Identifying Common Symptoms

Food allergies in dogs can manifest in various ways, and recognizing these signs early can prevent more severe health issues.

Skin Reactions

  • Itching and Scratching: Persistent itching is a hallmark of food allergies. Dogs may scratch excessively, leading to skin irritation or infections.

  • Red, Inflamed Skin: Allergic reactions often cause redness and inflammation, particularly around the ears, paws, and stomach.

  • Chronic Ear Infections: Frequent ear infections can indicate an underlying allergy, often exacerbated by yeast growth.

Digestive Issues

  • Vomiting: Dogs with food allergies may vomit after meals, especially if they consume a trigger food.

  • Diarrhea: Loose stools or diarrhea can be a sign of gastrointestinal discomfort due to an allergic response.

  • Flatulence: Excessive gas can accompany other digestive symptoms, indicating a potential allergy.

Common Allergens in Dog Food

Typical Culprits

Certain ingredients in dog food are more likely to cause allergic reactions.

  • Proteins: Beef, chicken, lamb, and dairy are common protein sources that can trigger allergies.
