Frequently Asked Questions

Product Questions

Are Pet MatRx supplements safe for my dog?

Yes. Every Pet MatRx ingredient has been investigated and is supported by research and development to be safe for dogs. Our products are formulated by a biochemist and our processes maintain a very high safety standard.

Can I give Pet MatRx supplements to my cat or other animals?

Our current product offerings have been formulated for dogs. We do not recommend giving canine products to other animals.

Can puppies take Pet MatRx supplements?

Yes. Pet MatRx supplements can be given to dogs of all ages, sizes, and breeds. Note: Safe use in pregnant animals or animals intended for breeding has not been proven.

How do I give Pet MatRx supplements to my dog?

Freeze-dried Pet MatRx supplements should be added to food once daily or as directed by your veterinarian. They can also be added to your dog’s water bowl.

How much should I give my dog?

Feeding recommendations are different for every product. Follow feeding instructions on the product label.

My dog is a picky eater. Do most dogs like the taste?

Yes. We do not use any unnatural flavorings, but all our supplements include Bovine Collagen, which adds a natural flavor dogs love.

Do you offer free samples or trial packs?

At Pet MatRx, we understand that random use will equal random results. Consistency is always the best remedy for overall health. A “sample” is just not enough for a dog to achieve results.

How soon should I start seeing results?

Within 2–3 weeks is usually the litmus line. We’ve had results in days and others in months. Your dog is unique, and their result time will be also.

How should I store the product and how long will it last?

The glass amber jar we provide acts as a shield against sunlight which can cause degradation. Keep out of direct sunlight.

Why are products breed size specific and not by weight?

A dog’s digestive system does not grow larger due to weight. Their digestive system size is breed specific. The last thing you want to do is over supplement your 130lb Labrador, for example. If you have a medium size dog by breed, then you get the medium size breed formulation. If you have a “mutt” as we do (Bae), then you can generalize on what a healthy weight would be for their size.
