Can my dog suddenly become allergic to the food they've been eating for months?

My dog has been happily eating the same brand of food for several months, but recently I've noticed he's been scratching more and has a slightly upset stomach. I’ve always thought food allergies were something pets were born with, so I’m puzzled by this sudden change. Is it possible for dogs to suddenly develop allergies to foods they've eaten without issues before?

Answer

Yes, it is possible for dogs to develop food allergies even to foods they have been eating without problems in the past. These can manifest as skin issues and gastrointestinal upset.

  • Increased scratching or itching
  • Upset stomach, including vomiting or diarrhea
  • Red or inflamed skin
  • Ear infections

Food allergies in dogs can develop over time as their immune system changes or with repeated exposure to an ingredient. Identifying and managing these allergies is important to keep your dog healthy and comfortable. An elimination diet, where potential allergens are removed from the dog's food, can help identify the source of the allergy.

If you are concerned about your dog’s health, consider contacting a professional for guidance. Book a consultation with Dial A Vet to discuss your pet's symptoms with a licensed veterinarian.
