my dogs absolutely love these treats, and my wallet does, too! i was quoted $800 for a dental scale/clean for my 9yo dog. on a whim to save my bank account while also preventing him from having to go under anaesthetic and have an operation, i bought these treats. they worked almost INSTANTLY. the hard build up on his molars started cracking off and was gone completely after only 5-6 treats! not even 20 days later (he gets one of these every 2-3 days) and the rest of the build up is starting to flake off, too! being cartilage, i’m not worried about his causing any harm to his actual teeth - it’s just getting rid of all the stuff that shouldn’t be there. plus, his coat is super shiny and i love knowing that his joints are receiving some preventative care. i have recommended these treats to all of my friends and family and will be buying many more in the future!
