Human beings are not the only species that can suffer from allergies. Dogs can also have allergic reactions to objects in the home, chemicals and pollutants in the air, dog food, and their own hair and dander.
Finding the source of these allergies can be difficult especially if the dog is allergic to a few things.
If you have a dog that suffers from allergies, you may notice that they sneeze when around harmful chemicals, vomit after eating, have skin rashes, patches of fur missing, runny nose and eyes, or they may show signs of fatigue or restlessness.
Noticing these signs is the first step to helping your dog lead a normal, healthy life. You should monitor your dog for a month to see how it reacts to its environment, its food, and its own hair and dander.
Since dogs need to keep themselves clean, they may be swallowing allergens that can cause an allergic reaction. The best way to combat a hair and dander allergy is to bathe your dog once a month and brushing the dog once a day.
