Bad “Dog” Breath
Let’s face it, we don’t like the smell of most any dog’s breath- however, specific smells can be tell-tale signs of medical issues lying beneath the surface.
Types of bad breath to be looking for according to http://pets.webmd.com/dogs/guide/bad-breath-dogs:
Unusually sweet or fruity breath could indicate diabetes, particularly if your dog has been drinking and urinating more frequently than usual.
Breath that smells like urine can be a sign of kidney disease.
An unusually foul odor accompanied by vomiting, lack of appetite, and yellow-tinged corneas or gums could signal a liver problem.
Having bad breath can be signs of GI problems, diabetes, kidney failure, dental infections, and many more harm-causing ailments.
