Just like humans, pets can develop fungal infections. Dogs and cats can get yeast infections of the ears, suffer fungal growth around the nails, and are susceptible to skin fungus including the dreaded ringworm infestation that can easily be transmitted to humans. Fish are also prone to developing fungal infections on their fins. No one likes to think about these microscopic pests making their pets uncomfortable, but effective treatments are available. Finding the antifungal medication that works best for your pet’s fungal infection typically requires the diagnosis of a veterinarian. But once you know what medication will tackle the problem, you and your best friend can get back to normal.
