Verdict

ThunderWunders Hemp Dog Calming Chews appear to be a popular choice for managing situational anxiety like storms and fireworks, especially when given consistently and in appropriate doses. They are well-liked for their taste and gentle formula that avoids digestive issues. However, results can vary widely depending on the dog's specific anxiety type and severity, with some pups showing little to no benefit. If your dog struggles with severe separation anxiety or non-responsive anxiety, you might want to consider additional or alternative options tailored for those needs. Overall, these chews are a solid, vet-recommended option worth trying for situational anxiety and calming support.
