If you are concerned that your dog may have an allergy, it may take a while to isolate the cause. If your dog eats a lot of different things regardless of whether you want him to or not, it may be a tough undertaking. The dog may have skin problems be vomiting for other reasons other than dog food allergies.

One of the first things you need to do is to take your dog to the veterinarian. Doing this you can find out if the symptoms are being caused by problems. If everything else has been ruled out, it is now time to see if the problem is the food he is eating.

Starting the process and staying with the process for isolating the allergen takes some dedication on the owner’s part. A lot of different things can cause a dog food allergy such as beef, pork, chicken and lamb. These are also very common foods that dogs eat. That is why if you suspect something in particular you will have to stay with eliminating the food from the diet and then proceed. This can take around twelve weeks to isolate.

If you feed your dog dry dog food, it can be one of the ingredients or additives in the food. If it is a food that has three main ingredients such as pork, lamb and fish, it will be extremely difficult deciding the problem and then eliminating it. It may be easier to put you dog on a one item diet for a while and then go from there.

Dog food allergies are very common and with a little dedication can be eliminated and your dog can be happy once again.
