If you search for some models, dog crates are not exactly the cheapest accessories available from the pet shop near me, regardless of their type. Few people agree to use second-hand things, no matter if it is for them or their pets. And the vet is one of them. The explanation is a logical one. The moment you take a particular object from someone else, you don't know the history of it. You need to find out where he used it, for how long it did, and under what circumstances. A new object represents no harm.
