Verdict

We think that the VetriScience Composure Calming Chews are a solid choice for moderate anxiety in dogs and even cats, especially if your pet responds well to natural ingredients and tasty treats. If your dog has severe anxiety or doesn’t accept the taste, you might want to consider alternative calming options, such as chews with a different formulation or adjunct therapies. For those looking for a highly effective solution during thunderstorms or car rides, understanding your pet’s individual response will help determine if this product suits your needs.
