Helps relax her
Works great. My dog is a Cavalier King Charles Spaniel, just over a year old. Has pretty bad separation anxiety but these help a lot. Other times if she’s just a little worked up I give her half a chew and she usually calms down enough to sit down and relax. I was worried she wouldn’t like the taste because she is a bit picky but she actually seems to like them. Highly recommend.

Calming chews
Work really well for my Chihuahua while I trimmed her nails. Only gave her a quarter because she is less than 5lbs.

Concerns at first!
I was. little worried when I gave my dog these because she was knocked out but once her body adjusted to taking them, she doesn’t shake at all during thunderstorms. They are perfect for dogs and they really do work.

Helps the doggo
Helped with his anxiety and fear. Less shaking, less whining, less hiding. Not perfect but better than nothing. Started with 3/4 since he is 13 pounds. Switched to whole one once I saw he was fine with it stomach wise. Will use for July 4th days and again for new years fire works

Scam
Product is great. Amazon not so much! Bought during an Amazon promotion buy $100 pet products and receive $30 credit. How the hell do you contact Amazon to get the $30 credit? SCAM!!!

Doesn’t seem to help calm my dog.
My new dog gets separation anxiety when I leave the house and my dog trainer suggested I put him in crate and give him l-theanine before I leave home. I bought this product because it contains l-theanine however it seems to make my dog hyperactive instead of calming him down. I gave it to him before putting him in the crate when I went out for an appointment . When I returned a couple of hours later and let him out of the crate, he was very hyper for over an hour.The 2nd time I gave it to my dog I stayed home. It did not make him hyperactive but it didn’t seem to calm him at all. I previously gave him a different product that contains CBD for dogs treat before putting him in the crate and when I returned home he was fine. I think l-theanine isn’t very effective for my dog. Don’t know if it’s the product or just my dog.

3 dog house preferred calming
Have three dogs. Helps them calm knowing we are leaving. They love taking it. Tried many others but they didn’t take to it. Value of this purchase was just right having 3 dogs. No diarrhea, they love the taste. I’ve always loved the Greenies product. Happy to find calming with them.
