There are 74 million dogs and 88 million cats in homes nationwide, and pet owners can't watch all of them all day, every day.
Professional pet care services are available to help but, warns The Early Show's resident veterinarian, Dr. Debbye Turner, some could hurt Fido or Fluffy instead.
Just 10 years ago, doggy daycare was unheard of. Now, there are more than 4,000 canine kindergartens around the country, a booming part of a $16 billion dollar pet services industry.
There's no federal oversight of pet boarding facilities or pet sitters, Turner points out, and animals are being mistreated by untrained caregivers and sometimes other pets. Injuries and even deaths occur.
As Turner puts it, you wouldn't leave your child with just anybody, and you shouldn't leave your pet in the care of a kennel or pet sitter without first doing some homework.
Because of the lack of regulation by Washington, Turner says, there's no way of knowing the total number of deaths and injuries incurred at animal day care centers, kennels, or under the watch of sitters.
But incident reports Turner found from across the country are enough to make any pet owner wary.
Dog lover Charlie Ann Syprett, of Sarasota, Fla., told Turner, "There is such a need for quality, safe, reputable, reliable pet care."
She says one of her dogs suffered a severe eye injury in a kennel, so the next time she needed pet care, she used a pet sitter who, it turned out, "not only failed to take him out on a leash, but he failed to ensure that the gates were closed." Her dog was hit by a car and killed.
Stories like those are popping up nationwide, Turner observes.
Reporter Rick Sallinger of CBS station KCNC in Denver investigated the death of Fred Schubert's dog.
He was "all we had," Schubert told Sallinger.
The Alpine Dog House, where the dog was being watched, broke the news of his death with a phone message.
Sallinger's investigation found that the Colorado Sate Agriculture Department reports as many as 10 deaths and injuries to dogs at daycare and boarding facilities since 1995.
Colorado law mandates one human supervisor for every 15 dogs, but when KCNC took its probe undercover, it found the only one watching the dogs were its cameras.
The Better Business Bureau reports that complaints about pet boarding and pet sitting have more than doubled in the last five years.
So, how can people find reputable pet care facilities?
Ask friends, neighbors, veterinarians, local shelters, local trainers, and others for references, Turner urges. "They're gonna know when bad things have happened, and they'll be able to lead you in the right direction. Check those references!
