How to measure

- Neck girthMeasure around the neck where the collar normally sits.
- Go by the chest. The sizes overlap, so if your pet is between two sizes, choose the larger one.
- Suits small and medium breeds with a chest up to 69 cm.
- Allow 1–3 cm measuring tolerance. Always supervise your pet while it wears a costume.

What owners tell us
We bought the cooling mat for our Labrador during the warmer weather and it's been brilliant. He actually chooses to lie on it instead of the sofa now.
Our 10-year-old Golden Retriever absolutely loves this bed. He settled into it straight away and seems much more comfortable getting up in the mornings. The fabric feels really durable and the bed still looks brand new after a few weeks of daily use. Definitely worth every penny.
I ordered the elevated cat bowl for my British Shorthair and I'm so pleased with it. It looks lovely in the kitchen, feels sturdy and is much easier for her to eat from. The bowls are simple to remove and clean, which is a big plus. Very happy with the purchase.
