You can get lots of FREE guidance from your pharmacist! And they DO know this stuff, lol. Why not ask what options may be out there? THEN run it all by the vet. If nothing else, you will have educated yourself so the discussion with the vet is easier for you to follow.

Baytril is another antibiotic, which can be used. There may also be others. Still a pill form, not the strong smell and taste of Clavamox. warning: Baytril COSTS!!! There may be one or 2 others as options as well.
