10 common pet health problems -- and how much they cost

When it comes to the health and well-being of their animal friends, consumers are willing to dig deeper than ever into their bank accounts.

According to the American Pet Products Association, spending on veterinary care is expected to hit $16 billion this year, a year-over-year increase of about 3.2 percent. Medical supplies and over-the-counter medicines, which pet owners purchase at veterinarian offices, is expected to rise 5 percent to $15 billion in 2016.

One reason for the increased spending is that advances in human medicine have migrated to the animal world, according to PetPlan pet insurance.

"From cyberknife therapy for cancer treatment and hydrotherapy after a [knew] injury to acupuncture to treat allergies, many of the same treatments for people are also now available for our pets," wrote Elyse Donnarumma, Petplan veterinary manager, in an email. "But these treatments come at a cost. At Petplan pet insurance, we see an increase year-over-year for the amount we cover for our policyholders who are taking advantage of these treatments to help keep their pets healthy (and happy!)."
