Why Do Old Dogs Smell?

by | May 19 2022

We love our dogs, and watching them grow old can be tough. We start to notice the subtle signs of ageing, like taking an extra few minutes to get moving in the morning or lagging behind us on our daily walks. Over time, they might stop responding when we call their name, and their eyes start to get cloudy. As heartbreaking as it is for us, it’s a natural part of the ageing process There’s also a certain odour that often accompanies older dogs, which can be rather unpleasant. But what exactly causes this odour? Why do old dogs smell and is there anything you can do to avoid it?

In today’s article, we’ll explore the reasons your dog might be a bit smellier than it used to be. We’ll also outline some tactics you can use to keep your canine companion smelling good throughout their twilight years.

 

Common reasons for that ‘old dog’ smell

 

Dogs can be smelly at any age. Some love to roll in fox poo, while others stink to high heaven when they get wet. However, as they age, their coat can start to smell pretty bad and their bad breath would nearly knock you out!

A bit of a musky scent is natural and nothing to worry about, but a particularly foul odour (either from their skin, coat, or breath) can often indicate an underlying health condition that needs to be checked out as soon as possible. If your dog smells bad, it could be due to poor self-grooming or other health issues that require veterinary attention.

Here are some of the most common reasons for this distinctive “Eau d’OAP”:

 

Age-related factors

 

As dogs age, they undergo a range of physical and biological changes that can affect their overall health and well-being. One of the most noticeable changes is the impact on their sense of smell. Older dogs may experience a decline in their sense of smell due to age-related factors such as:

 

  • Reduced Olfactory Receptors: Just like humans, dogs have olfactory receptors in their noses that help them detect and process smells. As dogs age, the number of these receptors decreases, making it more challenging for them to pick up scents.

 

  • Nasal Mucosa Changes: The nasal mucosa, which filters and processes smells, can become thinner and less effective with age. This decline can make it harder for older dogs to detect and enjoy the scents around them.

 

  • Brain Changes: Age-related changes in the brain can also affect a dog’s sense of smell. The brain’s ability to process and interpret sensory information declines as dogs age, impacting their overall sensory experience.

 

Gas

 

Older pets tend to have more sensitive digestive tracts, leading to more frequent bouts of flatulence.

 

Incontinence

 

Just like humans, senior pets can often experience incontinence as they lose their ability to control their bladder. Infections, tumours, and kidney disease are all common culprits that can cause urine leakages.

 

Diabetes

 

Diabetes affects the body’s ability to produce insulin, which leads to dangerously high levels of sugar in the bloodstream. It is fairly common in older dogs and can cause their breath to smell oddly sweet (or foul in some cases).

 

Dental disease

 

Dental disease is very common, affecting up to two-thirds of dogs over the age of three, with issues often arising in a senior dog’s teeth. If the teeth are not taken care of properly, plaque and tartar will build up over time. This can lead to periodontal disease, tooth decay, and halitosis.

 

Kidney disease

 

Kidney disease also affects your dog’s breath. If the kidneys are not functioning correctly, toxins can build up in your dog’s system and cause issues in other areas of the body.

Left untreated, this can lead to kidney disease and even kidney failure. If your old dog has smellier breath than usual, make sure you take them to the vet for a checkup.

 

Allergies

 

Many dogs have skin allergies and issues that can lead to dermatitis. Scratching and biting at the itchy patches for relief can cause unpleasant smells due to fur loss, dryness, scabs, and skin infections, as these conditions can facilitate bacterial growth and further complications.

Lack of grooming

 

Dogs love to groom themselves and keep their coats clean, but this can become difficult as they age and start to experience arthritis or other mobility issues. When they are unable to groom themselves properly, excess dander and oils start to build up in the skin. Over time, this can lead to foul smells.

 

Infections

 

Many pets with allergies or other skin disorders can acquire infections and scabs on the skin. Issues with anal glands can lead to unpleasant smells and symptoms like scooting or excessive licking. Ear infections and urinary tract infections are also common in dogs, so make sure you regularly inspect your dog’s skin, coat, and ears for signs of infection.

 

What can you do to improve the smell?

 

Most dogs have a naturally musky scent due to the oils in their skin and coat. Some people love it, some people hate it, but hey — it comes with the territory! As they get older, however, pet owners can take steps to keep the smells as inoffensive as possible. These include:

 

Health checks

 

As we have seen, most foul smells are due to an underlying health condition. Taking your dog to the vet for regular checkups is the best way to ensure problems are diagnosed and treated before they become more serious.

 

Dental hygiene

 

We all know how important dental hygiene is for ourselves, but we should also take care of our dog’s teeth and gum health. Poor dental care in their early years can lead to dental disease later in life, resulting in foul-smelling breath, tooth decay, and tooth loss.

 

Baths

 

Baths can be an enjoyable part of your routine, and they will help to keep your dog smelling fresh and clean. Always use hypoallergenic products that are designed to suit their skin and coat.

Grooming

 

Treat your dog to regular visits to a dog groomer. To make sure it’s a positive experience for them, look for an experienced groomer who has a natural affinity for dogs. Your dog will love all the pampering and come out smelling lovely!

 

Diet

 

Watch their diet to see how your dog reacts to certain foods. Allergies or intolerances often get more pronounced as your dog gets older, so you may need to adapt their diet to keep them in tip-top health. Keeping bad smells at bay can sometimes be as simple as swapping to a different brand or including/excluding particular ingredients from their diet.
