There are several causes for allergies in dogs. The symptoms are similar to human allergies. Some of the symptoms include itchy flaky skin, red spots, and/or hair loss.
Dogs who suffer from allergies year round, may be suffering from a food allergy. The main culprits are protein based foods to include wheat, corn, or soy products. However, as with humans, your dog may be allergic to something completely different and unexpected. Other possibilities are soaps, flea treatments, perfumes, or other topical substances.
One simple way to determine what is bothering your dog is to eliminate one item at time and observe your dog’s reaction. If the constant scratching stops, you most likely found the culprit. I like to record my dog’s unusual behaviors on a calendar.
For example, if my dog is sleeping more than usual, acts lethargic, scratches constantly, or displays any other behavior that is not usual for him, I write down the behavior on a calendar. Plus, I keep a record of what my dog ate, weather conditions, or what shampoo I used. Then, I review what was different that particular day or week. I check the pollen count for the time period as well as the mold count. This has allowed me to identify my dog’s allergic reaction to pollen and wheat products. Next, take the record with you to your dog’s next Veterinarian appointment to discuss treatment options.
There are several treatment options available for dogs. Several are inexpensive and easy to use. For my dog, his veterinarian prescribed an over-the-counter antihistamine for days when the pollen counts are high. Plus, I changed his food and treats to a wheat-free brand. This made a huge difference in his quality.
