Always monitor your dog closely for any adverse reactions. Common side effects include vomiting and diarrhea. These usually are mild and resolve without treatment, but persistent or severe vomiting or diarrhea requires veterinary attention.
Gastrointestinal Issues
Amoxicillin can upset a dog’s stomach. Besides vomiting and diarrhea, decreased appetite is possible. Providing bland food like boiled chicken and rice might help, but consult your vet if symptoms persist or worsen. Dehydration is a serious concern with prolonged vomiting or diarrhea; watch for decreased urination or lethargy.
Allergic Reactions
While rare, allergic reactions can occur. Watch for skin rashes, hives, itching, or swelling of the face, lips, or paws. These are serious and require immediate veterinary care. Anaphylaxis, a severe allergic reaction, is a medical emergency.
Other Potential Side Effects
Less frequent side effects include changes in behavior (such as increased lethargy or hyperactivity), and dark or bloody urine. Report any unusual symptoms to your veterinarian. Regular blood work can help your vet monitor kidney and liver function, especially with long-term amoxicillin use. Your vet can guide you on appropriate dosages and monitor your dog’s response to treatment.
Medication Interactions
Amoxicillin can interact with other medications. Always inform your veterinarian about all medications your dog is taking, including supplements and over-the-counter drugs. This prevents potential complications.
