    My dogs love these dental chews

    Great for dog teeth!

    We bought these while we were traveling. Our dog had awful looking teeth, covered with plaque. After a few of these, his teeth were so much cleaner! I have to keep buying them. My dog loves them.
    Thank you!

    Bad delivery

    I am very pleased with your product but not sure about ordering again due to Amazon delivery problem. I have a ring door bell and saw the Amazon driver throw the bag from about 4 feet away. The pa Kate landed on concrete porch and broke several of the contents. I prefer to have my dog chew them to break them up, not the Amazon driver. I reported it to Amazon and was told they would not do anything that I was to call your company. Why should your company be responsible for an irresponsible Amazon employee?


    My dog is SUPER finicky and doesnt like most dog treats. Also i am super careful to only give my yorkie FULLY DIGESTABLE products that are healthy . THE MISSING LINK dog chews are a dream come true for both myself and for my dog Benji. As an added bonus the STAFF are wonderful and attentive should you have any concerns. Thank you MISSING LINK may God bless your staff and your company!
