Health conditions that make elderly dogs smell bad

Many dog owners know the less pleasant side of owning a dog includes their tendency to get dirty or have odd smells from time to time, but a constantly bad odour, especially in elderly dogs, is not normal and should not be ignored. Senior dogs often have distinctive smells that can be the first sign of an underlying health problem.

This comprehensive article sheds light on common health conditions and issues that can cause your elderly dog to smell bad and offers guidance on recognising and managing these concerns to ensure your pet's comfort and wellbeing.

1. Diabetes

Dogs of any age can develop diabetes, but older dogs are at higher risk. When diabetes is not well managed, it can cause a metabolic condition called ketosis where fat is broken down for energy. This results in a sweet, fruity, and sometimes unpleasant breath smell often compared to rotting fruit. If you notice this distinctive breath odour, a veterinary check-up is crucial to diagnose and manage the disease properly.

2. Kidney Disease

Kidney problems are common in senior dogs and can lead to an ammonia-like or foul breath smell due to toxins accumulating in the body. This systemic illness affects overall health and can cause your dog to smell generally unpleasant due to grooming habits transferring odour from urine or skin infections. Early veterinary intervention and management can improve your dog's quality of life.

3. Poor Dental Health

Dental disease, including gum infection, tartar, and tooth decay, is a frequent cause of bad breath and overall unpleasant odour in older dogs. Painful teeth can make eating difficult and reduce your dog's quality of life. Regular dental checks and professional cleaning or extractions performed by a vet can greatly improve breath and general hygiene.

4. Impacted or Infected Anal Glands

Anal gland problems are common in older dogs and produce a strong, fishy odour, often noticeable around your dog's hindquarters. Dogs with impactions may scoot on the ground or strain when passing stools due to discomfort. Expressing the glands, either by your vet or trained groomer, can provide relief and reduce unpleasant smells.

5. Urinary Incontinence

Older dogs may suffer from weakening of bladder muscles leading to urinary incontinence. This can cause urine leakage or dribbling, often unnoticed until your dog has a persistent smell of urine. Maintaining hygiene, frequent cleaning of soiled areas, and a consultation with your vet can help manage incontinence and reduce smells.

6. Skin Conditions

Allergies, dermatitis, parasite infestations like fleas or mites, and bacterial or fungal infections frequently affect aging dogs, making their skin oily, inflamed, or infected and producing a musty or foul smell. Senior dogs may also be less able to groom themselves effectively. Veterinary diagnosis and appropriate treatment for skin conditions are essential to address these odours.

7. Poor Grooming

As dogs age, they may groom less due to reduced mobility or discomfort. Less frequent brushing and bathing can result in an unwashed, unpleasant smell. Providing regular grooming sessions, baths suited for sensitive senior skin, and assistance with grooming tasks can help keep your elderly dog clean and smelling fresh.

When to See Your Vet

Persistent or sudden bad odour in an elderly dog is often a sign of an underlying health concern. A thorough veterinary examination can identify any medical issues, including infections, metabolic conditions, or dental disease, helping you devise an effective treatment plan. Early intervention not only improves your dog's comfort but can prevent more serious complications.

Conclusion

Unpleasant smells from elderly dogs often signal health or hygiene issues that need attention. By understanding these common causes — from diabetes and kidney disease to dental and skin problems — you can better recognise when your dog needs help. Regular veterinary check-ups, attentive grooming, and prompt treatment for medical problems are key to keeping your senior dog comfortable, healthy, and smelling their best.
