IV treatments come in a variety of formulations. Your veterinarian can create a custom fluid treatment tailored to meet your dog or cat's exact needs. IV fluids aren't just water. These fluids contain varying levels of magnesium, potassium, dextrose, and more – delivering vitamins, minerals, and other vital nutrients to your pet right when they need them most. Dehydration, pain management, antibiotics treatment and more, can all be part of your loyal companion's IV treatment.
