Buying a wheeled carrier is the sort of thing that you would only ever end up doing if you needed to take your pet to the hospital, and there is a pretty good chance that you would want to prioritize durability if you are buying one that is brand new. The truth of the situation is that durability is something that will always be a given when it comes to wheeled carriers and the like. This is because of the fact that they are built for heavy animals, so there is no chance that you would ever end up purchasing something or the other that would not be durable enough for your purposes.
The fact of the matter is that while all wheeled carriers that possess a 3pt hitch attachment are going to be sturdy in a lot of ways, not all of them will be speedy. You will be stuck dragging your pet using wheels that are not optimized at all, and this will make the work that you put into taking them to the vet a lot more strenuous than it needs to be.
Try to take the wheeled carrier for a test run before you purchase it. This will put into perspective how effective and useful it would actually be for you. Prioritizing a wheeled carrier that is practical in every way is the right way to go about looking for the right one, and you will be glad that you did your due diligence when you end up having such an easy time transporting your pet. Speedy carriers can also offer a smoother ride to your pet which is another thing that it will appreciate all in all.
