This Crate Size Chart is a general recommendation!
Determine crate size by dogs weight and height as well as breed.
Measure dog from floor to top of head sitting and standing.
Individual dogs within a breed or mixed breed may vary in size.
Each dog should individually be measured for the correct crate size. Your dog should have about 2" - 4" of head room when sitting or standing up and be able to turn around and lie down comfortable.
For puppies choose the proper size for his future adult size. Please consult a pet professional for additional guidance.
