Does this product exist? Bed extender?!

[Nameeechanged]

My dogs are loveable knob heads who have decided the only place they will sleep is in our bed. Dog training issues aside (which I need to tackle when I have more mojo) is there something I can clip on the side of my bed to make it temporarily bigger?! They won’t settle on the floor, they want to be right in the middle of me and my husband…… and there’s 3 of the buggers!

(this started when they came on the bed when I had cancer, and now I’m well again, but the stubborn buggers have had a taste of the good life!)

All I could think of would be one of the next to me cribs, or even an ottoman at the end of the bed?

If you have the space could you get a single bed of the same height and set it up right beside your bed?

Yeah, I’d thought about a next to me crib but ideally I’d like it the full length of the bed as I suspect it will be me on that part! An otterman at the end is my current plan B, but I need to train them to sleep down there next. I genuinely was considering separate bedrooms so we could divide and conquer, but that seems ridiculous for 3 pugs!

Sadly not, we are in a new build so it’s not a massive bedroom. My husband’s right by the en-suite, and I have a chest of drawers width (a small one!) between me and the wall. I would love there to be a clip on extension thingy with about an extra foot of mattress attached!

You mean this sort of thing?
