Canine yeast infection can be caused by an overgrowth of the yeast cells. The yeast cells live on the skin of the dog, without causing any problems; however, when the number of yeast cells tends to be higher than normal, then there will be a pH imbalance and a yeast infection will occur. The infection may be localized in the dog’s mouth, ears, paws, reproductive area or spread over the entire body. This condition can be particularly uncomfortable for your pet, so it is essential to recognize the signs of a yeast infection. Some of the most obvious signs include excessive scratching and a bad skin odor.
Bad Skin Odor
When the dog has a skin infection, his skin will have a bad odor that is different from his typical odor. This odor is often described as an oily smell.
Pay attention to your dog’s smell when you groom him and consult a vet when you sense there is a change in your dog’s skin odor.
Extreme Skin Itchiness
The overgrowth of the yeast cells will cause the dog’s skin to be itchy and the dog will be scratching excessively. If the infection is localized in certain areas such as the ears, the dog will be scratching the ear area only.
Thickened Skin
If the yeast infection is left untreated, the dog’s skin will become thicker, due to all the scratching. The skin will also change its color and become darker or black in the most extreme cases.
Head Shaking
If the yeast infection is localized in the dog’s ears, the dog will also shake his head, as he will feel itchiness. The ears are particularly susceptible to yeast infections, as the environment is perfect: dark, warm and moist.
A yeast infection in the dog’s ears will also be signaled by an excessive production of wax. You may notice this when you clean his ears.
Licking and Chewing
The yeast infection causes itchiness, which can lead to a lot of licking and chewing; this may be present especially if the infection is localized in the dog’s feet.
Face Rubbing
The itchiness may cause your dog to rub his face against the wall, floors or furniture; this may signal that the infection is localized in the muzzle area. The dog may also scratch his face or put his paws on his face, attempting to relieve the discomfort.
The yeast infection in dogs may be caused by a number of factors, including antibiotics, allergies, bacterial infections or immune system problems. The cause of the infection must also be determined, so as to be able to apply suitable treatment and avoid the re-occurrence of the yeast infection.
The yeast infection may be diagnosed through a skin scraping test; other tests may be performed to rule out any other underlying causes. The treatment may consist of special shampoos, topical ointments and possibly other medications.
Yeast infections may be difficult to treat, however, if the treatment is administered correctly and the affected areas are kept dry and clean, the infection can be eliminated.
