I love PetEgo’s products, but I’m disappointed by this one. It has great features: It rolls, it has an optional internal divider that allows two (tiny) dogs to share it, it expands with a zipped gusset to provide substantial additional space. It converts to a backpack. It has lots of mesh ventilation panels. These are all excellent things, and when you add in PetEgo’s quality design and workmanship, you’ve got a great carrier. At 9.5Hx21Lx15W, however,  it’s…

Pet Gear offers a line of I GO2 rolling carriers that convert to backpacks. The bags all have straps on the back through which a safety belt can be fastened, so they will work as car carriers too. The manufacturer would like you to unzip the main window and regard the carrier as a car seat as well, but in that case only the small…

Sleepypod’s carriers charm me. They come in two sizes (regular, and the Sleepypod Mini), and they’re designed to address several needs at once. The base can be used as your dog’s everyday bed; add the mesh dome, and the bed is ready for car travel (pass the seatbelt around the base and through the top handle) and, potentially, air travel.

Both sizes of Sleepypod exceed…

In an earlier post, I reviewed Creature Leisure’s Carry Den XT, which has backpack straps. The regular Carry Den, however, is also an excellent product. It is as well-made and well-designed as its XT cousin, but it has only handles and a shoulder strap for carrying.

The Medium size (9Hx17Lx10W) is pretty close to the major airlines’ maximums, and would likely work very well for in-cabin use. The…

Our Pet Pilot XL arrived yesterday, and I think we may have found the rolling airplane carrier we’ve been looking for. In its normal configuration (9Hx19Lx14W), the carrier exceeds the airlines’ maximum sizes, but it’s just barely workable nevertheless (please note that it lies horizontally in the under-seat space). The 19″ dimension is rigid, so the under-seat space must be at least 19″ wide. The sides and top do flex a bit, so I’m not worried about those…

Sherpa makes several lines of pet carriers. So far, I’ve looked at the “Ultimate Pet Carrier” and the “Ultimate Bag on Wheels.” The Ultimate Pet Carrier comes in Small, Medium and Large; the Ultimate Bag on Wheels only comes in Medium and Large. Both bags have built-in straps through which a seatbelt can be passed, allowing the bags to work well as car carriers.

The Small…

We bought SturdiProducts’ large-sized SturdiBag in the belief that it was just barely acceptable to most airlines. We now know that it’s too big (12Hx18Lx12W). On the bright side, its support struts are very flexible, so it does, in fact, fit under every seat we’ve encountered (and Otto the cat and Chloe the dog have both been fine — the carrier has a lot of headroom).…

PetEgo’s Jet Set Carrier, in the Small and Medium sizes, is well worth considering as an in-cabin carrier. The Small is 9.8Hx17.7Lx9W and the Medium is 10.6Hx19.7Lx9.8W — both are officially larger than the airlines’ maximum sizes, but they’re close enough that they’ll work, especially since they’re soft-sided and fairly flexible. The Large size (11.8Hx21.7Lx10.6W) is too long to work as an…

The first crate we bought was The Roof Box Company’s DogBag. The DogBag folds up (with a complicated maneuver akin to the one you may already be using on your car windshield sunscreen) and fits into a normal-sized backpack (provided by Roof Box). It has plenty of mesh netting so your dog has good ventilation and fairly good visibility. You need to supply your own floor padding (Roof Box’s Quilted Liner is thin, and…
