Long-term treatment shouldn't force a choice between your animal's health and your budget. This section looks at the cost side of medication care the way a pharmacist would — comparing FDA-approved generics to brand-name equivalents, explaining how prescription transfers and refill scheduling work, and breaking down what chronic conditions like heartworm prevention, arthritis, allergies, or thyroid disease actually cost to manage over a year. Whether you're caring for one dog, a barn full of horses, or a herd, the goal is the same: keep the treatment plan affordable enough that your animal stays on it.
