Fox terriers
These bundles of energy bring plenty of joy to Aussie families — and definitely enjoy their winter outings. However, it's wise to be aware of how they may be coping when the temperature drops, even if it doesn't feel like a massive change to you.
'Small dogs have a higher surface-area-to-volume ratio, which equates to more skin exposed to the environment compared to their size,' says Dr Morris.
'This means they get colder faster than larger dogs. They often feel minor changes in temperature more acutely.'
Look for: Something cute and colourful that won't inhibit any of that excitability.
Try: Protect your furry friend from the elements in style with the DGG Puffer Dog Jacket in classic Navy. For fashionable warmth, consider the delightful DGG Designer Warmie Dog Jumper, available in both the endearing My Love and the charming Sparkley Snuggles designs.
Kelpies
Lean and muscular, these beloved working dogs do have two very effective coats — a dense inner one as well as an outer layer that prevents rain from getting through. But because they're often housed outside in kennels, they can still be susceptible when the barometer dips dramatically at bedtime, says Dr Morris. 'Many parts of rural Australia experience very cold temperatures overnight, even if it is comfortable and warm during the day.'
Look for: Smart options for daytime exploring or snoozing in the kennel.
Try: Prepare your adventurous dog for any weather with the durable Ruff n Rugged Mortech Rambler Dog Coat in striking Purple, or choose the timeless appeal of the Ruff n Rugged Corduroy Dog Jacket in sophisticated Steel Grey. For ultimate warmth and comfort, the Ruff n Rugged The Woolly Dog Jumper in classic Dark Green is an ideal choice for chilly days.
Labradors
Perhaps the definitive Aussie pet pooch, this extremely popular breed is unfortunately prone to joint conditions like arthritis and hip dysplasia as they age, says Dr Morris. When the winter chill sets in, this can exacerbate the discomfort that comes with those conditions, so putting them in a coat or jumper is a good call. 'Cold weather stiffens the joints, making them harder to move and more painful,' explains Dr Morris. 'Keeping joints warm helps them move more freely.'
Look for: A great coat for daily exercise, or a snug jumper to warm the joints when indoors.
Try: Equip your dog for any adventure with the practical Ruff n Rugged Utility Dog Coat in classic Navy or the sleek Ruff N Rugged Trail Blazer Coat in Black, both designed for durability. For a touch of cozy style and a sense of protection, the DGG Designer Warmie Dog Jumper in Security offers comfortable warmth.
Dachshunds
Who doesn't go all mushy inside when you spy an adorable dachshund scooting around? These playful pups are another popular pet, but their smooth coat and short stature mean they can be exposed to the chill more than their taller counterparts.
'Hot air rises and cold air sinks, and ground temperature is cooler than air temperature,' says Dr Morris. 'Dogs with short legs such as dachshunds, are closer to the ground so possibly experience cooler temperatures than their long-legged friends.'
Look for: Longer designs or stretchy fabrics to keep them covered — and maybe a beanie.
Try: Get your dog ready for a bold statement with the DGG Printed Warmie Dog Jumper in Fierce, or opt for vibrant protection with the Ruff n Rugged Utility Dog Coat in striking Red. Complete a coordinated look by pairing the adorable DGG Beanie Dog Hat in Melon/Raspberry with the matching and cozy DGG Chunky Knit Dog Jumper.
As well as rugging up your four-legged pals with some super-cute garments, when going out, don't forget to make your home a warming environment also. 'Let them sleep inside, especially at night,' tips Dr Morris. 'And [grab] a bed, blanket, pet-safe hot-water bottles, heated mats and blankets.'
There are plenty of great ways to ensure they're not feeling the freeze — and don't forget the cuddles.
Look for: Cosy items to give them somewhere to snuggle (apart from your lap).
Try: For a cozy and supportive rest, consider the Lexi & Me Bolster Dog Bed Green Quilt in Small/Medium, offering comfort and style. Alternatively, provide your pet with superior joint support and luxurious relaxation on the Buddy & Belle Orthopaedic Lounge Bed in elegant Pearl Blue, which can be perfectly complemented by the soft and versatile Buddy & Belle Reversible Plush Blanket in matching Pearl Blue.
