1. **Persistent Symptoms**: If your dog is experiencing symptoms such as itching, scratching, or biting at their skin for more than a couple of days, it's a good idea to see a vet. Allergies can lead to skin infections if not treated.
2. **Severe Reactions**: If your dog shows signs of a severe allergic reaction, such as swelling of the face, hives, difficulty breathing, or vomiting, seek immediate veterinary care. These could be signs of anaphylaxis, which is a medical emergency.
3. **Gastrointestinal Issues**: If your dog has frequent vomiting, diarrhea, or other gastrointestinal issues that persist, this could be a sign of food allergies or intolerances. A vet can help identify the cause and recommend a suitable diet.
4. **Ear Infections**: Dogs with allergies often develop ear infections. If you notice your dog shaking their head, scratching at their ears, or if you see a foul odor coming from their ears, it’s time to consult a vet.
5. **Skin Infections**: If your dog has red, inflamed skin or if there are signs of bacterial or yeast infections (like odor or discharge), a vet can provide treatment and advice on managing allergies.
6. **Behavior Changes**: If your dog is more irritable, lethargic, or shows changes in appetite or drinking habits, it’s worth discussing with your vet as these can be related to allergies or other health issues.
7. **Unresponsive to Home Remedies**: If you've tried over-the-counter allergy medications or home remedies (like oatmeal baths or hypoallergenic diets) without improvement, a vet can prescribe stronger medications or suggest other treatments.
Remember, allergies can be complex and vary greatly from one dog to another. A veterinarian can perform tests to identify specific allergens and help create a tailored treatment plan for your furry friend.
