But we have this huge jacuzzi in my bathroom.....my yorkie is 6 weeks old. AND HE lives/ sleeps in it!
It works perfect! I shut the water pumps off (for safety) and made a super comfy bed at one end, a toy area, feeding area, and at the other end of the tub - I laid poo-poo pads. He sleeps and plays....and then walks over to potty area to do his poo-poo business!
Because the jacuzzi has smooth, high walls, he can't crawl out, and my kids and I love leaning over and watching him from the sides.
OK, obviously this will only work for about a month. So I bought a puppy bed and travel crate too. When he's big enough tho.....he's gonna sleep with me in bed
