Dog bed - What size reusable/washable incontinence pad?

[PuckyMup]

Anyone know what size reusable/washable incontinence pad fits on half a single duvet?! Am buying DDogs a new bed that is a single duvet folded in half and then in a cover but one DDog has a habit of peeing on beds when she's cross so want to use a washable inco to protect the duvet as best I can. Wondering if anyone has done this and if so what size fits? Said bed isn't here yet so I can't physically measure it.. I know its a long shot

This is probably not much use as an answer as you've already ordered the bed but we chucked our soft beds after one too many peeing incidents! What I do instead is a hard plastic bed lined with plenty of furry vetbed. The vetbed goes in the machine at 60 and the hard bed can be wiped over with antibac wipes or similar. The dogs seem happy and cosy in them.

Could you cover the duvet with a waterproof cover before you fold it in half?

Have a look at vet fleece incontinence pads. Bought mine off Amazon. Reusable and designed for dogs. It's in the car so I can't measure it!

Ah the waterproof cover sounds ideal thanks :) I shall have a look at the fleece inco pads too
