1. **Vomiting or Diarrhea**: If your dog suddenly starts vomiting or has diarrhea after starting a new medication, it could be a sign of an adverse reaction.
2. **Lethargy**: A noticeable decrease in energy or enthusiasm for activities they normally enjoy can be a red flag.
3. **Changes in Appetite**: If your dog refuses to eat or suddenly starts eating significantly less, it may be reacting negatively to the medication.
4. **Behavioral Changes**: Look for increased irritability, anxiety, or aggression that is out of character for your dog.
5. **Skin Reactions**: Watch for signs of allergic reactions, such as itching, redness, swelling, or hives.
6. **Excessive Thirst or Urination**: Some medications can cause increased thirst or urination, which may indicate a problem.
7. **Seizures or Tremors**: These are serious symptoms that require immediate veterinary attention.
If you notice any of these signs, it is crucial to contact your veterinarian right away. They may suggest adjusting the dosage, switching medications, or providing supportive care depending on the severity of the reaction.
Always monitor your dog closely when introducing any new medication, and keep a list of any changes you observe to share with your vet. It’s also a good practice to discuss potential side effects with your veterinarian before starting any new treatment.
