As with most choices in the medical realm, there are both pros and cons of using colloidal silver for dogs, but for most people the decision comes down to ready availability, price, and history of success. Colloidal silver is usually considered an “alternative therapy” drug and is often used in place of antibiotics. It has a long history of use, and proponents often describe it as something of a cure-all. People give it to their dogs to treat almost any sort of infection or ailment. In most cases colloidal silver isn’t approved by government regulatory authorities for use as medication, though, and there can be concerns about strength, potency, and soundness of preparation. The lack of regulation can lead to a lot of variety in the products that are available, and there isn’t always a lot of consistency between brands. The risk of overdosing is rare but can happen, and prolonged use can lead to a number of canine health concerns.
Broad Spectrum of Uses
One of the biggest “pros” of colloidal silver for dogs is that it can be used to treat a huge range of issues. It is widely available in many natural food and health stores, and it isn’t usually nearly as expensive as the antibiotics and other pharmaceutical drugs that are often prescribed in its place.
