A dog bed that is too small gets ignored, and one that is far too big can feel like an empty field. The right size is simple to find: measure your dog, pick how they like to sleep, and add a little room. Then the bed is something they choose, not something you hope for.

Start with how your dog lies down

The RSPCA says a bed should be large enough for your dog to lie comfortably in all of their natural positions, and that they should be able to stretch out, not only curl up. Watch a few naps first. Some dogs curl into a doughnut, some sleep on their side, and some sprawl flat on their belly with legs out behind them.

Measure standing, from the tip of the nose to where the tail starts, not the tail tip.

How do they sleep?

Bed length at least

80 cm

Bed width at least

54 cm

Size band

Medium

Rule of thumb: dog length plus 5 cm (curled), 10 cm (side) or 15 cm (sprawled), and width about 70% of the dog's length plus 5 cm. This is a common shop rule, not a vet standard, so use it as a starting point and check your dog can stretch out.

Measure the dog, add a little room, and when you are between sizes, go up.

Where the bed goes matters too

The RSPCA suggests a warm, draught-free spot. It also suggests having one bed in a quiet corner where your dog can rest undisturbed and, if you like, another in a family room so they can be near you. If you have more than one dog, give each one their own bed, and a shared one only if they like to snuggle.

Shapes for different sleepers

If your dog tears bedding and swallows pieces, take the bed away and tell your vet. Torn filling can be dangerous to swallow.

What to look for

Prices for dog beds vary a lot. Around €20–50 buys a simple bed, around €50–100 gets a mid-range one, and around €100–150 is the top end for this size.
