For their health, older dogs should wear a coat.

Over the years, the whirlwind on the leash often becomes a relaxed companion who knows exactly when it's time for the couch. What you don't immediately see from the outside: A lot changes on the inside of the dog's body – and you notice this especially in cold and wet weather.

In this article we will look at:

Why older dogs should wear a coat in rain and cold weather
Why a coat can also be useful for dogs with an undercoat
Why THEO & EMMA coats are particularly suitable for senior dogs

Why older dogs should wear a coat in rain and cold

What changes in a dog's body with age

The bodies of older dogs function somewhat differently than those of younger dogs. Typical changes include:

Thermoregulation becomes more difficult
Senior dogs often can no longer maintain their body temperature as stable as before. Their metabolism and circulation slow down, and their bodies react more sluggishly to temperature changes.
Less muscle mass = less "built-in heating"
Muscle mass decreases with age – this is well-documented in dogs and is unfortunately part of the normal aging process. Less muscle mass means less heat production during exercise.
Osteoarthritis and joint problems
Many senior dogs suffer from joint problems. Cold weather, and especially damp and cold weather, can exacerbate these conditions, making movements stiffer and causing the dog to be reluctant to get up or climb stairs.
Altered blood flow & metabolism
Older dogs are less able to "counteract" when they get cold – they shiver longer, tire more quickly and need more time to warm up again.

In short: A senior citizen gets cold faster, recovers more slowly from the cold, and is more susceptible to ailments.

How you can tell that your senior is cold

Typical signs:

Tremors or fine muscle tremors
pulled-in stomach, rounded back
drawn-up tail, “making small”
Raising paws, unsteady gait
Your dog suddenly becomes very slow outside or wants to turn around.
After the walk: it takes a long time until he seems to have "thawed out" again.

If you observe several of these points, a coat is not a luxury, but a very useful support – especially in rain, wind and single-digit temperatures.

**Why older dogs with an undercoat should wear a coat**

The classic:

"He has so much fur – he doesn't need a coat!"

This may be true for young, healthy dogs with thick coats. However, a closer look is warranted for senior dogs.

The coat changes – even in dogs with an undercoat.

The coat can change with age:

The fur becomes thinner or duller.
The shedding process is no longer as reliable.
Old undercoat stays in the fur longer, but insulates less effectively.

This means that just because a dog looks "plush" doesn't automatically mean it's well insulated outdoors – especially in cold, wet weather.

Undercoat only insulates if it stays dry.

The most important function of the undercoat is to trap air and thus insulate. However, if the fur gets really wet (rain, wet snow, splashing water from the ground), the following happens:

Water penetrates to the skin.
The insulating layer of air between the hairs is lost.
The body loses heat much faster

Studies and articles on dog clothing and fur insulation confirm that wet fur loses much of its insulating effect and heat protection decreases massively.

A waterproof or highly water-repellent coat protects the fur from becoming completely soaked – thus helping to maintain the dog's natural insulation.

Osteoarthritis, muscle loss & cold – an unfavorable combination

In many older dogs, several factors come together:

Joint changes (osteoarthritis)
less muscle
less movement and shorter rounds
poorer temperature regulation

Cold and wet weather can exacerbate joint stiffness and pain. Many veterinarians therefore recommend keeping senior dogs warm – similar to people with joint problems – to alleviate discomfort.

A coat is no substitute for therapy, but it can:

Keep large muscle groups (back, shoulders, hips) warm
to prevent the dog from "getting cold" during the walk
facilitates starting up after periods of rest

Especially for dogs that are noticeably stiffer after a walk or have difficulty getting up after lying down, it is worth discussing the topic of heat protection with the veterinarian.

Why a coat from Theo & Emma is particularly suitable for older dogs

Fit advantage: If nothing pinches or constricts, it's easier to run.

A coat can only help if your dog likes wearing it. A good fit is especially important for older dogs.

Mix & Match system
The coat is custom-made for your dog, with back length and chest circumference measured separately. This ensures a perfect fit.

did not slip
There is sufficient room for movement in the shoulder area.
does not constrict the chest

Ergonomic cut without leg straps
Especially for dogs with arthritis or sensitive hips/knees, leg straps are often uncomfortable. Our coats don't have leg straps – your dog can run, jump, and sniff freely without anything pulling or chafing.

For older dogs, this means: warmth and protection – without compromising on freedom of movement.

The right coats for every weather

You can dress your dog in layers using THEO & EMMA products:

Wet, cold & windy – COOPER raincoat

protects against rain, wet snow and splash water from the belly
keeps the undercoat dry so it can insulate
It can be wonderfully combined with a fleece sweater underneath.

Cold & dry – e.g. OSKAR winter coat

with insulating filling modeled after high-quality outdoor jackets
Ideal for dogs that get cold easily or have to stand/lie down a lot.

Transitional season & layering – Henry fleece pullover + fleece loop

On milder, but unpleasant days: just a sweater
In damp cold weather: Sweater + COOPER
For seniors who are very sensitive to the cold: a winter coat plus a fleece pullover underneath.

This allows you to flexibly respond to your dog's needs depending on the temperature, weather, and how your dog feels on any given day.

Senior-friendly handling: quick on, quick off

Older dogs often have:

less patience when getting dressed
Difficulties standing for long periods
Problems arise when legs need to be lifted high.

Theo & Emma's coats are designed so that you can put them on very easily:

simply pull the coat over your head
and pull the chest strap between the front legs and attach it to the side of the coat
So there's no need to fumble around with your legs when getting dressed.

This protects joints – and nerves, on both sides of the leash.

Visibility & safety in the dark

Many dog walks take place at dusk in autumn and winter. Reflective details on the coat and the option to attach a light (e.g., Orbiloc ) ensure that:

Your dog will be seen earlier in traffic
You will both be more easily noticed on confusing paths.

Especially for dogs that can no longer see or hear well, "being seen" is an important safety factor.
