Other Causes and Treatments
There are a variety of health conditions
in which halitosis is one sign. This includes:
• Respiratory infection
• Gastrointestinal conditions
• Sinusitis (infection of the nasal cavities)
• Tonsillitis (infection of the tonsils)
• Foreign body stuck in the teeth or in the throat
If your Chihuahua has unexplained bad breath that is not fixed with brushing, dental treats
and chew toys, it is important to bring the puppy or dog to the vet for a complete checkup to narrow down the possible causes, since some can be quite serious.
If a dog eats feces (his own or that of another dog) this is referred to as coprophagia and it can cause many issues. Worms and bad breath are just two of the possible consequences. It is often a sign of malnutrition, even if that dogs eats plenty of his own food. The most common reason for this is a diet that is bulked up with fillers yet has very little nutritional value. Changing to a quality dog food often resolves this.
Owners are encouraged to watch their dog at all times to prevent the ingestion of feces. When on leash, your dog should be close to you. In fact, for proper heeling, he should be directly to your left side. Allowing a dog to lead the way when walking only opens the possibility for him to ingest weeds, flowers, bugs and feces and he will have the resulting bad breath that follows.
When a Chihuahua puppy or dog has breath that has a fishy smell (and they have not just ingested fish) this can point to an infection. It may not be related to the gums, but may be in the throat or other areas of the mouth.
Fruity/ Overly sweet odor-
When there are very high levels of sugar in the bloodstream it can cause this sort of odor on the breath and is an indication that the dog may have diabetes. Other signs are drinking more than normal (which leads to more frequent urination), larger than normal appetite and unexplained weight loss.
When the odor of urine emanates from the mouth, this can point to kidney disease.
Home Remedies to Fix a Chihuahua's Bad Breath Problem
1) Fresh Herbs
Encouraging a dog to chew on fresh peppermint leaves may freshen the breath; though without proper dental care it will be temporary. Some owners have found luck with fresh parsley leaves as well. Both of these herbs also have some small antibacterial properties that may lend to fixing the problem.
Fresh, concentrated lemon juice may work. Be sure to only add a few drops (2 to 3) to one full bowl
of fresh water. If to much is added, a dog may refuse to drink his water. It is thought that the high level of citric acid works to kill bacteria in the mouth.
