James Lomax, landscape and garden care buyer for Masters Home Improvement, said your pet's comfort should be the number one consideration when choosing a kennel.
"The size of the kennel must allow your pet to stand in a natural position, turn around easily and lie down comfortably," he said.
"Measure your pet's height, width and length and bring these measurements with you when shopping for a new kennel."
City Farmers' Rachael Jennings said insulation was also vital.
"It's important to check if the kennel can keep your dog cool in summer but warm in winter," she said. "Not all kennels are insulated and it's an important factor."
Ms Jenning said there were simple things you could do to further protect your dog from weather.
"If your kennel is exposed to the elements, a door flap will help protect your dog from wind and rain," she said.
"Similarly, if the kennel is not raised, consider adding a flatbed mattress to keep old bones from getting cold."
Once you've found the perfect kennel, where you position it is also important.
"Like all good real estate, location is the key," said Kath Bafile, of Better Pets and Gardens.
"Place the kennel in a position where the dog can see the back door and everything that is going on in the backyard. They hate to miss out on what is going on around them."
