Itchy dogs and cats, the link between inflammation and diet
Sunday, May 16th, 2010
One of the most frustrating problems is veterinary medicine is the chronically itchy dog or cat.
So how can be get these guys so they are comfortable without getting stuck in the constant swing between steroids and antibiotics and without spending a small fortune?
Lets look at what is going on.
Why do dogs and cats itch?
Most itchy animals are allergic to something, be it food, plants in the environment or some other thing in their world such as dust, molds, or chemicals. The hard part is finding out what it is and even harder being able to do something about it. I have a number of dogs in my practice who are allergic to humans, dust, or grass which are all impossible to eliminate from their world.
Allergies produce inflammation in the body. In people this often presents as nasal congestion, in animals the most common way inflammation presents is through the skin.
So if they are allergic to something we can not eliminate this is an impossible problem, right?
No, there is hope.
Most animals and humans have some mild allergies or sensitivities. Most of the time we do not have any problems from them but if we are suddenly exposed to everything we are allergic to all at once or a very large amount of something we are allergic to we have a reaction. This is because we only have a reaction if the inflammation in our body reaches a certain threshold. Below that threshold nothing happens.
But my dog is allergic to everything and always itchy. How do I possibly get his body to be below the allergy threshold so he doesn’t itch?
Through using a diet that reduces the inflammation in his body! This means we need to feed a diet that is not processed, doesn’t have grain and takes a little longer to get absorbed and assimilated through the gut. A slow assimilation assures that there are not large spikes of nutrients and proteins that come into the body all at once and overtax the pancreas and liver creating inflammation.
Most commercial diets are too high in grains and carbohydrates and too processed for our companion animals. They create inflammation which overtaxes the body and leads to not just skin inflammation but also other inflammatory conditions such as colitis, pancreatitis, arthritis, inflammatory bowel disease, and ear infections.
In addition many of these diets are not high enough in protein causing a decreased blood reserve in the body in some of these animals which leads to the skin not being properly nourished and a cycle of chronic skin infections which produce more itching.
Commercial high grain processed diets often make our animals overweight. Fat reserves in the abdomen cause more inflammation in the body, by producing free radicals, adding to the problem.
So what are the steps needed to raise the allergy threshold and stop or eliminate the itch through diet?
Remember that resolution of itching can take a long time. Many animals, especially the ones with severe skin disease, take up to a year to get better.
