These didn’t phase Bella but Bella is very high strung. She is a frenchton but I think she is mostly Boston. I walk her 3 times a day on the weekend & have a dog walker during the week. I have to walk her in the dark when I get home. I’m not sure this isn’t a good product, just not good for Bellaboo.

Actually calms him

He doesn’t love the flavor, but better than other calming supplements we’ve tried and he eventually goes back to eat them. Definitely notice a difference in temperament

He doesn’t love the flavor, but better than other calming supplements we’ve tried and he eventually goes back to eat them. Definitely notice a difference in temperament. Anxious 10 month old and these help with separation anxiety

Soft little bites - highly recommend!

These are Thor's new favorite. We had to find a substitute when his calming bites were discontinued. They are very soft, easy for him to chew with his 14 year old

These are Thor's new favorite. We had to find a substitute when his calming bites were discontinued. They are very soft, easy for him to chew with his 14 year old teeth (what's left of them anyway lol) and I like the ingredients.

Great Jacks calming grain free dog treats

Got my very hyper dog to fall asleep at night and she stays asleep until 6:00 AM. No problems getting her to eat them either.

Does not calm

It's just the name of the product. Unfortunately it does not calm the dogs.

We have been giving our 10-year old dog a different brand of calming pork liver supplements for over a year, calling them "Sleepingtons: Nature's Lullaby" and giving them to him as a nighttime treat. They were suddenly discontinued and we panicked - he LOVED them. I googled a replacement and found these. We held our breath when we gave him his first new "Sleepingtons" hoping he'd like them. He loves them! Crisis averted, we remain in good graces with our boy, and we get to support a Canadian company instead of a giant US-based retailer private label. Win, win, win!
