Dogs have different reactions to certain types of foods and allergies spring up from uncommon sources of food, for instance some dogs are treated for some types of sensitivities, it is recommended they you give them a diet made up of lamb based foods, it cannot be denied though that other dogs are completely allergic to lamb.
There are also some dogs which require high quality food while a few thrive on low quality food. This only goes to show that each dog is different. Generally, it would be better to start with high quality food that can provide your dog with a healthier diet. However, if you discovered that this type of food does not suit your dog, try lower quality alternative. If you are worried your dog is not getting all the nutrients it needs or it looks unwell, you should visit a veterinarian. They basically know the types of foods that are most nutritious for your pet and can suggest you to add supplements to its diet whenever necessary.
Here is a list of nutrients that are likely to trigger an allergic reaction to your dog.
Foods which include any of the above given nutrients must not be given to your dog if they have an allergic reaction to the food they eat. The most common symptoms of food allergy or intolerance include frequent ear infections, vomiting or diarrhea, a dull coat, frequent licking of the face, groin and armpits and hot spots on the skin or itchy, dry scaly patches. If your dog manifests these signs, it may be the perfect time to go to a vet.
The vet can perform blood test in order to distinguish if your dog is suffering from food allergy or intolerance. There are some brands of dog food that have two or even more sources of meat as their main ingredients. Some nutritionists and vets believe it is best to have only one source of animal protein. The next set of ingredients can be carbohydrates which include rice, potatoes, sweet potatoes or oats. These are not required by dogs but can actually make good filler.
Dogs need some fats like fish oil, olive oil or poultry fats. However, you should not give them food that has corn oil and sunflower oil. It is important to know the actual type and source of fat to make sure you are getting only the good ones or those that your dog is not allergic to.
Brewer’s yeast is another nutrient that typically causes allergic reactions to dogs. You should be careful of foods that contain this. To be safe, it is better to choose probiotics. If your dog needs to take supplements, make sure it is done with caution and under the advice of a veterinarian. If your dog takes excess supplements especially during its growth stage, it may cause your dog permanent damage.
When you already established a diet that suits your dog well, make sure to not over feed. Set a a routine for your dog with sufficient amount to keep it healthy.
