Two fingers under every strap, then walk him around
Harness sliding sideways? Rub marks behind the front legs? A good fit is snug enough to stay put and loose enough for two fingers under every strap. Loosen everything first, clip the buckles, run the check, then walk him around the room. The PHOEPET Reflective Dog Harness has quick-snap buckles and adjustable straps, so you can dial in every spot and fit it fast.
Biscuit has opinions about getting dressed. Treats settle the debate.
What you need
- A harness with adjustable straps.
- A tape measure if you are still ordering: measure around the widest part of his chest and check the size chart.
- A few small treats and a calm corner.
The fit, step by step
- Loosen every strap all the way before the harness goes on. Loose is easier to slip over him and gives him nothing to push against.
- Put it on and clip the buckles.
- Snug the chest strap first, then the belly strap.
- Slide two fingers under each strap: across the chest, behind the front legs, under the belly. Two fingers slide in easily? Done. Fingers will not go in? Loosen a notch. Fingers swim? Take it in a notch.
- Check the side straps sit behind his front legs, not in his armpits.
- Walk him around the room. Ask for a sit and a lie down. Watch for rubbing, biting or scratching at the harness.
- Treat, clip on the leash, go.
The catch: the first fit takes time. Adjust every strap on the first go and recheck after the first few walks, since straps shift.
