Washing and preparing cucumber skin

Before feeding cucumber skin to your dog, ensure it is thoroughly washed to remove any pesticides or other contaminants. Also, remember to cut the skin into small, bite-sized pieces to minimize the risk of choking.

Introducing cucumber skin to your dog's diet gradually

When introducing cucumber skin to your dog's diet, start with small amounts and gradually increase the portion size over time. This will give your dog's digestive system a chance to adjust to the new food.
