Managing dog allergies: distinguishing food from environmental allergies, symptom treatment, how to conduct an elimination diet trial, and everyday preventive measures.
Dog allergies have been on an increasing trend in recent years, with approximately 10-15% of dogs visiting animal hospitals presenting allergy-related symptoms. We provide a detailed explanation of dog allergies—which include itching, dermatitis, and digestive symptoms that greatly reduce their quality of life—from identifying the cause to treatment methods.
Dog allergies are broadly classified into three types.
Food allergies occur when the immune system overreacts to proteins in specific foods. Main symptoms include itching on the face and paws, ear inflammation, and diarrhea or vomiting. Beef, chicken, wheat, dairy products, and eggs are common culprits, with symptoms typically persisting year-round.
Environmental allergies (atopic dermatitis) are caused by environmental allergens such as pollen, dust mites, and mold. Itching on the abdomen, paw pads, and armpits is typical. If seasonal, pollen is suspected; if year-round, dust mites or mold are likely culprits.
Flea allergies result from reactions to flea saliva. Itching and hair loss from the lower back to the base of the tail are characteristic, with severe symptoms appearing even after a single flea bite.
The elimination diet trial is the most reliable method for confirming a food allergy diagnosis.
In an elimination diet trial, you feed only novel protein foods (such as venison or kangaroo meat) that the dog has never eaten before, or hydrolyzed protein foods for 8-12 weeks. During this period, treats and other foods are strictly prohibited. Once symptoms improve, gradually reintroduce the original ingredients one at a time to identify which foods trigger a reaction.

Environmental allergies are difficult to cure, so symptom management is the focus of treatment.
Recently, oclacitinib (Apoquel) and cytopoint (antibody injections) have become the mainstream medical treatments. They have fewer side effects than traditional steroids and can be used long-term. They are highly effective at reducing itching and improve quality of life in many dogs.
The following daily management strategies are effective:
Dogs with allergic predispositions have compromised skin barrier function, making skincare essential.
Regularly use ceramide-containing moisturizers and sprays to support the skin's moisture-retention function. Essential fatty acid (omega-3 and omega-6) supplements help reduce skin inflammation and improve barrier function. Fish oil dosage is typically 50-75 mg daily of combined EPA and DHA per kilogram of body weight.
Choose medicated shampoos based on symptoms. Oatmeal-based shampoos work well for itching, chlorhexidine-based shampoos for bacterial infections, and sulfur or salicylic acid-based shampoos for seborrhea. Remember to moisturize after shampooing.
Since allergies are a constitutional issue, learning to manage them well is more important than seeking a cure.
Receive regular veterinary checkups and adjust treatment according to symptom changes. During seasonal transitions and rainy seasons when allergies often worsen, starting preventive medication is effective. For diet, avoid allergenic ingredients while maintaining nutritional balance, and consider using probiotics to support intestinal health.
Through br-choku, you can bring home a dog from breeders who understand breed-specific allergy tendencies. The ability to confirm genetic information in advance—such as the parents' allergy history and siblings' health status—is a unique advantage of direct breeder sales.
