Yes, for dogs needing low-calorie options or those with weight issues. Cucumbers offer crunch and flavor with a fraction of the calories of most store-bought treats.
Note: Cucumbers lack the protein and other nutrients found in some treatsâalways aim for variety.

Are pickled cucumbers or cucumber salads safe for dogs?

No. Pickled or processed cucumbers often contain salt, vinegar, garlic, onions, and spicesâall potentially harmful to dogs. Only feed raw, plain cucumber.

If choking occurs, attempt to gently remove the piece if visible. For breathing difficulties, call your vet urgently. Always slice cucumbers small to minimize this risk.

Are cucumbers safe for puppies?
