Jennifer Ng DVM’s dog, Willow, can finally relax through the New Year’s fireworks. She’s my only dog who gets anxious with storms and fireworks. Gave her a dose of clonidine and a couple of Composure Pro chews a little before 6 pm, and that, combined with background noise (TV and music), has kept her calm all evening. Willow has been my guinea pig, and we’ve tried a number of different supplements and medications over the years. This works as well as the FDA-approved Sileo, which is in the same drug class. While the clonidine takes a little longer to kick in, it also lasts longer.
