    Strongly recommend against following recs on bag due to constipation in my cat. I just spent over a thousand dollars at the vet for X-ray, pain meds, enema etc. The instructions say to give 18 treats per day for every 10 lbs. My cat was miserable, constipated and vomiting. Maybe give ONE per day.

    My Mixed (65% chihuahua) breed dog loves these. It is her favorite part of her day. She has been having these once a day (ok sometimes twice lol) since she was 8 weeks old, she is now almost 7 and her teeth are amazing. Her breath is better than most people's. Her Vet is amazed that they have never had to clean her teeth. No issues whatsoever.

      I bought Greenies after my son visited and offered one to my pup. I have never seen her so excited about treats before. I did talk to my vet about them and he said to make sure she chewed them well so there is no blockage. I decided to cut them into small pieces. A petite sized Greenies makes 6 small pieces. She gets only 2 at bedtime and she chews them well. I do recommend them.

      This is just a warning to the consumer. Greenies are a good product, but not for all dogs. When you start to give Greenies for the first time, monitor your dog. I have a large Foxhound, and she started vomiting after eating one. I tried a couple of different times to make sure. It was the Greenies. Sure enough, it was.

      If I could give negative zero stars I would. I have 3 small dogs. A chihuahua and 2 dachshunds. All of my dogs were fine before I started these treats. One of my dachshunds all of a sudden started having explosive bloody diarrhea and puking them up. I will NEVER feed them to my dogs again. I threw away a whole bag of these. He’s lethargic and won’t eat or hardly drink anything. I do not at all recommend these treats to your pets.

      My 10 yr old Yorkie is extremely picky & has stomach issues. He has been getting a greenie when I leave home for years. He loves them and they don't upset his stomach, so I will continue purchasing them for him. I do wish they were cheaper!

      Scheduled a tooth clean. Expensive so stopped feeding my dog Greenies chews. After a few days her teeth were snow white. Figured the greenies were making her teeth brownish yellow. Thought they were supposed to clean dogs teeth.. just the opposite. Happened.

      I gave my dog a Greenies treat and he threw up a few hours later. The vomit was so green and it stained my sheets and mattress. I could not get this green dye out no matter how hard I scrubbed. Made me wonder how dangerous this dye/ingredient/chemical is for a dog's digestive system that I could not wash it out. I will not recommend at all nor will I ever use it.

      Overpriced and turned my dog's poo green. Why do vets recommend them. Kick back, I guess. I won't be buying them ever again and will go back to Dentastix as my dog loves them and there are no side effects.

      I noticed my cat vomiting after digesting Greenies approximately anywhere from 3 to 4 hours and along with that vomiting was hairballs. Was away on vacation. He wasn’t fed any Greenies and he wasn’t vomiting so I decided to stop feeding him Greenies due to causing upset stomach. I’m not saying that every time is going to have this type of side effect but my cat dead and I will feed it to him.
