Size guide

A harness that is too big is under the dog by the first hedge; one that is too small never leaves the cupboard. All that stands between the two is five minutes with a tape measure, ideally while their nose is in the bowl: chest girth just behind the front legs, tape resting on the coat rather than pulled tight. Measure rather than go by breed or weight, because two dogs of the same weight can have very different chests. A harness that spins is almost always one size too big; we have already made that mistake for you.

How to measure your dog

• Chest girth: run a soft tape measure around the widest part of the ribcage, just behind the front legs. The tape should touch the coat without squeezing.
• Neck girth: measure where the collar settles of its own accord, at the base of the neck, with two fingers slipped between tape and neck.
• Standing: take the measurements while your dog is standing and relaxed, not sitting or lying down; a bowl or a treat helps them stay put.

Three things to check before ordering

• Between two sizes? For a harness, go one size up: the straps adjust down, not up. For a collar, check that the measurement falls in the middle of the range.
• Thick or seasonal coat: measure over the coat as it will be worn; a clipped dog, or one that is shedding, can move from one adjustment range to another.
• Growing puppy: choose a model with a wide adjustment range and measure again every 4 to 6 weeks.

Stuck between two rows of the table? Send your dog's measurements to contact@rundavo.com and a human replies within 24 working hours with a size, not a catalogue. And if the size is not right, you have 14 days to send it back, no sighing (see Returns).
