Frequently Asked Questions
Do insulated liners make the kennel too hot in summer?
Not if you pick a kennel with a removable liner, ventilated porch or PVC curtain and raised floor. On warm days remove the liner or open the curtain to allow airflow; the raised floor helps cooler air circulate under the house.
Can I wash the insulated liners?
Many designs in this roundup include removable fabric covers or liners that can be machine-washed or spot-cleaned — check the product description. Removing the liner also makes seasonal storage and swapping simpler.
How do I pick the right size?
Measure your dog lying down and add space to stand, turn and stretch. Compare those dimensions to the kennel’s internal measurements rather than external, since customers sometimes report size surprises.
