i am very worried about my lurcher dog billy who seems to have some sort of balance problem.he as now not eaten or drunk anything for nearly three days now.he seems to be holding his head to the left and this seems to be affecting his balance.i had him to the vets yesterday(4th oct)she give him some antibiotics(synulox),steroids and some rehydration powder,but this morning he seems worse,the vet checked his ears which she said can affect his balance but they seemed ok although his temperature was slightly high.has anybody come across this before any advice would be appreciated thanks.
