How to fit a harness properly on a long-haired dog?

On a dog with a thick coat, straps can almost disappear. A harness looks fitted when it is mostly resting on the volume of fur; on the other hand, you may be tempted to tighten it too much so that it looks stable.

To check the fit, rely on where the harness sits and on what you can feel, not just on how it looks.

Measure without relying on the volume of the coat

Stand your dog up and follow the manufacturer’s guide points. The tape should measure the body without floating above the fur or squeezing your dog.

Do not add an arbitrary margin “for the fur” if the guide does not ask for it. If in doubt, send the measurements to the seller and mention that the coat is dense.

Check under the straps

Once the harness is on, gently move the fur away from the clips before closing them. Make sure no tuft is caught in a buckle.

Then slide your hand under the accessible areas to check the fit as described in the instructions. The often-quoted two-finger rule is only a rough guide: on its own, it does not prove the harness is suitable.

Watch your dog walk

A few calm steps will show whether the harness moves a lot or seems to hinder movement. After taking it off, look at the contact areas, especially near the front legs.

The American Kennel Club recommends in particular watching for rubbing and re-checking the fit after grooming or a change in weight.

Should you readjust after grooming?

Yes, it is worth checking. Losing part of the coat’s volume can change how the fit feels.

Also get into the habit of checking the clips and straps before walks. If you notice redness, pain or lasting discomfort, do not try to fix it only by tightening or loosening: have it looked at.

A thick coat can hide the contact points. Taking a moment to look at them helps spot a problem earlier.
