Dreams involving animals often symbolize different aspects of ourselves or situations in our lives. In your dream, luring animals to their death may represent feelings of guilt, fear, or moral conflict regarding your choices or actions. The act of running alongside them could suggest a struggle between your desires and your conscience.

The horse might symbolize strength, freedom, or a powerful aspect of your personality that you're grappling with. The decision to kill could reflect a significant choice you face, where you feel pressured to make a difficult decision that could harm something you value.

The venomous frog could represent a lurking threat or a toxic situation in your waking life. Frogs often symbolize transformation, but in this context, it might indicate fear of an impending change that feels dangerous.

Overall, this dream could be urging you to examine your choices and how they align with your values. It may be beneficial to reflect on any situations in your life where you feel torn or pressured and consider seeking a resolution that honors your true self. If the dream continues to trouble you, keeping a dream journal and noting your feelings upon waking might help you gain further insights.
