Some dogs are prone to weepy eyes that may lead to tear stains. But wipes, pads, wash, and drops aren't the only ways you can help with tear stains! Our Tear Stain Bites support normal eye moisture for canine pets thanks to AlaskOmega® fish oil in every chew. Plus, these chewables also feature an antioxidant blend that features advanced Cran-Max®, along with Quercetin, Lutein, and Astaxanthin to maintain normal visual function and may help normal histamine levels.
