If you like sultanas, you might want to share them with your dog, but can dogs eat sultanas? Unfortunately no, dogs cannot eat sultanas.
Sultanas Are Toxic to Dogs
I’m sure you have heard that grapes and raisins are moderately to severely toxic to dogs. Did you know, though, that sultanas are produced from the same grape as raisins, and that the only difference is the way they are dried?
Sultanas are just as dangerous for dogs as grapes and raisins. Sultanas can cause kidney damage and even death in dogs.
If you suspect that your dog has eaten sultanas, then you should contact a veterinarian immediately.
Abnormal drinking or urination, vomiting, diarrhea, lethargy, lack of appetite, halitosis and dehydration are the signs your dog might show in the case he or she has eaten sultanas.
As sultanas are just as toxic for dogs as grapes and raisins, keep in mind to never give your dog sultanas or anything containing sultanas.
