With extracts from soothing herbs including passionflower and lemon balm, this powder supplement can reduce stress and manage anxiousness in dogs. It’s fortified by L-Theanine, which helps to alleviate anxiety, and two forms of Vitamin B. Though this supplement is also available as a soft chew version, this powder is easy to add to your pup’s food.
While pets parents will be interested to learn of the active ingredients list — L-Tryptophan, L-Theanine, organic passionflower and organic chamomile can all help to calm stressed dogs — your pup’s attention will no doubt be focused on the beef liver, bacon and cheese flavor of these soft chews. This product is certified by the National Animal Supplement Council (NASC).
These soft chews — also available in turkey flavor as well as peanut butter — contain L-Tryptophan, passionflower, chamomile and valerian root but also melatonin, which is known to reduce stress and anxiety. Give the correct amount — depending on your dog’s weight — 30 minutes before an unexpected stressful situation, such as travel.
This peanut butter spread includes L-Theanine, L-Tryptophan, chamomile and valerian root, as well as GABA (gamma-aminobutyric acid) which can help to manage stress and has a calming effect. It comes in a squeezable pouch, so you can spread it onto toys your dog likes to chew, or mix it directly into food. Because licking is a soothing behavior for dogs, this product added to a lickimat or Kong can be effective.
With a Probiotic and Prebiotic blend — including beta glucans — fortified by passionflower and magnesium, this supplement can help to regulate stress response and balances the gut-brain axis. It’s been formulated and developed by vets, and has no fillers or artificial flavours. It’s also chicken and grain free, which can be beneficial for some dogs with dietary sensitivities.
These chew sticks are primarily effective for helping to calm nervous dogs, thanks to ingredients that include melatonin, L-Theanine (present as Suntheanine), chamomile and hemp seed. However, as an additional bonus they can be given to your dog to help promote good dental health; the peppermint flavour can freshen bad canine breath. Chewing is a calming behavior, so again, the chew format has a benefit.
