Possibly, but not necessarily. They can be the result of reaction to the animal's venom. If the blisters contain clear liquid, it's likely to be allergic or venom reactions; if it's cloudy or murky, consider infection (which would need to be treated as an infection). If these blisters go away in a day or so, you should be fine. If they get bigger, painful, hot, generate dark lines radiating outward, or pop and leave behind ulcers (craters), they'll need to be looked at.
