Dog food allergies seem to affect both male and female dogs alike, but in two recent studies is was found that certain dog breeds may have a risk for the development of dog food allergy.

The breeds noted included: Springer Spaniel, Miniature Schnauzer, Labrador Retriever, Soft-Coated Wheaton Terrier, Dalmatian, West-Highland White Terrier, Collie, Chinese Shar Pei, Llasa Apsa, Cocker Spaniel, Dachshund and the Boxer.  Data from a Colorado State University sudy shows that retrievers may be at greater risk to develop food allergy than other breeds. Reports also show that animals less than one year old may have a greater chance of developing a dog food allergy.

Clinical Signs of Dog Food Allergy

The most common symptom of a dog food allergy is non-seasonal pruritus (chronic itching), which is usually generalized but may also be primarily focused at the feet or ears. The most common skin problems are papules (a small, solid and usually conical elevation of the skin) and erythema (reddening of the skin) common secondary problems are epidermal collarettes (a circular lesion with a circular rim of scale and or a peeling edge), pyotraumatic dermatitis (hot spots), hyperpigmentation, and seborrhea (the accumulation of scales of greasy skin).

Gastrointestinal (GI) signs caused by dog food allergies seem to be rare; although, a recent report documented 20 dogs with both pruritus and GI signs typical of colitis (inflammation of the large intestine which usually leads to abdominal pain, fever, and diarrhea with blood and mucus). Both the skin problems and intestinal signs resolved after the dogs started on an elimination diet.

Neurologic signs such as malaise and seizures rarely have been reported. The author feels that malaise may be under-reported, as an increase in energy level (“acting like a puppy, feeling better”) is often noted upon feeding the dog a diet without the offending allergen; this may occur before cessation of pruritus. Respiratory signs, such as asthma, have also been reported, but seem to be quite rare.

Concurrent hypersensitivities have been reported in dogs and include atopy, flea allergy dermatitis, intestinal parasite allergy, and even an allergy to bovine insulin. Concurrent pyoderma and/or Malassezia pachydermatis infection is also common. Dogs may have pyoderma (infection of the skin) as the only clinical sign of a dog food allergy. These dogs are often clinically normal while receiving antibiotics. Therefore, it is important to diagnose and treat secondary infections, as persistence of pruritus due to these infections may confound the ability of the veterinarian to diagnose the underlying dog food allergy.

Here is the story By Barbara Kremers:

How allergy signs can affect your life.

This is the story of an otherwise very happy Labrador Retriever with concurrent allergies. It is based on an interview held with Nell Kremers.

Scratching for Relief

Demi is a friendly Labby, she’s always happy and playful, or at least she used to be up until one summer at 15 months of age. She then just started biting and scratching. As if the itching drove her mad she was iterally rubbing and licking her skin away. The once beautiful chocolate-brown Labrador lost her shine.

She showed bald spots in her arm-pits and below her tail plus self-inflicted wounds in her face. Scratching for relief of allergy symptoms does cost a lot of energy.

At first it just seemed as if she had developed a bad habit and the owners at first tried to correct her for overdoing the scratching thing as perhaps she was just seeking attention being in the puberty age. Demi, the docile dog she is, obeyed and stopped the scratching as long as one of her human family members was around. But as soon as they left the room, she would make up for lost scratching time and hit it like crazy. Also when she got aroused and her blood started flowing more quickly through her veins, it appeared the itching increased.

Change to Hypo-Allergenic Dog Food

And so it happened she was taken to the vet (well, not for the first time of course). She showed self-inflicted wounds and around her eyes virtually no hair had survived the intense scratching. The vet checked her for parasites and teeth problems (as she was scratching around her jaws as well) but found no problems in that area. He then advised to change her dog food from high energy Eukanuba to Lamb & Rice, to rule out a dog food allergy. Lamb & Rice is a combination that is often prescribed as a low-allergen dog food and the rationale behind it is that dogs won?t have eaten this before. However, nowadays Lamb & Rice is not such an exotic dog food anymore? and in this case this choice was not so fortunate for Demi.

Demi has a very loving owner who would sleep on the couch, during the heavy episodes, just to be in time to calm her down. No more scolding or shouting to try to stop her hurting herself, but instead remaining calm and trying to transfer tranquillity to her (as if giving Reiki to a dog). The owner would gently let her hands go over the itching spots, which gave Demi some relief. This was to avoid Demi mutilating herself as the self-inflicted wounds can progress and get infected (so called hot spots).

However, the symptoms did not disappear and she was taken to the veterinarian again. She received a medicine to relief the itching and, thank goodness, this worked so she could have some sleep again. Poor Demi had not enjoyed a good night of rest for quite some time and this was taking his toll as well, changing her behaviour and making her more nervous. She also got antibiotics and a skin sample was taken for further research. No parasites or scabies was detected.

Allergy Blood Test

Standard treatment in itching is to change dog food for about 3 to 4 months and to only give your dog that dog food, no treats, no snacks, no table scraps, nothing whatsoever. When symptoms remain, then a blood test is indicated. And Demi obviously qualified for this next step. Finally it all became clear. Just have a look at the results below.

Demi’s allergy test revealed the following allergies:

*Food allergies: Rice, wheat, lamb, soy, carrots and nuts with highest score for rice and wheat.

*Contact allergies: Various mites and also flea bite allergy

*Inhalant allergies: Wheat (again), barley, corn, oats, stinging nettle and ribwort plantain.

Demi was suffering from multiple allergies such as grass allergy which explained the increase in allergy symptoms during summers (like the first episode) but also a  very high score to rice and to a lesser extent to lamb as well, the main ingredients in her so-called hypoallergenic dog food. What an unfortunate choice this had been! With this new knowledge, she was immediately taken of Lamb & Rice and transferred to Duck & Potato Diet (Tovet’s DPD).

Desensitization via Allergen Injections

To deal with the inhalant and contact allergies for grain and grasses, immunotherapy was indicated. It’s pretty easy to ‘cure’ dog food allergies (the cure is to just eliminate the ingredients from the menu) compared to curing environmental allergies. It is often impractical to keep a dog away from offending allergens, so another solution than elimination is required. Based on the results of the allergy test a special mix was created in the laboratory to desensitize Demi to the identified culprits.

Since this involves weekly injections the owner had to learn how to inject Demi subcutaneously with these liquids. This kind of therapy thus requires a dedicated dog owner and it can be quite difficult to inject your own pet (well, that’s my personal experience). The owner was given three kinds of fluids (red, green and blue caps) and the amount was set for a period of 6 months of therapy. There is a small risk of anaphylaxis, but still it’s the safest long-term treatment available. About 70% of treated dogs respond well to immunotherapy and the others at least show some alleviation of the clinical symptoms.

Learning to Live With Dog Allergies

Demi is now four years old and most of the time she is a happy dog. She will receive desensitization injections (maintenance dosage) probably for the rest of her life. To relief any itching that remains here’s a tip from Nell that works for Demi: dilute some tea-tree oil in water and spray this on the inflicted areas. It reliefs the itching, desinfects the skin and helps the healing process of hot spots.

Knowing what allergies she has, she can enjoy an occasional treat again (though never dog biscuits or any other kind of treat that contains wheat such as most dental sticks). Luckily Demi just adores fruit and cheese which is safe to eat for her! You can make Demi really happy by offering her pineapple, mango, strawberries, cucumber, apples and pears. But she also loves a piece of bread, though she’s allergic to the ingredients.

People passing by on the street sometimes want to offer a dog biscuit to this happy furry lady, but of course this is strictly prohibited. And since everyone would get tired of explaining the ins and outs of this decision, some people don’t understand why this Labrador isn’t allowed to enjoy a tasteful treat. Also bread left on the grass for the ducks to eat is a risk for Demi. Especially when walking in the dark it’s not always easy for the owner to intervene on time.

Should the allergy episodes worsen again, then there is  one official remedy left: Prednisone injections. Antihistamines, though beneficial in allergic humans, give inconsistent results in dogs. So that leaves us with steroid treatment. Counter effects of prednisone are that it can damage the organs and as such may decrease life span. Though when all else fails it’s like Demi’s owner stated: “Better be happy for a few years, than a very long life of discomfort and unhappiness”.

However, before turning to Prednisone as final resort it appears good results are booked with a holistic approach in similar cases. This is a non-traditional approach in veterinary medicine exploring alternative and complimentary areas of health care. Let’s hope new therapies and treatments are discovered to prevent and cure diseases in our beloved pets.

So what can we learn from this story about allergy:

*Prescribing Lamb & Rice dog food to rule out dog food induced allergies is not a good choice in all cases.

*Dog food induced allergies, inhalant allergies and contact allergies can occur at the same time making a clear diagnosis very difficult.

*When your dog is suddenly scratching a lot, examine his coat for fleas or other parasites and take him to the vet if your investigation was negative.

*When your dog suffers an attack of heavy itching and is relentlessly scratching for relief, try to transfer calmness to your pooch. Diluted tea-tree oil can give some relief.

*When you meet a person who is walking a dog that looks like he has some kind of contagious disease, don’t immediately assume it is scabies and treat them like pariahs. You can just ask. When the other dog is suffering from allergic symptoms you need not worry. Let dogs be dogs if they want to play together. There is nothing contagious about allergies.

*Allergies cause great discomfort to both dog and owner and it is pertinent to try and identify the allergens that are causing this as quickly as possible.

*Holistic veterinary medicine may shine new light on this subject when traditional therapies fail.

You need to take responsibility for your dog’s safety and health because politicians and bureaucrats cannot be depended on to protect the pet food supply.  The story focused on the FDA’s Amendment Act that Congress passed into law in September 2007. “FDAAA was established by Congress to protect all foods, human and pet and requires that the FDA establish pet food ingredient standards and definitions, processing standards for pet food, and provide updated standards for the labeling of pet food that includes nutrition and ingredient information. Briefly, FDAAA asks for a total reform of the existing pet food regulations. These new standards and definitions must be established within two years (September 2007-September 2009).”

You would think that this action would start a new effort towards pet food safety regulations from the FDA, especially considering the last years pet food recall disaster.

According to Ms. Thixton “that’s not what is happening. Instead of working on reform, the FDA is relying on an incomplete five year-old program that is chock full of loopholes and gaps to meet the requirements of FDAAA. In fact, the day before the May 13th pet food safety meeting, the FDA released the latest version of this dated program implying this dusty ill-effective work meets the requirements of FDAAA.  AFSS is a five year-old program that is full of loopholes the FDA refers to as ‘gaps’ and is full of more problems for pet owners.”

Some of the gaps include:

- AFSS is relying solely on pet food manufacturers to determine risks and to provide a solution for these risks.

- the AFSS accepts the AAFCO (American Association of Feed Control Officials) ingredient list which sacrifice the public interest for industry desires.

- AFSS has been in the works for five years and the latest version acknowledges 14 significant gaps. There is no end in site.

Her final comment: “It is perplexing how Congress can pass a new bill (FDAAA) which requires the FDA to update and reform pet food safety standards, yet the FDA seems to ignore this. Perhaps they told Congress their patented excuse, “we don’t have the funding or the manpower to get this done” as to why they are using an outdated ineffective system instead of the mandated reform. Sounds similar to a child telling the teacher ‘the dog ate my homework’, except in this case the ‘excuse’ is working.”

The full article can be read at http://www.naturalnews.com/023995.html

My final thought:  You must take responsibility for your pet’s health and welfare and make sure that you are providing quality food for your pet.  This may mean making it yourself or thoroughly researching the dog food manufacturer to make sure they are reputable and acting responsibly.

Obesity in pets can lead to heart disease, diabetes, high blood pressure, arthritis and other health complications just the same as for their owners.

The reasons seem to be the same too, according to Dr. Diane Frank, Canadian animal behaviourist and president-elect, CVMA.

“It comes down to excessive caloric intake, behavioural issues, improper reward systems and an inactive lifestyle — all which can apply to both pets and humans. The key difference, though, is that pets don’t have control over the choices made for them — that’s the owner’s responsibility and they need to be prepared to recognize and deal with the issue.”

Feeding treats can have startling consequences.

Here are some examples:

One ounce of cheese to a small dog is the same as you eating one and a half hamburgers or one and a half chocolate bars.

For a cat, one ounce of cheese equals three and a half hamburgers for you.

Eight extra pounds on your pet is the same as 30 extra pounds on you (based on 150-pound human and a 40-pound dog).

To determine if your dog is overweight run both hands along each side of your pet, you should see and easily feel the ribs. As your hands pass the ribs, they should then come in slightly for a nice tuck in the waistline.

If the ribs are not visible and you have to press in to find them, your pet is in need of some urgent action.  Action being the key word here.

Your pet will benefit from an activity treat than they will from food.  It’s better to provide positive attention and stimulation through exercise or play rather than food.

Cutting calories is as important as increasing your pet’s exercise level. Measure the food your get is getting and if you do give treats during the day as a reward, reduce the main meal accordingly.

Also make sure to feed your dog food that is rich in nutritional quality so their body has what it needs to be healthy and lose weight more easily.

Roughly 20% of the dogs suffer from some allergy type. Major allergies found in dogs include atopic dermatitis, flea allergy, food allergy and inhalant allergy.

Dog Food Allergy

A dog food allergy is probably the most tedious of dog allergies to diagnose because dog food allergies can mimic the symptoms of any of the other allergies mentioned above.

Other symptoms of food allergies are stomach problems, gas, vomiting, diarrhea, wheezing, ear infections and sometimes, even changes in behavior.

To find the food or foods that your dog is allergic to you must first remove all the possible allergy causing ingredients from your dog’s diet. The easiest way to do this is by using a homemade meal of a protein and starch source that your dog has not had before. Then gradually add more ingredients into it over time (every 2-3 weeks). The most common allergens tend to be protiens, such as meats and grains. If your dog’s symptoms return after adding a particular ingredient, then you may have identified the possible allergen.

Allergic reactions may not appear for about a week after consuming the allergen so confirm your findings with your vet. Obviously, once you have determined the offending ingredient you will need to avoid it in the dog foods you feed your pet.
