In most regions of Quebec, we are in ragweed season. This plant is a major cause of allergies in dogs and affects 85% of people who suffer from allergies. The term atopy is used to describe this type of allergies in dogs. Generally, when a dog is allergic to ragweed, it will usually suffer from mid-August to November every year. Unlike runny eyes and noses in humans, the main sign of atopy is itching. The animal rubs its head, including the ears, nose and eyes. The itching can even spread throughout the body, and the dog will chew and lick its paws. Many of these dogs will have a discoloration of the paws, caused by the saliva, which is fairly typical. Without treatment, atopy can produce secondary infections and those infections can increase the itching and complicate the treatment. If you suspect that your dog has allergies, consult your veterinarian. Your dog will thank you for it.
