Best Dog Antibiotic for Skin

We enjoyed the PetSilver Wound Spray with Chelated Silver as an alternative to prescription products for skin-related issues. The spray effectively treats wounds and is safe for your dog to ingest if licked accidentally.

Chelated silver is one of the most beneficial ingredients that we’ve found for human and animal use. We’ve found value in keeping solutions with silver on hand in first aid kits since you never know when dogs will have stubborn wounds.

In a few instances, we found that this spray had minimal or no effect. However, the cases where this product worked as expected unnumbered the ones where it did not.

Types of Infections Common in Dogs

Ear infections and UTIs are some of the more common conditions that dogs get. Skin irritations from flea bites and allergies are also typical dog infections. Because some of these infections are antibiotic-resistant, owners need a range of solutions to consider.

Natural vs. Commercial Antibiotics

Natural antibiotics use ingredients like clove oil that are known for their infection-fighting properties. In many cases, they are less likely to produce severe allergic reactions. Although many commercial antibiotics require a veterinarian’s prescription, natural options are always available without a vet prescription.

Choosing an Antibiotic Type for Your Dog

Although most of us think of antibiotics being available as pills or tablets, these products are available as drops and ointment. The type of antibiotics that you use will depend on the type of infection and how easily you can get the medication into the dog. For example, dogs who resist pills may do better with drops added to food.

The Different Types of Antibiotics for Dogs: Pros and Cons Compared
