Why Do Dogs Get Allergies?
Dogs can be allergic to many things. Sometimes, the allergy comes from the food they eat. Other times, it can be from pollen, dust, or fleas.
Food allergies usually happen when a dog’s body does not like a certain ingredient. Their immune system reacts badly. This causes skin problems, itching, and stomach issues.
Signs Your Dog May Have Food Allergies
- Itchy skin or red spots
- Hair loss in some areas
- Excessive licking or chewing
- Runny eyes or nose
- Upset stomach or vomiting
If your dog shows these signs, food allergies could be the cause.
How to Find the Best Dog Food for Allergies
There is no one-size-fits-all dog food for allergies. The best choice depends on your dog’s specific allergy. Still, some types of dog food work better for allergic dogs.
Here are the main ideas to look for:
- Limited Ingredient Diets
- Novel Protein Diets
- Hydrolyzed Protein Diets
- Grain-Free Diets
1. Limited Ingredient Diets
These dog foods have only a few ingredients. This helps to avoid allergens. It also makes it easier to find the cause of the allergy.
For example, some limited ingredient foods use just one protein and one carbohydrate. This reduces the chance of a bad reaction.
2. Novel Protein Diets
Novel proteins are new or rare proteins your dog has never eaten before. Examples include duck, venison, or salmon.
These proteins may not cause allergies because your dog’s body is not used to them. So, they can be safer options for allergic dogs.
3. Hydrolyzed Protein Diets
Hydrolyzed proteins are broken down into tiny pieces. This helps the immune system not to see them as allergens.
Veterinarians often recommend these diets for dogs with severe allergies. These foods usually need a prescription.
4. Grain-free Diets
Some dogs have allergies to grains like wheat or corn. Grain-free dog food can help these dogs feel better.
But not all dogs need grain-free food. Talk to your vet before switching.
