This product slows the build up on plaque on my dogs teeth. I’ve been using it since his last dental and can tell a difference. In my experience it doesn’t get rid of existing plaque but does slow the build up of new stuff. I give it to all 3 of my dogs daily. It’s easy to feed and they don’t mind it in their food.We use this product for several years. Our dog suffers from gingivitis. It definitely improved it but there is still some. For plaque, it kind of help but brushing her teeth on a daily base is necessary.Our dog does not have bad breath and for her age (13) the vet is o.k with the condition of her oral health. Our dog still gets a yearly dental at the vet.I believe a lot of the plaque comes from the high processed food (our dog is on a special diet).Plaque Off is a great product. Every dog is different and I know it really helps when your dog/cat has a bad case of gingivitis or bad breath. I recommend this product for treating your fur-legged friend dental problems.I've been using this product during years and it really help to keep your dog's teeth, gums, and breath odor healthy.When I adopted a second rescue dog (Great Pyr Mix), his teeth were not in good condition. He was only 3 yrs old and his teeth were loaded with tarter and his gums were dark pink/red. The vet quoted me a price of $1,300 for a cleaning. Wow! I hit the internet to research tartar removal products. - Plaque Off is the one I chose. It did wonders for my dogs' teeth. It took a while (a few months) but, his teeth and gums look pretty clean and healthy. There is still a little bit of tartar on the way back upper tooth, but it keeps getting better. I was absolutely astonished and pleased with the improvement. I highly recommend this product.I like that it is easy to use, dogs eat it with their foodI have three rescued Pitt Bulls. I tried brushing their teeth when I got each one home. The only thing accomplished was each dog loved wrapping their big tongue around the tooth brush and sucking off the wonderful tasting new treat. A woman in one of the pet stores recommended this product. The woman was a dog breeder, ushe said her oldest dogs teeth looked just like her youngest dogs teeth because she used this product. The woman recommended I purchase Plaque Off on line for the best price. I purchased the largest container I could find and started all the kids on it using three scoops each for the 50lb. and 65lb. dogs. and four scoops for the 85+lb. puppy. The 65lb. girl was about five years old when I adopted her, and her teeth were not in very good condition. The other two dogs were rescued when they were about six months and 9 months when I rescued them. The 9 month olds teeth were covered with plaque, the obvious result of him only eating canned food. After being on Plaque Off all three dogs have dazzling white teeth. I just sprinkle the product on their dry food each day and they don't seem to be aware of it; The scoop is tiny, only about the size of the tip of a women's little finger. I would give this product 10 stars if I could. If you have an older dog with plaque this product will loosen the plaque so when you do brush the dog's teeth, the plaque will come off much easier. Good quality dry dog food instead of wet food (canned or refrigerated) will also help prevent some of the plaque, but the addition of Plaque Off to the dog food is the complete package. This is a great product.This is a super product! Within a couple of days of using Proden, the hardened plaque that I couldn't get off with a tooth brush came off like simple slime. My dog's breath went from "killer" quality to more normal. I still brush her teeth, but, the plauque comes off with ease. I have tried all kinds of special-expensive food as well as other products to keep her teeth and her body in good health. None really worked..... From nori (it balled up in her throat and ended up on the carpet) to special vegetables (she wouldn't eat them),...or they didn't work real well. Dental bones" (didn't work), Greenies, special "prescription diets".......raw diets (she got bladder stones).etc.......none of these were efficient. Some of the plague products on the market are baking soda and water which is nauseating and adds too much sodium to the blood. The grapefruit seed extract sold to get plaque off is worrisome also, because of its extreme bitter qualities. It can be hard on the body on a continued basis. I consider this to be a keeper!!! She also lost weight with in a couple of days. In Chinese medicine kelp is considered to lower both high and low thyroid. It has a super healthy potassium to sodium ratio as well as other minerals.This SO EASY! It just takes a little scoop as directed in her food.I happen to be a health care professional, so I have learned enough to know that what goes on in the body will often show up on the teeth. Imagine what her arteries would have looked like!! Her blood is now more alkaline.Too, she is calmer, seems happier and sleeps better. Her kidney and bladder stones have dissolved. Even her arthritis is better!!! I just wish I had known about this product a long time ago, it would have saved me a LOT OF MONEY! and a lot of frustration.I really cannot praise this product enough.My dogs had fairly bad teeth and this was entirely my fault as their owner.I turned to this product as really my last hope to get the hard tartar off my dogs teeth other than going to the vets but didn't like the idea of my dogs being sedated just for their teeth being cleaned.You have to be patient with this product though, it will take a few weeks before you see results.If your dog's don't have hard tartar on their teeth then using this and just a finger brush and dog toothpaste is certainly a good routine for keeping your dog's teeth in great condition!If your dog's do have hard tartar on their teeth and you can't get it off no matter how often you brush their teeth, use this for a few weeks (I'm talking 6-8 weeks, might be sooner if you're lucky) then get them a bone to chew and that will easily get the tartar off their teeth!Will be keeping with this product as part of my dogs daily routine now to prevent their teeth getting bad like they used to be!Originally I bought my cat the one with yeast in it that makes them like the taste but the cost of that is stupid.So I bought this huge pack without yeast in the hope he would be ok with it.He doesnt like it mixed with jelly foods but accepts it with gravy foods twice per day.His gums are in a much better state using this.Now been 1 1/3 yrs using this, no problems with rejection and it works.Our 15 1/2 year old Golden Retriever really needed her teeth cleaning and wouldn't let me do it. Because of her age we didn't want her under anesthetic at the vet and our daughter recommended this so we though we would give it a go.Her teeth are so much cleaner now, the yellow stains have gone and her breath is much better. Also much cheaper than vetinary dentist fees that we paid for our other 11 year old Golden Retriever.We put it in their food morning and night and they never leave any in their bowls. It's so easy to use as a very small scoop comes with it and the instructions are clean on the side of the tub. We are on our 2nd tub now and will continue to use it as long as we have our pets.Highly recommend.My Vet recommended this product for my collie 12 Months ago, I have just returned from her check-up & vaccination & there is no discernable improvement. The Vets wife (also a vet!!) said there was no point in purchasing another years supply as studies have yet to show that this supplement actually works!This really seems to work for my dogs teeth, one of my dogs teeth were a bit grotty, however since using this his teeth are much better.The scoop is small, so you don't put so much in that it taints the food, and because you add it to the food it is really easy to use. The scent doesn't seem very strong, and the flavour doesn't seem to alter the taste of the food, as my 2 still eat what I give them.I would recommend this product as I feel it works.
