Frequently Asked Questions

How much extra space does a dog need in a crate?

A properly fitted crate provides 2 to 4 inches of clearance above the dog's head/ears when standing, and 2 to 4 inches of extra length beyond their nose to base-of-tail measurement. Excess room encourages puppies to eliminate in a corner.

Should I buy a full-size crate for a puppy?

Yes, but only if the crate comes with an adjustable divider panel. Sizing the space to their current puppy size prevents bathroom accidents while saving you from purchasing multiple crates as they grow.
