1. **Itching and Scratching**: One of the most noticeable signs of allergies in dogs is persistent itching. Dogs may scratch their skin, bite at their paws, or rub against furniture to alleviate the discomfort.
2. **Red or Inflamed Skin**: Allergies can cause the skin to become red and inflamed. This is often seen in areas like the belly, paws, and ears.
3. **Hot Spots**: These are localized areas of skin inflammation and infection that can develop when a dog excessively scratches or licks a particular area, leading to sores.
4. **Ear Infections**: Allergies can lead to recurrent ear infections, which may cause your dog to shake their head, scratch their ears, or have a foul odor coming from them.
5. **Watery Eyes and Nasal Discharge**: Just like humans, dogs can experience watery eyes and a runny nose if they have allergies, particularly if they are allergic to environmental allergens like pollen.
6. **Digestive Issues**: Some dogs may experience gastrointestinal symptoms such as vomiting or diarrhea, especially if they have food allergies.
7. **Changes in Behavior**: Allergies can make dogs uncomfortable, leading to changes in their behavior, such as increased irritability or lethargy.
If you notice any of these signs in your dog, it’s important to consult with a veterinarian for a proper diagnosis and treatment plan. They may recommend allergy testing, dietary changes, or medications to help alleviate your dog's symptoms.
