Hairballs occur when ingested hair builds up in the digestive tract, often causing discomfort, regurgitation, or constipation. Though more common in cats but can also affect dogs—especially those with longer coats or excessive grooming habits.

Animal Essentials’ Hairball Relief Herbal Tonic uses a single, effective ingredient: organic marshmallow root, traditionally used to support healthy hydration and mucous membrane function in the GI tract. By promoting healthy movement of ingested hair through the GI system, marshmallow root helps reduce the likelihood of hairball formation and subsequent digestive discomfort.
