No, bearded dragons can’t eat cucumber skins as they can block their digestive tract.
Bearded dragons can eat cucumbers and their skin is fine, but not the cucumber’s skin, so avoid feeding your beardies the skin or the cucumber peels.
What if my bearded dragon eats cucumber skins?
Don’t worry if your dragon eats cucumber skin. It won’t do any damage to them, but it can cause some digestive problems like intestinal blockages.
For example, if the plant passes through the intestine too quickly, there may not be enough time for nutrients to be absorbed into its system. This could lead to malnutrition or other issues.
This applies to other vegetables and fruits too.
Always wash them thoroughly before feeding them to your beardies or you could risk exposing them to pesticides, bacteria, or other pollutants that might be on the skin/peel.
