How long pets can remain at home alone depends on the pet, its age and its overall health. For example, an aquarium full of fish may be able to thrive for a week with the assistance of an automatic feeder. Dogs, however, will need daily bathroom breaks and feedings, says the Animal Humane Society. Adult dogs may be able to "hold it" for 10 to 12 hours, but young puppies and elderly dogs likely need more frequent breaks outside.

Pet sitters can address pets' needs while their owners are away. But finding one that will care for a pet like he or she is a member of the family can take some time and effort. Hill's Pet Nutrition suggests beginning the process of finding a pet sitter by making a list of needs. Considerations to include are whether the pet sitter should be in one's home or if the pet is to be brought to a pet care facility or a private sitter's residence. The pet may have particular health care requirements that also need to be addressed, such as a dog who requires insulin shots for diabetes.

While friends and family may be the first choices as pet sitters, there are benefits to using professional pet sitters. A professional sitter is properly trained in the care of many different animals, according to Pet Sitters International. He or she may have a local business license and be insured and bonded. Professional sitters are likely to make the pet a priority more than hobbyists or well-meaning acquaintances because caring for pets is how they earn their livings.
