What Causes Bad Dog Breath? 

Bad Breath Causes in Dogs
There are many causes for bad breath in dogs.

In the medical world of dogs, bad breath is officially known as Halitosis. But before we even consider what nutrition is best for your dog’s bad breath, it is important to understand what it is that’s causing it. Because there are a number of medical conditions that could be behind your pup’s smelly breath, we want to take a deeper look to make sure that something may not need medical attention before changing foods.

If your pup exhibits any health-related issues, we always recommend that you see your vet immediately.  They will be best equipped to diagnose any serious problems that may require further analysis.  There are several factors that can cause Halitosis in dogs, and if your beloved pooch is suffering then it is likely to be one of the following reasons: 

Poor Oral Hygiene

Just like us humans, if your dog’s teeth aren’t brushed regularly, then his breath is going to start getting smelly simply due to a buildup of plaque and tartar, it really isn’t rocket science! However, many dog owners just think that smelly dog breath is just part of the ride, but not only does it not have to be, bad breath is often a signal that there may be an underlying cause and further health problems that you need to consider. Not only does plaque and tartar cause smelly breath, it also begins to break down his gums which exposes even more room for the pesky bacteria to develop. This will quickly cause inflamed gums, cavities, infections, and tooth loss. 

Periodontal Diseases

Periodontal disease is a collective term to describe the infections in the structures surrounding his teeth, these structures include his gums, his periodontal ligament and the ridge of bone around his jaw that contains his teeth sockets. In dogs there are four stages of periodontal disease, first it starts with inflamed gums and stained teeth, which is known as Gingivitis. Eventually he will reach the advanced stages whereby more than 50% of his connective attachment tissues and gums become rotten, where the roots of his teeth will begin to show. Early signs of periodontal disease are bleeding gums (or finding blood on his chew toys), bad breath and stained teeth.

Unpleasant Habits

Some dogs like to rummage through the garbage and eat rotten leftovers and some like to eat rotten animal carcasses or bones when out on walkies. Some dogs like to eat poop, some are fussy and will only eat fox or cat poop (geese and cow poop are my boy’s personal favorites!), whereas some dogs will eat all kinds of poop, and some dogs will even eat their own! Whichever delightful delicacy your pooch favors, it is probably going to make his breath stink! Fear not, your dog is not alone, and research has found that 24% of dogs will try this doggy delicacy at least once in their lifetime, but only 16% of them will go onto being serial poop munchers.

Kidney & Liver Disease

Dogs don’t just eat poop, sometimes they also drink urine. So, if your dog’s breath smells like urine then it is a sign that he might have kidney disease. Kidney disease can often be a symptom of another larger problem, so if you notice that he is drinking pee or his breath smells like pee, then take him to the Veterinarian immediately. In addition to smelly breath, if your dog’s gum are slightly yellow in color, and he is vomiting, then this could also be a sign of liver disease, which is equally as devastating and could also be a sign of something more sinister.

Diabetes

If your dog’s breath smells like sweets or has a fruity aroma, then whilst it might smell appealing, it can actually be a sign that he has Diabetes. While this is a serious condition, it is something that can be easily managed once diagnosed and medicated. So, if you notice a sweet smell, or your dog is drinking vast amounts of water and urinating a lot, then get a Veterinary appointment booked for him immediately. 

Breeds Prone to Bad Breath

Greyhound with Bad Breath
Greyhounds are one of many breeds that suffer from chronic bad breath.

Certain dogs are more prone to periodontal diseases and bad breath more so than others, so this is another important factor to consider when it comes to his dental hygiene. However, it is important to note here that just because your dog doesn’t fall into any of the below categories does not mean that he will be  free from the perils of bad breath and associated diseases. 

Small dog breeds, particularly those who are considered to be toy dogs, are particularly prone to periodontal diseases. Their little mouths are a lot smaller than bigger dogs, but they still have to fit in the same amount of teeth, so they become a lot more compact. Not only does this cause spatial issues, but they are also more likely to suffer from a buildup of plaque and tartar, gum recession, loss of teeth, and of course, bad breath. 

Dogs with narrow muzzles, such as the Greyhound or the whippet to name a couple, are also prone to a variety of dental diseases, simply because of the lack of space in their mouth. It is becoming increasingly common for dogs with narrow muzzles to be born with missing teeth too. So these dog breeds need that extra bit of dental attention.


Top Foods For Bad Breath

Top Dog Foods For Stinky Breath
There are several foods made specifically to remedy bad breath.

We have scoured the market for the best dry dog food which all contribute towards having healthier and cleaner teeth, which will noticeably freshen his breath. There are several choices here dependant on the current health of your dog’s teeth. For those dogs who are younger who have not quite reached the stage of Gingivitis or periodontal disease stages, then choosing a kibble that is high in fiber will help to break down the built-up tartar and plaque, and ultimately freshen his breath. If your dog is medium-sized or above, then there is also the option to feed him kibble that is larger in size, which encourages him to chew and crunch more, which again helps to break down and remove that bacteria on his teeth and gums, but of course this is not an option for smaller breeds. 

There are also more advanced options for those who have been diagnosed with periodontal diseases, and whose Veterinarian has prescribed a specific dental care diet. We have listed three of these kibbles at the end of our list, but be aware that to order these you need to submit your Veterinarian prescription for your order to be approved.

These diets are designed by Veterinarians and Nutritionists whose ingredients and kibble design are aimed at dogs whose teeth are in poor condition, who will eat these alongside undergoing professional cleans and potential surgery. Again, these recipes will noticeably freshen his breath.  So, in no particular order, here are our top dry dog food kibbles that are the very best on the market designed specifically for his bad breath!

Final Thoughts 

So, the ‘tooth’ of the matter is that you need to take care of his oral hygiene, because not only will this freshen up his breath, but it will also decrease his chances of periodontal diseases, and other more serious health concerns. Whilst many people think that dogs mouths are much cleaner than us humans, it does not mean that they are self-cleaning, and their mouths still need a bit of extra help! 

Bad breath can easily be freshened up with the right high-quality dry dog food, and whilst you will still need to brush his teeth and give him daily dental chews, the wrong dog food can still make his breath smelly even after all of the other steps. By choosing one of our recommendations above, not only will you be giving him one of the best quality natural foods that will service all of his other needs, such as lean protein and antioxidant superfoods, but you know that it is going to clean up that mouth of his and turn his teeth into pearly whites once again. Stick with one of our picks and you are sure to find the best bad breath dog food for your pup!
