Why does my dog’s breath smell putrid?

Answered by Randy McIntyre

Dogs can have bad breath for various reasons, but one common cause is dental disease. Dental disease in dogs occurs when there is an overgrowth of bacteria in the mouth, forming a sticky film called plaque. Plaque can accumulate on the teeth and along the gumline, leading to the development of tartar.

Tartar, also known as dental calculus, is a hard, yellowish substance that forms when plaque is not properly removed from the teeth. As tartar builds up, it can irritate the gums and cause inflammation, a condition known as gingivitis. The inflamed gums can appear red, swollen, and may bleed easily.

The presence of tartar and gingivitis can contribute to the foul odor of your dog’s breath. The bacteria in the mouth produce volatile sulfur compounds, which are responsible for the putrid smell. These compounds can be particularly potent when there is a significant accumulation of tartar and bacterial overgrowth.

If left untreated, dental disease can progress further, leading to more serious issues such as periodontal disease. In advanced stages, teeth may become loose and even fall out, causing pain and discomfort for your dog.

In addition to dental disease, there are other factors that can contribute to bad breath in dogs. These can include:

1. Diet: Certain foods, especially those high in protein, can cause a strong odor in a dog’s breath. Additionally, if your dog has been eating something foul or has ingested something they shouldn’t have, it can result in bad breath.

2. Poor oral hygiene: Just like humans, dogs need regular dental care to maintain good oral health. If their teeth are not brushed regularly or if they do not receive dental cleanings from a veterinarian, plaque and tartar can accumulate, leading to bad breath.

3. Medical conditions: Some medical conditions, such as gastrointestinal issues, liver disease, or kidney disease, can cause bad breath in dogs. If your dog’s breath consistently smells foul despite good oral hygiene, it’s important to consult with a veterinarian to rule out any underlying health problems.

To help improve your dog’s breath, it’s important to address the underlying cause. Here are some steps you can take:

1. Regular dental care: Brushing your dog’s teeth regularly, ideally daily or at least several times a week, can help prevent the buildup of plaque and tartar. Use a toothbrush and toothpaste specifically designed for dogs, and introduce toothbrushing gradually to make it a positive experience for your dog.

2. Professional dental cleanings: Regular dental cleanings performed by a veterinarian are crucial for maintaining your dog’s oral health. These cleanings involve scaling the teeth to remove tartar and plaque, as well as polishing the teeth to discourage further plaque buildup.

3. Dental chews and toys: Providing your dog with appropriate dental chews and toys can help promote good oral hygiene. Chewing on these items can help remove plaque and tartar from the teeth and gumline. Look for products that have received the Veterinary Oral Health Council (VOHC) seal of approval.

4. Balanced diet: Feeding your dog a balanced and high-quality diet can contribute to overall oral health. Some specialized dental diets are designed to help reduce plaque and tartar buildup.

5. Regular veterinary check-ups: Including a dental examination as part of your dog’s routine veterinary check-ups can help identify any dental issues early on and prevent them from progressing into more serious conditions.

It’s important to remember that addressing bad breath in dogs goes beyond masking the odor with breath fresheners or dental sprays. These products may provide temporary relief but do not address the underlying cause of the problem. Consulting with a veterinarian is essential for a proper diagnosis and treatment plan tailored to your dog’s specific needs.

In my personal experience, I had a dog who developed bad breath due to dental disease. It started with a noticeable odor, and upon closer inspection, I could see the accumulation of tartar on her teeth. I immediately scheduled a dental cleaning with my veterinarian and implemented a daily toothbrushing routine. After the dental cleaning and regular oral care, her breath significantly improved, and her overall oral health improved as well. It is crucial to be proactive in addressing dental issues to ensure your dog’s comfort and well-being.
