One of the best ways to help your dog with anxiety, according to Nichols, is by learning about classical conditioning — and putting this into practice through work with a professional, certified dog trainer. "It's not that it's harmful if you do it incorrectly," Nichols explains, "It just won't work as well." You and your dog will both be frustrated, whereas a qualified dog trainer will help you both find what works. And of course, having a partnership with your dog's vet is always advisable. Discussing the option of a behavioural medication with your vet to help your dog cope with anxiety may also help with training.
