How quick do they start working in my dog after I give him one? My dog howls non stop whenever I leave the house whether it's to the gas station for 15 mins. or an appt. for an hour or more. We're home together otherwise 24/7 so I realize he's attached.

Rated 5 out of 5 by from Calming formulaI have a large dog that does not like loud noises. We have had a very wet, noisy summer. It is to the point when he hears the rain he starts shaking and pacing and tries to jump up to sit on your lap. Riley is over 90lbs. I started giving him The Ulta Cruz calming chews and they have helped him greatly.

Rated 3 out of 5 by from Results Still OutI'm not sure the results are favorable for this product. I realize my blue heeler is still in her puppy stage at 1-1/2 yrs old but I was hoping this would help settle her down some.

Rated 5 out of 5 by from Really worksBought this for my male dog who is high energy and nervy. Since i was having trouble with him focusing I bought this to see if it might help. It did and i can see it in his eye for they are red in whites when he is not on it. Like a person with high blood pressure. When I give him his dosage twice a day his eyes look normal and he is not running here and there so much. Much calmer in house as well as outside.

Rated 4 out of 5 by from I think she is doing betterI got this for our red BC she gets barky at night going out the door and scares the other dogs. I wanted to say yes it is working great, she had a couple days no bark...but its back but I feel it is not as bad as it was....Im sure it would work for dogs with other issues she is just getting older and has this issue..vet said it would probably never go away...

Rated 5 out of 5 by from Great product and it works.Used for our last dog during thunderstorms. New puppy gets car sick and we're getting ready for camping season. I hope this will help her over the training period. We haven't had thunderstorms yet so best to have them on hand just in case.

Rated 5 out of 5 by from Calming SupplementI am very pleased with this product. We have an American Leopard Hound that is terrified of storms. With the first sound of thunder she heads to her bag of Calming Supplements. Calms her down quickly. Don’t plan on being without a bag.
