Can dogs eat ginger biscuits? It's best to avoid giving your dog ginger biscuits. Like most sweet treats, ginger biscuits come with a high sugar content. They might even contain ingredients that are potentially harmful to dogs such as macadamia nuts.

Older dogs have weaker immune systems, leaving them much more susceptible to bugs and viruses. Ginger can be used to strengthen a weakened immune system. This herb also promotes blood circulation, flushes out toxins, and also helps to level out low blood pressure, which are all common health conditions in older dogs.

To be on the safe side, feed no more than one-quarter teaspoon to small dogs and three-quarters of a teaspoon to large breeds.

Pickled ginger—aka the kind that's served alongside sushi—should not be shared with dogs. This is because the pickling process includes added sugar and vinegar, both of which can be harmful to dogs in excess (not to mention your dog probably won't like the taste).
