My eight-year-old Belgian shepherd had his teeth professionally cleaned about a year ago because they were so stained and there was a lot of plaque and tartar built up at the gum line. Since then, his teeth have started to build up plaque again, they are yellow, and his breath is kind of funky. I figured I had nothing to lose by trying Petlab Dental Formula, but I was dubious about whether it would work. Well, I'm here to say it definitely DOES work, and it's amazing. We've been using it now for a little over a month. Within a week, his teeth were noticeably whiter and his breath fresher. Today I inspected more closely, and there is no build-up along his gum line. Just nice, clean teeth top to bottom. They are not as white as a puppy's teeth, but I don't think they ever could be. I mean, he's an older dog. Like people, his teeth are yellowish. But they are definitely whiter than they were before using the formula, and they are CLEAN. That's the most important thing. Some people are apparently concerned that their dogs won't drink the formula. Have no fear of that. There is no discernible odor. I can vouch for that. I haven't actually drunk the formula, but I doubt there is a taste since there's no odor. And my dog literally laps it up. Every morning, I make a bowl of 8 oz. of water and mix in the required tsp of formula and watch while he drinks it so I know he's had his daily dose. He eagerly drinks the entire bowlful, and then I fill it up to the top with fresh water, which he drinks from all day, filled as needed. Administering the product is easy, dogs like it, and it works. You can't do much better than that. The product is pricey, but if it keeps my dog's teeth clean and keeps us from having to get professional cleanings, it's worth it. Read more

My Chi was 17 when she passed away and she didn’t have plaque. Her vet asked me what I used and said Dixie was the oldest dog she’d ever treated with all of her teeth, had never had a professional dental and her teeth were in amazing condition for her age. I would recommend and am starting on my new 3 year old to get his teeth looking better. Read more

Edited: I had high hopes this product would work, or at least help. It was disappointing since over time we noticed no benefits. I was upset we paid a premium price for the product which in our experience seemed to be useless liquid. We used it for 3 mos @ $30.00 for 8oz. As recommended by the The company. Of course they're going to recommend you buy it again and again @ $30.00 a bottle. We added it to our dogs water daily for 3 mos.. it's didn't help reduce the plaque or help her breath. Customers like you and I know typically, you get a better deal buying a larger quantity of a product. This company doesn't offer a larger quantity at a better price because why would they? they want you to spend more money for less product. I don't like that. And...I'm guessing none of us do ! I'm a verified purchaser. Edited: 10-28-23 Having said all that, I was surprised to be contacted by the company after they were aware of my experience in my review. They kindly offered to refund the recent bottle I purchased. And since that is surprisingly good customer relations, that rates them a couple more stars. Thank you. Read more

I have used this product on a Dutch Shepherd, a terrier, and a chihuahua. Although my DS is gone now, my terrier (12 years old), and my chihuahua (8 years old) have never gotten any plaque on their teeth!! They are still clean and white, and NO, ZILCH, ZERO bad breath. As long as I have dogs I will use this for the protection and dental health of my dogs. I simply add the instructed amount to their drinking water every time I refresh their bowl. Simple, quick, easy. They have never acted as if it has a bad taste. They've never rejected it. Read more

Don’t buy this product!!! I should have read another review before getting this product. Please read the ingredients before using products for dogs from Amazon!!! the labels are usually incorrect and differ from the description on amazon pages!! As someone else mentioned “ The active ingredient in this product is 7mg stabilized chlorine dioxide per 5ml (1tsp) Special Precautions and Warnings When taken by mouth: Chlorine dioxide is likely unsafe. While chlorine dioxide is safely used to disinfect drinking water, it is used in extremely small amounts. The doses used in supplements can cause serious side effects, including severe vomiting, liver failure, and death. Chlorine dioxide is a bleach-like cleaning agent and, if ingested, can have severe, adverse health effects, including death. The EPA has set the maximum concentration in the drinking water at 0.8 milligrams per liter (mg/L) for chlorine dioxide and 1.0 mg/L for chlorite ion. The concentrations of chlorine dioxide and chlorite ion in your drinking water, however, may be lower or higher than these levels. If you have what is considered to be “city water” tap water may already contain percentages of stabilized chlorine dioxide this could possibly cause severe adverse reactions as adding more to a pet drinking water as a teeth cleaning agent can bring the amounts to alarming rates. Drinking any of these chlorine dioxide products can cause nausea, vomiting, diarrhea, and symptoms of severe dehydration. Some product labels claim that vomiting and diarrhea are common after ingesting the product. Be informed and do research before you add anything to your pets food or water. If the water bowl is the only form of hydration for your pet they have no choice but to drink it.” Read more
