The full picture
Pickles (gherkins, pickled onions, pickled eggs, branston pickle) are all essentially brined foods loaded with salt and vinegar. The sodium content alone is more than a small dog should have in a day, and most pickle recipes include garlic, dill (usually fine), mustard seed, or onion. A single pickle won't poison a dog but it's far from a healthy snack. Branston pickle is especially problematic — contains onion, apple, and lots of sugar/vinegar.

Does size or breed matter?
Risk with pickles scales with the quantity relative to body weight, so small and toy breeds reach a meaningful dose from a much smaller amount than large dogs. Always check for hidden risk ingredients (garlic, onion, xylitol, excess salt) in any prepared or shop-bought version rather than assuming the plain ingredient name on the label tells the whole story.
