Halitosis in Dogs

Halitosis is the medical term for bad odors coming from your dog’s mouth (it’s the same term used for this problem in humans, too). It can be caused by:

One of the most common causes of bad breath in dogs is periodontal disease from plaque and tartar build-up. Plaque is a biofilm that forms over the teeth when your dog beings to salivate. Over time, unless you brush his teeth regularly, plaque becomes mineralized, creating tartar. As more and more plaque and tartar build up, leading to gingivitis (gum disease).  This, in turn, can lead to tooth problems. Your pup could lose teeth due to gum inflammation. He may also start to get cavities. This can be a normal problem in most dogs, especially those that have flat faces. It can be treated by regular dental cleanings done by the vet and it can also be helped by brushing your dog’s teeth on a regular basis and using dog dental chews. However, bad breath in your fur baby could also be an indication of an underlying health issue.

Bad Breath in Dogs Caused by Health Problems

Here’s a list of some of the most common health conditions that can cause bad breath in your dog:

To cure bad breath, it may be a good idea to see your vet to start off. At the least, your fur baby will need his teeth checked, cleaned of tartar and plaque. Your dog may also have bad teeth that need to be removed. This may require your fur baby having anesthesia, but it’s best, as it will keep him comfortable and reduce his anxiety. Can you imagine just sleeping through a visit to the dentist? That’s how it will be for your canine companion. Your vet will likely also run blood tests and check your dog for any underlying health issues that could be causing your fur baby’s bad breath.

Once these causes have been ruled out, there are some steps you can take to make your dog’s breath fresher.

How to Cure Bad Dog Breath DIY

Here are some things you can do to keep your fur baby’s breath fresher, once he’s seen the vet for a dental cleaning and there are no underlying health issues.

1. Brush his teeth: this is one of the best things you can do. Many dogs won’t like this process in the beginning, but over time he’ll get used to it. You’ll need a doggie toothbrush or a child’s soft toothbrush. Don’t use one of your old toothbrushes. It’s not sanitary, and it may be too big for your dog’s mouth. Another option is to wrap gauze around your finger and use that to clean your fur baby’s teeth. Next, use a toothpaste only for dogs, which is safe for them. Never use human toothpaste, as this could make him very sick. As you begin brushing, be sure to praise him for licking the toothpaste. Just brush for a few seconds in the beginning, gradually building up to brushing his teeth for one minute. Make sure to pay attention to the inside of his teeth, too, along with the molars. It will take some time to get your pup used to getting his teeth brushed, but the payoffs are healthy teeth and gums, along with fresher doggie breath.

2. Parsley: helps with human bad breath, and it can also be good for your canine companion’s breath! Just add a bit of fresh parsley to his food or homemade dog treats, and he’ll soon have fresher breath.

3. Easy homemade dog treats for bad breath: you can also make homemade doggie treats that will help cure your fur baby’s breath issue. Dog bad breath treats are easy and economical to make. Here are some recipes to check out:
