dog wont eat after booster

my dog had his booster on wednesday and ever since he has gone off his food, normally his food doesnt touch the sides

Vaccinations can do that sometimes. How is he in himself? Is he still lively & drinking ok? If so, then try & tempt him with a little chicken added to his food, or a raw egg - something like that & see if that helps.

If he's still not eating by tomorrow I'd give the vet a quick ring.

Which vaccinations did he have? The whole lot or just the Lepto?

hi it was just his yearly booster, i asked the vet and they said that it wouldnt cause him to go off his food, it just seems weird that he eat his food in the morning and now he will only eat it if i add sunflower oil
