The Petego Comfort Wagon is a very thoughtfully designed and versatile dog transport system - it's a bike trailer, a stroller (if you buy the stroller accessory) and, because the wheels and trailer drawbar are so quickly fitted and removed, also a temporary place for a dog to stay when out and about, including in your vehicle boot, if it's big enough.

It has zip doors on all four sides, with the front and rear panels including snap clips to make a window, not a door - they prevent the dog from using its nose to open the zip to floor level. There's also a sunroof opening - you use this when assembling the Comfort Wagon - which also provides a good opportunity to keep in eye contact with your dog. It's light and airy, with all window panels made from a claw-proof polyester mesh - there are even offside and nearside rear mesh panels so the dog can see out when lying down.

The base is made from thermoformed plastic, with a removable plug so it's more easily cleaned and rinsed out. The frame is made of aluminium tube, and it's surprisingly strong - it can hold 75kg, not that we'd recommend that you try pulling such a weight on a bike!

It's folder height is only 25cm - it's easily folded, for transport in a car if needed, or for home storage. The wheels click into place - push the rubber covered catch in the centre to fit and remove.

The basic kit includes the Comfort Wagon, a bike towing bar, and a bike connection. The stroller kit is an accessory.

This is the Medium size.

This is Italian design so, as well as the clever functionality and engineering, note the overall design - the juxtaposition of colours, the shape of the mesh and solid panels, the fun elements including front and rear reflective 'lights'!

Other features and specifications:

• Spring suspension system.
• There is no foot brake, but there are Velcro straps to pass around one or both wheel rims; these lock the wheels. The previous model, Sport Wagon, had brakes but no suspension system; there's no doubt that the spring suspension is much the better of these two options.
• You'll need a bike pump to inflate the tyres and keep them at the correct pressure.
• Dimensions when open: 86cm long x 46cm wide x 56cm high, without the wheels. Add the wheels, and it's 15cm higher, so tops out at 71cm.
• Dimensions when closed: 86cm long x 46cm wide x 25cm high.

In summary, smart and practical, and - we think - very good value for the money.
