ThunderEase Pheromone Diffuser

The verdict

The passive option, and the one that requires nothing of the dog. It uses the ADAPTIL pheromone analogue — a synthetic version of the appeasing pheromone a nursing mother produces — released continuously from a plug-in, in a 90-day kit. Drug-free and, as the maker notes, not affecting humans or other pets in the household. ThunderEase cite over 80 per cent of surveyed owners reporting improvement; again, owner-reported. The most useful applications are the ones where you cannot easily be present: a new puppy's first fortnight, a house move, a rescue dog settling in, a senior with new night-time restlessness. The rating is middling, which suggests the effect is subtle or absent for many dogs. Plug it in where the dog actually sleeps, not in a hallway, and give it a couple of weeks.

Drawbacks

• Only affects the room it is plugged into
• Middling ratings suggest the effect is subtle at best

Specifications

Specs come from the manufacturer listing and Amazon’s public product data. A field that reads “Not stated” is one we have not verified — not one the product lacks. We research and analyse; we do not test products on dogs.
