Just type crate into the search box to see hundreds of messages about why we all love them so much! I tried 4 days with a new puppy and no crate. When the crate arrived from ebay (cheap as chips and great quality - pm me if you want details) our life was transformed.
Pup loved it from day 1 and is so happy and content in there - she will settle in there even when she has worked herself into a frenzy when she is overtired.
Its definitely worth doing. Puppy teeth are VERY sharp and Purdey has ripped holes in the little canvas puppy crate we use in the car. Would definitely recommend a wire one, as they are stronger, and allow much better ventilation etc.
Good luck - and cant wait to see pics of your pup!!
