Decent supplements. It’s good to know the brand is from a reputable company.
We’ve been using these for about a month for our dog. She can be quite a handful sometimes and that might be because she’s only six-months old and has a lot of puppy-ness.But, she also has an upset stomach fairly often. Our vet said the breed is prone to sensitive stomachs and recommended some Purina biotics powder along with canned pumpkin to mix with her food. It helped, but she would still have bouts every couple weeks.We switched to these and they seem to work about the same. It’s not easy to know if it’s due to these chews or if she’s just growing out of it.The calming effect of these chews is also difficult to evaluate. She’s got a lot of puppy energy still, but she definitely seems calmer than she used to be.One noticeable change is that she’s sleeping through the night without needing to go out at 3 AM.The ingredients are the usual kinds found in calming formulae tryptophan, melatonin, etc. Innocuous but with research to back up the calming effects. So far, we haven’t seen any negative affects for our puppy.It’s not a miracle cure, but our vet said there’s no reason not to try them.The current $35 for a 30 day supply might seem a little steep, but it’s really a 2-in-1 supplement. It costs less per dose than the Purina biotics powder — and if it works, it’s a fair value. It’s priced similar to other dog supplements.Overall Summary: This is worth trying if your dog has a sensitive stomach and could use a little calming. Five stars.

Probiotics are good
I have a 60 lb golden retriever that suffers from regular night terrors. She does not have daily anxiety and is not afraid of thunderstorms. She eats a high quality kibble but does have occasional loose stool. I thought I’d try these to see if they would help before bedtime for her night terrors. They do not but they do help firm her stool. For her weight, I give 3 per day so it’s a month supply. She likes them. No horrible odor. Bite size. Easy open canister. Since she’s not getting the full effect from them, I probably won’t get these particular ones again but ones geared more just for gut health.

No go for us!
I had high hopes that this would help but our dogs won’t eat them.

Doesn’t work for us, dog didn’t like
I have a Maltese-Yorkie, and my dog did not like these at all and will only eat them if properly masked and he didn’t see me put it in there. Otherwise he will hunt it out and pluck it out. He’s normally not picky but he either doesn’t like the taste or the smell. They seem soft & chewable enough that they wouldn’t be hard on his teeth, he’s old. Overall, I have not noticed any difference in him with this product so maybe it doesn’t work for him. Regardless of the cost, if it’s ineffective and not liked, there’s no real value there

Not for picky eaters
I cannot say whether these are effective or not because my dog refused to eat them. My dog isn’t that picky so that tells me that these must have had an icky taste because she spit it out immediately. I would say for the price range they are worth a try, but I just couldn’t get my fur baby to eat them.

good probiotics
Great product. My Dog is very fussy regarding her GI system. She has chicken allergies and when she was a baby had frequent loose stools. As a result I regularly give her Gi supplements like this and probiotics whenever I can. I can say she eats this very easily and it helps with her stools. She isn’t as fussy and it helps her digestion. I really recommend for dogs with sensitive GI systems

Good soft chews
These seem to work for my dogs. They do help calm my dogs down but not for long. I like that they’re packed full of probiotics, probiotics, and post biotics. No issues with the digestion with my dogs but they don’t always want it.The smell is fine and has a slight Fruit smell to me. The supplements are a good size and shape for small to large dogs.

They work, but be very careful with dose
Work well for anxious puppers. Ours seems to be okay with the taste, though we do add on a dab of peanut butter or break it up and add it in to moist food. For the dosages, it’s better to start low and not go with the full dose on the label. You don’t know how your dog will react if they’ve not been given melatonin, ashwagandha, L-tryptophan, and L-theanine before. For large dogs 76 – 100 pounds, it says four chews. For a dog never exposed to these ingredients before, this can be way too much. Start with maybe just one or two chews at first. Our Min-Pin hadn’t had these ingredients before, and we have her half a chew during the Fourth of July since she’s only 14 pounds. Half a chew was enough to put her into a sedated zoned out state for almost 24 hours. We actually took her to the vet to make sure she didn’t need anything to counteract the active calming ingredients. That’s when our vet told us to never go by the label when it comes to using calming supplements like this. Her advice was to give a quarter of the dose for small dogs, and no more than half the dose for large dogs (we have both). The next time we have her one of these chews, we cut it into eight pieces and started with just one piece. The vet said as our dogs get more exposure to these ingredients, they won’t act so sedated for so long.
