While you might want to prevent a dog itch, you will first want to know:

WHAT CAUSES DOG ITCHING?

Several popular dog breeds, such as the poodle and poodle crosses have an issue with skin allergies. They say that about ten percent of them have extreme itchiness.

While this can be caused by food it can also be caused by grasses.

I feed my dog a raw meat diet (including bones and offal) and while he has allergies caused by grasses, he does not suffer any itchiness caused by grains found in most manufactured dog foods.

If you want to know for sure, you can always take your dog to a skin allergy specialist where they will test your dogs allergy reaction to several known irritants.

HOW TO PREVENT DOG ITCHING

If you get hay-fever, and your dog has skin allergies, there is a good chance that they will be suffering elevated skin sensitivity at the same time that you are sneezing. Your dog may sneeze, lick its paws more often, or try to scratch its back by rolling on grass. Ironically of course is the point that the grass may be causing the itching and making it worse by rolling on it.

As you should always take your dog for a daily off lead walk, you are unlikely to keep them off the grass or weeds. However during extreme new weed periods, an anti histamine, as prescribed by your vet, can assist your dog as well as it assists humans. This is not a guaranteed method but well worth a try.

Another option, that has worked about 90% for my poodle cross is using Omega 3, from fish, with no additives in it. While Omega 3 is brilliant for every cell in the body, it is particularly good for a dogs skin, keeping it oiled and preventing bacterial and fungal infections, particularly in the feet pads and the ears. Note you need to get the dose right, do it regularly, and wait for up to four months for their system to catch up.

Of cause if your dog has chronic itching, you will need to see a vet. In this case they often prescribe a cortisone treatment for a week or so for the infected area, plus an injection to provide almost immediate relief.

NOTE Omega 3 is used in EVERY dog food, because it has to be to be classed as dog food, but it is in flax seed form that is very inefficient at being used by a dog. Essentially the average Omega 6 to Omega 3 ratio in most dog food is around SEVEN, but if Omega 3 from flax cant be converted the ratio goes up to 20 to 70 and that makes the Omega 6 of no value either. Dont be fooled, everyone who has a dog that itches should have Omega 3 in fish oil form, in the right dose level.
