Generally, a dog licking you will not break a fast.
Fasting typically refers to abstaining from food and drink. The provided reference explicitly states that only eating, drinking, and masturbation break a fast. A dog licking you doesn't involve the ingestion of anything, therefore it doesn't interrupt a fast.
Understanding Religious and Medical Fasting
It's important to note that the definition of "fasting" can vary depending on the context.
- Religious Fasting: Specific religious practices may have stricter guidelines than simply abstaining from food and drink. Some may prohibit certain activities or substances beyond food and water. Always consult religious texts or leaders for clarification on specific rules.
- Medical Fasting: Medical fasting, often for tests or procedures, typically involves much more stringent rules than casual fasting, and should always be guided by medical professionals.
The reference provided focuses on a more general definition of fasting, and within that context, a dog licking you is irrelevant to whether or not the fast is maintained.
