If it helps any, we have the size 'medium' for Milli. There's plenty of room in there for her pillow, a puppy pad, food and water dish, and her toys. The medium size has a diameter of approx. 45 inches. So, you'd need to judge whether you have space for it. I'll attach a photo of Milli in her playpen so you can see how large it is compared to her. She weighs about 6 lbs. so is a little larger than Tilly. |
