Can I ask what op she had?
Have you tried warming a bit of meat up? I sometimes try a meat called nature diet and warm that up for about 10 seconds in the microwave. But I would ring your vet and take her back there. They may be able to give you an appetite stimulant.
