Food Allergy

When dealing with food allergies in dogs, the easiest way is to approach the elimination diet. If your furry pal shows signs like itching, swelling or gastrointestinal issues like diarrhea after eating a certain food, check out the ingredients present in it.

By eliminating certain ingredients, you’ll be able to figure out which food item was responsible for the allergic reaction.


Mites are usually present on the dog’s skin and can severely damage the dog’s skin. It can cause severe scratching in dogs and also deteriorate their health. Sarcoptic mange is even more dangerous as it can lead to hair loss and even rashes on the skin. Mites will appear dandruff-like so it’s easy to neglect it. However, it’s crucial to treat this issue to maintain the pet’s health.

Skin Infections

Some dogs have seasonal allergies which occur due to the release of allergic pollens into the environment. Dogs who like to play outdoors are more susceptible to such infections. Moreover, a cut or rash while taking a stroll around the park can also lead to a skin infection.
