Although a dog's breath under normal circumstances is not the sweetest smell in the world you will certainly notice when it becomes foul smelling. Bad breath is usually an indictor that something is not right with your dog's health.
Possible Causes of Bad Breath in Dogs
Broken, Decayed or Abscessed tooth.
Periodontal Disease
Periodontitis (inflammation of the tissue surrounding the teeth)
Bone or foreign body stuck between the teeth
Gastrointestinal disease including cancers and obstructions
Sinus infections
Kidney Disease
Mouth tumors
Firstly, ask yourself if there are any other symptoms associated with the bad breath.
Does your dog seem to be in pain around the mouth area? Is there a reluctance to eat? Does your dog try to eat but drops the food once it gets into the mouth? Does your dog run to the food bowl eagerly then cannot eat. Is your dog pawing at the mouth? Is your dog drooling?
These could be signs of a bad, broken or abscessed tooth or gum disease. If possible, check your dog's mouth for foreign bodies such as splinters of bones lodged between the teeth. Check to see if the gums look normal and that there are no signs of swelling or bleeding. An abscessed or damaged tooth may not be noticeable to you so if in doubt get your vet to check your dog's mouth.
Sometimes the food (or garbage) a dog eats can affect it's breath but usually this is not long lasting. After a couple of hours the food has passed through the stomach and into the intestines.
Some underlying conditions that cause canine bad breath can only be successfully diagnosed by your veterinarian.
Avoid expensive dental bills by caring for your dog's teeth. Remember the old adage that prevention is better than cure.
Dental disease is one of the most common symptoms of bad breath in dogs. Tartar build up caused by plaque should be avoided by either cleaning your dog's teeth yourself or having an annual scaling by your vet. There are specially formulated toothpastes and specially designed toothbrushes for dogs.
Brush your dog's teeth daily. You may have some difficulties when you first begin to do this but many dogs end up enjoying the procedure. You may wish to use a regular dog toothbrush or a finger brush. A finger brush is a rubber cap that you place over your finger. It has soft rubber bristles and is useful for getting into hard to reach areas. Many dogs who won't let you brush with a toothbrush will allow you to put your finger in their mouth using the finger brush.
Never use human toothpaste on your dog. Your dog will invariably swallow whatever you clean his teeth with. There are many flavored dog toothpastes on the market which are designed to be swallowed. Finding the flavor your dog likes will make brushing all the easier. Toothpastes come in many flavors including beef, chicken, malt, vanilla and many more.
