Yes, believe it or not, food allergies in dogs are a thing!<\/p>\n

However, there is still a significant number of pet owners who are not aware of what to do and how to spot canine allergy early on.<\/p>\n

\"White<\/a><\/p>\n

What Are Food Allergies in Dogs?<\/strong><\/h2>\n

Food allergies in dogs<\/strong> occur when their body mistakenly identifies a common food ingredient as harmful and overreacts to protect itself.<\/p>\n

It triggers a chemical compound called “histamine<\/a>,” which signals different immune cells that there's an invader to look out for.<\/p>\n

For example, when an allergen enters the body, the mast cells of the skin's dermis release histamine, which then attaches to the nerve cells<\/a> to trigger itching.<\/p>\n

Histamine also causes a runny nose, watery eyes, hives, and, worst,\u00a0anaphylaxis<\/a>, among other symptoms.<\/span><\/p>\n

Some pet owners might confuse a food allergy for food intolerance<\/strong>, or vice versa.<\/p>\n

While they're both caused by food our dog's bodies overreact to, food allergy involves the immune system<\/a>, while food intolerance involves the digestive system<\/a>,<\/strong> and is generally less severe.<\/p>\n\n\n\n\n\n\n\n\n\n\n\n\n
