Pets get stressed, too! CALMING for Small Dogs is recommended for pups exposed to increased environmental stressors, like a holiday party or a long car ride. The Colostrum Calming Complex, which supports stress reduction and cognitive function, works synergistically with L-theanine. This naturally occurring amino acid helps the body produce other amino acids like dopamine and GABA, and has been studied for its ability to curb destructive behaviors often associated with stress, without causing adverse affects or drowsiness. B vitamins like thiamine support calming and relaxation, as well as normal energy levels. CALMING for Small Dogs can be used daily or when extra help to relax is needed.
