Thunderstorms, fireworks, a long drive to the show grounds, a week of visitors. Some dogs just take things harder than others. Tandem CALM+CHILL is a daily powder that supports healthy stress levels and helps your dog stay relaxed and settled. It has no sedatives, so you get your dog, just calmer.

Everyday calm support, made in New Zealand
CALM+CHILL is a high-strength daily supplement from Kiwi pet wellness brand Tandem. One teaspoon sprinkled over dinner gives your dog a blend of calming amino acids, an adaptogenic herb, gut-supporting probiotics and brain-friendly DHA, all on a whole goat milk base.

What’s in each teaspoon (3g)

• L-tryptophan (195mg): an essential amino acid that helps promote relaxation and a balanced mood
• L-theanine (105mg): the amino acid found in green tea, known for encouraging relaxed, settled focus
• Ashwagandha (37.5mg): an adaptogenic herb traditionally used to support a healthy stress response
• Probiotic complex (12 billion CFU) + inulin (450mg): four strains plus chicory inulin, a prebiotic fibre that feeds them, to support a healthy gut microbiome
• Algal DHA (300mg): an omega-3 that supports brain and cognitive function
• Active B vitamins (B6, B9, B12): in forms the body uses directly, to support a healthy nervous system

Calm, not sedated
CALM+CHILL contains no sedatives. It’s designed for daily use, building support over time, so your dog stays themselves: alert, happy and present, just less wound up.

Got a big day coming?
For a known high-stress day (Guy Fawkes, a vet visit, a long trip), you can give a double serve 60–90 minutes beforehand. Do this on single days only, never on consecutive days. Check with your vet before using a rescue dose.

Easy to give
Sprinkle it over your dog’s usual food, or stir it into lukewarm water as a broth. Avoid hot water, since heat affects the probiotics. Most owners split the daily amount between breakfast and dinner.

Also suitable for adult cats (1–10kg): up to 1 teaspoon daily.

A 270g tin holds about 90 teaspoons, roughly a month for a large dog on 3 teaspoons a day, or about three months for a dog under 10kg.
