A healthy liver is important because it detoxifies any chemicals or pesticides our dogs may be exposed to, toxins in food they scavenge, and chemical prescription drugs.

My wonderful Aussie, Kira, started to not eat. It was a battle to get her to eat anything. And she started losing weight... She just kept getting worse and then one night we came across your web site that spoke about liquid milk thistle. So we started using it and slowly but surely she has gotten so healthy that you would not even know she is the same dog.

Advice from our on-staff veterinarian:

The liver performs dozens of different functions in the body, including clearing out toxins. Yet liver disease (including cirrhosis) is one of the most common health problems in older canines. It can damage all functions of the dog’s liver, with very harmful health effects.

Even canines without liver disease may need support to metabolize and excrete prescription medications, which are often damaging to the liver. Milk Thistle is an excellent way to support the liver to deal with this toxic load of medications. It is not contraindicated with conventional medications and it is gentle enough for long-term use.

While some Milk Thistle sold in health stores is can be alcohol-based and should not be given to dogs, Pet Wellbeing's Milk Thistle is glycerin-based and safe for dogs.

Milk Thistle should be administered to every dog taking liver-taxing medications and especially if the liver is damaged or diseased.

The active ingredients in Milk Thistle are known collectively as silymarins.

These constituents:

  • Help maintain the health of your dog’s liver.
  • Scavenge for harmful free radicals.
  • Help guard against toxins trying to bind to the dog’s liver.
  • Support the stability of liver membranes

As an anti-oxidant, silymarin is even more effective than Vitamin E. It also helps support the production of new liver cells in dogs.

Milk Thistle provides useful health support when your canine is being treated with things like:

  • Anti-inflammatories:  NSAIDS and Steroids
  • Chemotherapy drugs
  • Bile acid (ursodiol)
  • Immunosuppressants
  • Seizure medication
  • Sulfa antibiotics
  • Daily heartworm medications

Milk Thistle is gentle enough for long-term use.

Healthy Nutrition Tip for Your Dog's Liver 

Processed foods stress your dog’s liver as it attempts to detoxify the preservatives and other additives like artificial flavors and colors. Go natural! Avoid grains and focus on healthy proteins from free-range, grass-fed animals. Green foods will help detoxify your canine's liver, such as those you will find in Pet Wellbeing's SPARK. Expect your dog’s moods to be lifted as well! SPARK is a veterinarian-formulated, daily nutritional supplement for dogs of all ages.
