Potential Long-Term Effects: Prolonged consumption could potentially lead to more serious health issues, such as cancer. However, more research is needed in this area.

What the ASPCA Says

The American Society for the Prevention of Cruelty to Animals (ASPCA) doesn't list food coloring as toxic to dogs. However, they advise avoiding foods that contain excessive amounts of dyes, as they might cause stomach upset.

Therefore, while green food coloring might not be immediately toxic to dogs, it's safer to avoid it, especially if you're unsure about the manufacturing process or your dog's tolerance.
