This excellent and roomy doghouse/carrier is perfect for my 20 lb. dog. The door can be opened on the right, on the left, or it can be removed depending on what you need. You can lift the carrier with the front handle and roll it on the 2 wheels at the back. You can also purchase and mount four castors (1.1 x 1.4") on the mounting spaces if you need to wheel it longer distances.

Amazingly well built pet carrier. Easy to roll on wheels. Great that door easily opens on either side.

I bought the smaller of the two sizes of the Richelle E-Z carrier, although it is still on the large size. The wheels are handy when hauling this roomy carrier with a 26 pound cat inside. The wheels are located in the back so the front must be raised slightly when pulling it. (I use a short strap around the front handle so I don't need to lean over so much.) The top and bottom are attached using 12 sets of screws and nuts which was a bit awkward but I got it done. The door is easy to open and close and I like that it can be easily removed or opened from either side. It was expensive but finding a solid plastic carrier with wheels is difficult. It is also attractive. Delivery was delayed a bit but I blame that on the current supply chain disruptions. Made in Japan.

Durable Worth the money. I recommend this crate to anyone
