FAQ’s & Buyer’s Guide
How does halitosis in dogs start?
Several causes throughout the body can result in bad breath for dogs. Gastrointestinal problems, from the minor like an imbalance of healthy and unhealthy bacteria to the major such as intestinal blockage, can create conditions for smelly breath. Dental issues ranging from broken teeth to periodontal disease all usually involve the buildup of bacteria, leading to odor, which are the most common causes of bad breath.
In what ways does diet influence breath?
Certain foods combine with a dog’s natural body chemistry for an unpleasant breath smell, or they could have picked up an odor from something they nudged their nose and mouth into during explorations outside. Chronic bad breath can also be caused by food that doesn’t address your dog’s digestive health. Once you and your veterinarian find the right food, it can also provide the solution.
Is dental health that important?
A dog uses its mouth for other things besides eating. Dogs use their mouths to explore their world by licking, chewing, and tasting things not meant for them. With infected gums, broken teeth, and periodontal disease, using their mouth causes a lot of pain, and it likely won’t take long until eating isn’t worth it, which will quickly lead to other health problems. Dogs that can’t do what they usually do with their mouths can become listless and depressed.
How does dog food actively remove tartar?
Dog food in hard kibble form can actively rub against the tooth’s outer surface during chewing and naturally remove tartar. Fortunately this prevents the buildup of bacteria within tartar deposits which can also lodge beneath the gumline. Various dog food recipes take advantage of this by utilizing certain textures that effectively scrape away the tartar and specific size and shape of kibble to keep them chewing long.
Is dry dog food the only way to reduce plaque buildup?
Some veterinarians advise parents of dogs with dental problems to steer clear of wet food as it may get under the gumline easier and cause bacteria buildup. However, some canned food formulas exist in the market now that have textures less likely to lodge between teeth and nutrients that discourage plaque.
What should I do in conjunction with a healthy diet to promote good dental health for my dog?
If your dog will allow you to brush his/her teeth, this is a fantastic way to prevent painful and debilitating dental issues. Just as the bristles reach between teeth and into the gumline for humans, they can rid dogs’ mouths of hard-to-reach plaque. In addition, having a dental checkup and teeth cleaning with your veterinarian will identify any red flag health issues and address them as early as possible.
Should I take my dog to the veterinarian for chronic bad breath?
Persistent bad breath is often the first sign of a more serious health problem. Your dog may have allergies, anxiety, dental, or gastrointestinal difficulties not easily observed from the outside. A veterinarian’s experienced eyes will likely be able to identify the problem quickly, or they may determine a need for internal testing that will save lots of pain and cost later.
Is bad dog breath a symptom of diabetes?
If you smell a sweet, fruity smell from your dog’s mouth, there is a good chance your dog is diabetic, and you’ll need to make an appointment with your veterinarian immediately. Diabetic dogs have trouble breaking down glucose, so the buildup of ketones in their system gives off a fruity smell.
Do dog foods containing fish cause bad breath?
Being a lean protein, fish is a clean ingredient in dog food. Particularly after cooking and producing the finished meal, fishy smells are not likely to linger within dog food packages or cans. If the food itself triggers an allergy in your dog or is otherwise a wrong fit, bad breath might be a secondary result.
Isn’t bad breath normal for dogs?
Let’s be honest—none of us smell like a meadow all the time. We love our dogs no matter what and sloppy dog kisses are well worth a little doggy smell. However, dog breath should typically be only a mild, normal mouth/saliva smell. An underlying pungent smell could be nothing more than particularly smelly food, but if it doesn’t pass, it’s not something you should igno
How are gas/bloating and bad breath related?
The teeth break up the food and pass it down the esophagus to the stomach and intestines for breakdown and absorption of the nutrients and then discarding the waste. Interruptions or difficulties in this process often result in a gassy, bloated belly, which may or may not coincide with smelly breath. Digestive issues often cause bad breath, so look for these signs and consider trying different food.
How are dogs equipped to keep their mouths clean?
Dog saliva is a powerful tool in keeping dental problems away and mouths and breath clean. At the chemical level, dog saliva contains compounds that naturally attack harmful bacteria, which is why dogs habitually lick at wounds and itchy spots, and this process encourages healing.
My dog licks or eats anything he finds. Can I really solve his bad breath problem?
In a word, yes. Your dog can chew, lick, or otherwise investigate lots of foul and disgusting things it finds on the ground before you can stop them and still come out smelling fresh and clean. Dog saliva is more powerful than ours at keeping things sterile. If it persists, bad breath probably has to do with an internal problem.
If I give my dog breath-freshening chews, do I still have to change his diet?
Dental chews can take care of minor smells coming from dog breath. Chews formulated with compounds that address tartar buildup can prevent dental problems that lead to chronic bad breath. Sometimes this is all it takes to keep your dog’s mouth healthy, but if his/her diet is not meeting nutritional needs, then health problems will crop up sooner or later.
Is bad breath something that mainly happens with senior dogs?
Having used their teeth for many more years than younger dogs, senior dogs are prone to broken or infected teeth. Their systems may have trouble retaining calcium and other minerals that keep teeth strong. With care and attention, though, senior dogs can enjoy dental health and pain-free chewing and eating. Annual teeth cleaning at your veterinarian’s office goes a long way!
Is there a breath-freshening, dental-health food that will be easy on my dog’s sensitive stomach?
You’re in luck! The expansive market of dog food and products offers many foods that address one issue or several at once. Several foods contain beneficial ingredients that work to fight dental problems and keep components simple enough that allergy-prone dogs should digest them with no problem.
Does the size of kibble matter in helping to fight plaque?
Size of individual pieces of dog food does play a role in the way dogs chew and scrape excess plaque from their teeth. Larger pieces mean longer chewing time so that each piece can be more effective in agitating plaque and washing it away. Keep your dog’s size and eating tendencies in mind, though, when choosing the right food. You don’t want a kibble so large they won’t eat it or so small they’ll swallow without chewing
What are the more serious conditions bad breath can indicate?
Digestive problems are one thing, but blockages in the intestine can be especially scary. Blockages that cannot be resolved naturally may require surgery to fix. When kidney function breaks down, bad breath can result from waste products not being removed from the body as they normally would be.
Are certain dog breeds more prone to bad breath?
According to polls of dog owners, it seems that dogs with the worst breath, and those who frequently have to go to the veterinarian for dental problems, tend to be smaller breeds with lots of fur around their facial areas. This problem may result from smaller teeth have smaller spaces between them and smaller pockets in the gum areas for bacteria to hide and multiply. Furrier faces may also unwittingly collect more food particles that may go unnoticed/uncleaned.
How do I brush my dog’s teeth?
Get your dog used to consistently opening their mouth for you while training, and reward them with praise. Purchase a dog toothbrush, which is smaller to get into smaller mouth crevices and features softer bristles to get in the gumline.
What You Should Look For In Choosing Dog Food That Will Keep Breath Fresh
Kibble Size
Whether you choose a prescription food with patented technology kibble shape and consistency or just the right size and crunch, the potential for kibble to shake plaque loose from teeth goes a long way in keeping your pet’s breath fresh. The crunching action creates friction that doesn’t erode the protective enamel prematurely and loosens plaque buildup. For large breeds, many brands now have large kibble that requires prolonged chewing. There are smaller bites for smaller dogs too. Whatever the size of the dog and kibble, they need to match so that the kibble is chewed and not swallowed whole.
Ingredients That Promote Dental Health
Calcium – directly nourishes bones and teeth and strengthens tooth enamel
Glucosamine and chondroitin – promote strong tooth enamel structure
Fatty acids – lipids are essential to the health of many tissues, and for gums in particular they specifically inhibit the inflammation response in the gums and prevent the development of periodontal disease
Antioxidants – among other benefits, these fight off damage from free radicals to tissues like gums, helping to prevent gum inflammation and periodontal disease
Ingredients That Help Digestion
Prebiotics – these nourish the helpful bacteria lining the gastrointestinal tract
Probiotics – one of the forms of healthy bacteria which help with the breakdown of foods and the elimination of harmful bacteria, probiotics aid in keeping a dog’s mouth clean and beneficial by displacing harmful bacteria between teeth and in gumline spaces
Great Taste
Your dog has to like and eat the food for it to work. With quality ingredients that nourish the whole body and bring a hearty taste that your dog will look forward to, the right dog food will be able to accomplish a full belly, a healthy body, and fresh, clean breath.
