Dog ear drops

Ours swim daily too, and one is prone to ear infections. After several vet visits, we just stop at one of the two vets across the street from the Mercado, on the Santander side.

These are the drops that work for us: Gotikas, in a dropper bottle, we put them in twice a day for a day or two until the head shaking stops. Usually we can catch it early and only use them once or twice. I think they are about 100 pesos.

Good Luck!
