Nah, My dogs like fruit and Veg. Too much acidic fruit can upset their stomachs, and guess its quite sugary.
Avoid grapes and raisins... they can lead to renal failure. Onions not good either, can get anaemic. Garlic is from onion family, so need to be careful with that too, I personally wouldnt feed it raw, but see what others have to say, I am no garlic expert.
I usually cook a little bit now and again and put it with their food, cos they like the taste.
Yes grapes and raisins are a no no ,and onions are toxic to dogs,garlic is ok .
