Clavamox is a prescription pet antibiotic for dog urinary tract infection treatment or to counter other types of gram-positive or gram-negative bacterial infection in pets. Clavamox for dogs may also be indicated for treating skin infections in a pet's cuts or wounds, and it may also be used to treat dog bladder infections. This medication works by making bacteria unable to build cell walls so they cannot grow, and this clears the infection. Some vets may recommend Clavamox as a more effective antibiotic depending on the type of infection. You can buy Clavamox with a prescription, and your best price on it will be when you order pet medication online from Canada Pharmacy.
