48"x 48" Whelping Box Kit for Dogs and Puppies with Rails,Suitable for Large/Medium Dogs,White

It’s a little small but definitely on the right track, floor space is 10 feet (5x2), care guideline is 18 (6x3). These dudes are crazy active. That’s an encouraging budget for a tank! Here’s some alternatives well within that budget. Here’s a grow tent with 16’ of floor space. A little less than 18, but you could always put a little ramp hide for a short platform that adds a bit more space. If you don’t like the look, then this has the same floor space and you can connect a pond liner underneath to keep dirt in. Just have to keep an eye on humidity since it’s open to the air
