• FOR LIVER WELLBEING: The filtering of toxins that the liver performs is critical. If it becomes clogged with toxins itself or is damaged in any way, your pet can experience any one of a host of potentially life-threatening problems such as liver disease and the slowing of metabolic processes. This pet milk thistle helps detoxify and cleanse the liver so it can most effectively do its job while increasing general immunity of your dog or cat.
• TASTES GREAT: As this is a milk thistle liquid for dogs and cats, you simply squeeze a few drops into your pet’s food, and they will enjoy it just as much as their breakfast or dinner. Meanwhile, the silymarin will go right to work providing a complete liver detox for dogs and cats alike.
• BROAD-SPECTRUM SUPPORT: While not a Cushing’s Disease treatment for dogs, “dog milk” can help lower the high cortisol levels associated with the disease. Through its effectiveness as a dog kidney failure treatment and canine appetite stimulant, milk thistle helps keep both the liver and the kidneys operating at peak efficiency.
• MADE THE RIGHT WAY: We source the highest-quality milk thistle, then we extract the potent silymarin responsible for its liver detox properties into a liquid form with the highest bioavailability suitable for ingestion by dogs and cats. We manufacture our cat and canine milk thistle right here in the USA. We feed it to our furry companions, and we hope you’ll feed it to yours.
• FURFINDS COMMITMENT: We’re all in the same boat; we want to ensure our pets live a long happy life.That is why we are committed to make the best possible products for our furry customers.
