Made in the USA! This large dog kennel is perfect for your larger breed of dogs or for more space when kenneling at home. It can be stacked or coupled for transport in a boarding or vet clinic setting. Vent hole patterns differ among styles, please see photos displayed for the standard (1 3/8″ hole size), with two finger holes in the back. (Please note that the double door versions will add 1 1/2″ to the dimension.)
