Pin-pointing Allergies
Renee Bergeron asks, via our Facebook Wall:
“I have a foster pug-girl right now, and she is on a low residue prescription diet. She has been on this diet for the last week. She has some yeast infections on her skin and patches of no fur growth on her legs, and underbelly. The low residue food is to try and isolate her allergies – However, I do not know if this is… the treatment I would have chosen. If there is no improvement in the next 2 weeks, I would like to try one of your products. My three dogs are on Keen, and they love it. But, I need something for my foster girl that will help isolate whatever allergen is causing the yeast. Any help?”
There is actually a difference between a ‘low residue’ food and an ‘elimination diet’ though they are sometimes confused with one another. A ‘low residue’ diet is usually recommended for problems related to the digestive system, and is designed to be very easily metabolized and results in very minimal stool volume. Unfortunately some low-residue diets contain ingredients like chicken by-products, corn-grits and beet pulp to help minimize ‘residue’ or stool volume and these can actually trigger off allergies in their own right! An ‘elimination diet’ on the other hand, is used almost as a diagnostic tool, to help a vet or pet owner to isolate and pinpoint pet food allergies or intolerance.
I am not sure if you were mistakenly referred to a low-residue food for your foster girl, or you are in fact following an elimination diet. What I’d really recommend, is the true elimination diet, and here’s how it works.
Start off feeding an ultra simple diet of ideally, just two ingredients. Many vets recommend turkey and sweet potatoes, and nothing more. You’ll probably have to home-make these meals for the test period. The idea here is to ‘eliminate’ everything else from the diet in the hope that the allergies or yeast infections will at least begin to show signs of starting to subside. (If they don’t, try just turkey and quinoa or maybe beef and sweet potatoes instead). Don’t feed any other foods or treats at all, as these can throw off your results.
Feed this ultra-minimal diet for about 2 to 3 weeks and possibly even longer, to observe for improvements. You probably won’t see a complete cure but you should start to see a little less itching and irritation. Once she is at this point, you can begin to very slowly add additional ingredients, one at a time only, at a rate of one every one or two weeks. Don’t feed any other treats or ‘unplanned’ foods still. Keep a record of what you’re adding in each week and what reactions if any, occur. You may find you can add green beans one week and oatmeal the next but as soon as you add flax, she gets all itchy again. Note this, take out the problem ingredient, and make a note of it.
It’s a time consuming process involving a certain amount of trial and error, but an elimination diet really can work in helping you to work out what foods your Pug can and can’t tolerate. Some pet owners are amazed to discover that their dog can tolerate almost anything that’s home-made, raw or minimally processed yet the moment they switch to a highly-processed kibble of the same ingredients, the allergies flare back up. There are a couple of suspected reasons for this: Either the kibble is laden with chemical preservatives which are causing the reaction, or it was processed under such extreme heat and pressure that the amino acid structure of the raw ingredients was altered and your dog’s body can’t even recognize that ‘chicken meal’ as true chicken!
Once you’ve pinpointed her allergies, you can either continue to home prepare her meals, or try her on a very minimally processed diet with just a few simple whole-food ingredients. Many people have success with our Thrive recipe, which is chicken and quinoa (an ancient, gluten-free seed) plus vegetables – no fruit or flax.
If you don’t have the time to home-make your dog’s meals, the other approach is to feed a completely grain-free diet for a few weeks and see if that does the trick. Wheat, corn, soy, rice and beet pulp are by far the most common causes of pet food allergies. Gluten (in wheat and corn) can be problematic and the fact that these grains are commonly genetically modified here in the USA are thought to be contributing factors. Also, the sugar content in grains has been linked to excess yeast growth which can cause issues like those you’re describing in your Pug. Our Embark and Force are both 100% grain-free, as are most of the commercial raw food diets on the market.
I hope that helps! let us know how you get on!
