What is the best dog cage size?

I agree with the previous post but I would also like to add that it depends on what you are using the cage for. If you are using it to potty train then you will definately want it to be as small as is comfortable for the dog. They don't like going to the bathroom where they sleep, so you can potty train a puppy pretty quickly this way. If you are using it for travel and have no space restrictions then you would want to make it large enough to accomodate a comfy bed and food and water bowls. Hope this helps!

When I get dog cages, I always make sure that it's big enough for them to stand up, and turn around in. I don't know about your dog, but all the ones I've ever had want to do that thing where they kind of circle around and then lay down. Since it seems to be a natural habit of most dogs, I always figured that I should cater to that natural instinct they have.
