Shedding is normal, but excessive shedding or a dull coat can signal that a dog needs more support, and omega-3 fatty acids are one of the most studied tools owners reach for. When we evaluated these supplements we focused on whether the EPA and DHA content was clearly labeled, the source of the fish oil, and how palatable the product was for everyday use. We want to be direct: supplements support skin and coat health, they do not stop shedding entirely, and sudden heavy shedding deserves a veterinary visit to rule out allergies, parasites, or thyroid issues. In our evaluation we recommend talking to your veterinarian before adding any supplement, especially if your dog takes medication. What we like are products with transparent dosing, a recognizable fish oil source, and a form, whether chew or liquid, that fits your dog’s routine.
