The Micro lifejacket was developed for dogs under 7kg. Just like the standard lifejacket, it combines advanced manufacturing techniques with the best materials available. The lifejacket has been extensively tested to provide the dog with the most ergonomic and snug fit possible. The unique ultra-buoyancy foam rubber is strategically placed around the waistcoat to keep the dog in a natural swimming position at all times. The waistcoat does not hinder the dog's natural movements and is quick and easy to put on and take off. 26-35 cm chest circumference, behind the front legs.
