With all of its great features, this heavy duty dog cage is not without its faults, and the main issue is that it's difficult to put together. Unlike metal dog crates like MidWest iCrate, the MIM Safe Variocage dog travel cage needs to be assembled from scratch which takes time, effort and understanding. These dog crates come in 14 changeable sizes to fit most dogs, and they come in four different models. This gives you a better chance at finding a suitable fit for your vehicle or one that will pass the guidelines for the method of transportation that you will be taking.
The Petmate Sky Kennel is a great example of your standard hard-sided kennel. With good ventilation, the ability to tie it down in a car, and solid construction, this crate is a fantastic choice for medium sized dogs. The vents on the side are covered in a thicker metal, and allow for more air to come in with less chance of escape. The Sky Kennel is also recommended for travel on planes, either with you or in a luggage area.
