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.



The liver performs dozens of different functions in the body, including clearing out toxins. Liver support is common for in older canines.

Many canines may benefit from support to metabolize and excrete prescription medications, which cause the liver to work harder. Milk Thistle is an excellent way to do this. 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 glycerine-based and safe for dogs.

Milk Thistle should be administered to every dog taking liver-taxing medications and for any other reason the liver may benefit from support.

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

These constituents:

  • Help maintain the health of your dog’s liver.
  • Supports excretion and metabolism of medications.
  • 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 taking any 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 flavours and colours. Go natural! Avoid grains and focus on healthy proteins from free-range, grass-fed animals. Green foods will help natural detoxification for 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.


Milk Thistle must be glycerine-based to be safe for dogs. Do not give your dog any supplements that contain alcohol.
