ORLANDO, FLA. — The takeaway from the Global Pet Expo, at which 985 exhibitors of pet products were spread out over 13 football fields’ worth of real estate in the Orange County Convention Center here, is that Americans really love their dogs. And yet, perhaps as a result of so much love, those dogs are increasingly anxious, bored, overweight, messy and have terrible breath. They suffer from separation anxiety and they worry about thunderstorms, traffic noises, visitors and vacuum cleaners. Their joints ache, and they eat too fast; they chew the furniture and bedevil the neighbors with their barking. Also, drool happens.

But such a thicket of issues encourages ingenuity — as does, presumably, the promise of a huge payday. Last year, Americans spent $55.7 billion on their pets, according to the American Pet Products Association, the group that sponsored the three-day event that ended on Friday. And next year’s spending, it estimated, will rise to $58.5 billion.

There were more than 3,000 new products at the show, and while Pet Expo is theoretically a big tent that aims to address all appetites, this reporter noted only a smattering of booths devoted to the affairs of cats, reptiles, fish and small rodents. Really, dogs are more interesting than betas, if more problematic behavior-wise. And you can dress them, too.

On the way to the farthest, chilliest corner of the convention center — like so much of Orlando, the building was enthusiastically air-conditioned — where many of the new exhibitors were planted, there were fleece dog snoods (the Doggy Dickey, from American Dog Apparel, $25); hand-smocked dog dresses from Oscar Newman Pet Couture ($72 to $79); and natty raincoats with detachable awning-like hoods (starting at about $40) from Push Pushi, whose chief operating officer, Steffen Kuehr, has another company that makes protective gear like kneepads for the military.
