Always consult your veterinarian before administering doxycycline to your dog. While generally safe, side effects can occur. These may include gastrointestinal upset (vomiting, diarrhea, loss of appetite), increased thirst or urination, and changes in liver enzyme levels. Less common, but potentially serious, side effects involve allergic reactions (skin rash, itching, swelling). Observe your dog closely for any unusual symptoms and report them immediately to your vet.
Doxycycline can interact with several medications. This table highlights some key interactions:
| Antacids (e. g., calcium carbonate) | Reduced doxycycline absorption | Administer doxycycline at least two hours before or after antacids. |
| Warfarin (blood thinner) | Increased risk of bleeding | Close monitoring of blood clotting is required. |
| Dairy products | Reduced absorption | Avoid giving dairy products with doxycycline. |
| Some antibiotics | Potential interactions | Inform your veterinarian about all medications your dog is taking. |
This information is not exhaustive, and other interactions are possible. Always provide your veterinarian with a complete list of your dog’s medications, supplements, and even over-the-counter drugs to ensure safe and effective treatment.
