In a study at The University of Saskatchewan, I observed remarkable improvements in all oral markers using 1-TDC®. The results continue to impress me.

I'm proud to recommend 1-TDC®. My dog, Encore, is living proof. After two years of needing help into our motorhome, she now effortlessly runs up and down the steps on her own. All my dogs now take 1-TDC®.

I started my 11-year-old Australian Shepherd, Summit, on 1-TDC® over a year ago for dental health. Not only do his teeth look great, but he's playful like a puppy again!

FAQs & Reviews
The following are the most frequently asked questions by other caring pet parents like you. If you don't see your question here, we're just a click or a phone call away.
How long until I see the benefits of TDC®?
Each pet is different, but it should be between 2-4 weeks. In some more sever cases, it could take up to 45 days to notice visible results.
Will 1-TDC® replace my dog's need for regular dental cleaning?
Teeth cleaning is important for removing tartar and plaque from your dog's teeth, an important part of oral health. 1-TDC® keeps the gums healthy, the major element of oral health. Ideally you want to do both. 1-TDC® complements teeth cleaning and other oral care procedures.
Can my dog with a beef allergy use 1-TDC®?
Yes. Allergies come from protein, and 1-TDC® is a fatty acid. So, any animals allergic to beef should be safe. Of course we recommend you consult with your veterinarian first who has a full medical history of your dog.
Are there any side effects of using 1-TDC® long term?
There are no known side-effects or contraindications with other medicines or products. 1-TDC® is intended for long-term use in dogs and cats throughout their life and they will not develop any resistance to the product.
Can I use 1-TDC® if my dog has health issues?
Like all other supplements, if you have a health issue going on with your pet, it is always recommended to discuss any treatments with your veterinarian. One case where you would not use 1-TDC® (and most other products) is if there is an active case of pancreatitis occurring.
Can I use 1-TDC® if my dog has health issues?
Omega 3 fish oils provide great general health benefits. However, when it comes to joint health, 1-TDC® provides superior results. Also, fish oils provide very limited periodontal benefit. Therefore, continue to use fish oils for general health and add 1-TDC® for superior gum and joint health results.

Customer Reviews
I am very happy with the results of this product. I have been giving it to my four golden retrievers for over three mo. and there is a huge difference in their teeth. I took my four year old in for an exam because she is training to be a therapy dog. The vet said she had no tartar on her teeth at all. I see improvement on my other dogs too. Great Product. I have already told several friends that have dogs about this wonderful product.
My girls (3 yr old Aussiedor, 11yr old Labrador Retriever) were initially very skeptical of the whole “rub it on the gums” approach and certainly had no idea of what those little red capsules were! After just a couple of days they learned to allow me to apply the contents (and now look forward to it!) and then snarf down the hearts. It has been a couple of weeks and while I know it’s still a bit early for solid results, my husband has already noticed our old girl has more pep in her step and has actually become playful again! She has moderate/severe arthritis in her rear end and a couple of her front toes. I tried Librela but didn’t like the side effects. She is currently on daily Rimadyl but am thinking I might be able to go to “as needed” doses in the near future.
My young one is my agility partner and I give it to her to maintain muscle/joint health so we can partner for many years into the future.
my dogs love it and their teeth look good.
It’s still early, but my 13 year old rescue golden girl breath, has gone from horrible to just kinda stinky! She loves the flavor and doesn’t fight at all when I squeeze the “juice” onto her teeth. She loves eating the capsule. It’s only been a week, but I’m cautiously optimistic!
My 12 year old Pit mix has a bilateral CCL tear and secondary arthritis. I’m happy to say that 1 TDC has really helped her mobility. I started noticing a difference about one week of taking the little capsules.
