Who is K9+ Calm for?

Your dog gets anxious around travel, fireworks, thunder, or being left alone
Everyday moments e.g visitors at the door, car rides, vet trips feel more stressful than they should
You want your dog to feel settled, not sedated

Why take K9+ Calm

Loud noises, car trips, and time alone can feel overwhelming for some dogs, showing up as pacing, whining, excessive barking, or restlessness. If that sounds like your dog, their nervous system may be missing the nutritional support it needs to stay settled.

O2B K9+ Calm™ is formulated to support:

A balanced, adaptive nervous system so everyday triggers like visitors, vet visits, or being left alone feel less overwhelming
Normal responses to stress with amino acids like L-Tryptophan and L-Theanine, known for their role in promoting calm, focused behaviour
Resilience during stressful situations such as travel, fireworks, and separation, with adaptogenic herbs like Ashwagandha and Valerian Root
Restful, settled sleep through traditional calming herbs like Passionflower and Chamomile, alongside gut-health support from Fermplus probiotics known to play a role in managing stress responses

For best results, we recommend using K9+ Calm™ alongside obedience training, consistent routines, and other positive behavioural support.

Works fast and settles them down

Both my English Staffy X and German short-haired pointer take K9+ Calm. Works fast and settles them down.

The only one that's worked!

My border collie was attacked and subsequently traumatised when we took her out in the car one day. I have tried all types of supplements to relieve her anxiety when she gets in the car, none worked except O2B K9+ Calm. So grateful! Thanks

Much happier dog!

Poppet our working dog lost her best little buddy and has been miserable and anxious since. She's now taking K9+ Calm and is a much improved, happier dog all round. Thanks O2B!

Works wonders!

Mave our border collie is an anxious wee thing. K9 Calm is working wonders for her!

Far more relaxed

My ex-agility dog has been terrified of thunder and lightning since the Kaikoura earthquake. I’ve been giving him 2 of the O2B K9 Calm a day morning and night with food, and he’s definitely far more relaxed and less easily frightened!

Worked really well when she needed it

Our beautiful little dog passed away recently at 16 years old, and she was quite anxious near the end, but K9 Calm really helped her and we're very grateful for that. She wasn't one for chewing down many tablets but must have known she needed these ones. Thanks O2B
