1. **Itching and Scratching**: One of the most common signs of allergies is persistent itching. Dogs may scratch at their skin, bite at their paws, or rub their bodies against furniture or the ground.
2. **Red or Inflamed Skin**: Allergies can cause the skin to become red, inflamed, or irritated. You may notice hot spots or areas where the fur is thinning due to excessive scratching.
3. **Ear Infections**: Allergies can lead to recurrent ear infections, which may cause your dog to shake their head frequently, scratch at their ears, or have a foul odor coming from the ears.
4. **Watery Eyes and Nasal Discharge**: Dogs with allergies may have watery eyes or a runny nose. This can be similar to how humans react to allergens.
5. **Gastrointestinal Issues**: Some dogs may experience vomiting or diarrhea as a result of food allergies or sensitivities.
6. **Behavior Changes**: Allergies can also affect a dog's behavior. A normally playful dog may become irritable or lethargic due to discomfort.
If you suspect your dog has allergies, it's best to consult with a veterinarian for a proper diagnosis and treatment plan. They may recommend allergy tests, changes in diet, or medications to help alleviate your dog's symptoms.
