PAW Complete Calm is a daily calming chew for dogs of all breeds and sizes, from Blackmores' veterinary range. It replaces the older Multi+Tryptophan formula with doubled levels of tryptophan and B-group vitamins per chew. Aimed at dogs prone to nervousness, anxiety around noise or travel, or general excitability, it's given as an ongoing supplement rather than a one-off sedative.

Each chew delivers a high dose of tryptophan — an amino acid precursor to serotonin — alongside vitamins B1, B5 and B6, which support normal nervous system function. The base is a fish and chickpea chew, so it avoids the beef and chicken proteins some dogs react to. Effects build up over consistent daily use rather than working instantly, so most owners give it for a couple of weeks before judging results.

Owners tend to reach for this when they want a non-prescription option to sit alongside training and environmental changes for an anxious dog. The palatable chew format makes daily dosing straightforward, and the fish and chickpea base suits dogs on limited-ingredient or novel-protein diets.
