Local Medical Issues

There are numerous local medical issues that can impact your pet's health and which require your attention year-round. For example, there's heartworm disease. Heartworm can affect both cats and dogs and is transmitted by mosquitoes, which thrive in our region. It's a serious cause for concern. And since our winter temperatures are not cold enough to kill mosquito eggs, it's a year-round risk.

Likewise for the potential for flea and tick infestation, or intestinal parasites, each of which can pose problems in any season.

And finally, contrary to what you'd expect, allergies are a year-round issue. Many pets suffer from skin and ear allergies, the signs of which include scratching, redness in the ears and scaly skin.
