Professional industry 
The professional pet-sitting industry is growing rapidly because many pet owners feel that there are advantages to using pet sitters, rather than traditional pet care options. Reasons people use pet sitters include:
- Possible reduced stress on pets because pets are cared for in their own homes
- No "travel trauma" to pets because they do not need to be transported anywhere
- Exposure to illnesses and parasites of other animals is minimized
- Required vaccinations are often less restrictive than those necessary at a kennel
- Pets stay on their regular routines and do not need to adapt to a new environment
- Not having to deal with neighbors, friends or family members feeling that they are inconvenienced
Professional pet sitters are often licensed, and insured for liability including care, custody, and control of the pets in their care. Many pet sitters are also bonded or insured for theft. Pet sitters usually have training, such as pet first aid certification, animal husbandry classes, or pet sitting accreditation. A number of professional organizations exist to help pet sitters improve their services.
In many areas, no special occupational license is required for pet sitters. The term "licensed" is often used by pet sitting professionals to refer to licenses to do business, kennel licenses, and/or animal transportation permits available within the coverage area of the business. These licenses may or may not be required, depending on the location. Licenses are not available in all areas.
There are many different services which can be offered by pet sitters.
Vacation care 
During vacation pet sitting, a pet sitter visits a client's home several times, as required. The exact length of visit is determined by both pet owners and pet sitters, averaging from fifteen to forty-five minutes. Typical services offered include: providing the pets' customary diet and exercise routine, administration of medications, vitamins, and other special care, monitoring health and arranging for medical treatment in case of illness. Most pet sitters bill clients on a per-visit or per-day basis, including additional charges for multiple pets, travel expenses, and special tasks. Less commonly, pet sitters offer live-in care. Pet sitters also provide house sitting in conjunction with vacation pet care.
Dog walking 
Pet sitters also provide dog walking services. Disabled clients and the elderly often hire pet sitters to exercise and care for their pets if they are unable to do so.
Pet sitters may also offer other more aggressive methods of exercise for dogs during dog walking appointments. These may include jogging, running, inline skating, bicycling, or dog scootering with client dogs.
Dog Boarding 
Pet sitters may also offer Home Dog Boarding. Much like traditional house sitting - this involves the dog boarding you the sitters own home environment. Allowing increased levels of exercise and play, confidence and social skills. Stress relief and alleviation of boredom. Constant supervision from a caring staff of one. Good behaviour and manners are promoted and rewarded and this provides peace of mind that your dog is safe and happy minus the guilty feeling about leaving your pooch home alone.
Insurance and bonding 
Most professional pet sitters are insured through nationwide Pet Sitter insurance providers.
As of 2010, the major American and Canadian pet sitting insurance providers include claim limits from 2 million to 4 million per claim for liability claims. They also include an uncommon endorsement that provides coverage for care, custody, and control of the client pets from $10,000 to $200,000 per occurrence. Coverage is included for fire damage, lost keys, and other negligence claims.
As of 2010, the major UK pet sitting insurance providers include similar claim coverages as the USA providers. The limits for liability claims generally range from £2,000,000 to £5,000,000.
Most pet sitter insurance plans provide coverage for pet transport. The majority of pet sitting industry insurers also provide care, custody, and control liability coverage for all animals, excluding loss from income from an animal that may be used for other business ventures such as farming.
Some resources recommend that pet sitters be bonded. That recommendation has been dismissed by many professional organizations in recent years.
A dishonesty or fidelity bond claim generally applies when a pet sitter is convicted in criminal court of theft from a client home. When the pet sitter is convicted, the bond will reimburse the client for the loss, and then seek reimbursement from the pet sitter. This process can take many years to complete, and usually relies on a criminal law court conviction.
Many pet sitters have decided to seek actual insurance coverage for theft instead of procuring a bond. Theft insurance coverage does not require convictions, and can include coverage for accidental breakage, mysterious disappearance, and accidental damage to items in a client home.
Other insurance topics 
Pet sitters are generally not protected from injury to themselves by regular pet sitting liability coverage. Pet sitter liability insurance usually covers injury to other people and other pets.
Certification and accreditation 
A variety of pet sitting organizations offer optional training, testing, or review of credentials for pet sitters in the form of certification or accreditation.
The curriculum of pet sitting programs may include pet care, health and first aid, nutrition and behavior, and/or business development and management.
Certification that is credentials based may require the pet sitter to provide a criminal background check, proof of insurance, proof of bonding, certificate of completion of a pet first aid program, documentation of business methods and policies, or other evidence to support their professionalism and adherence to minimum pet sitting industry standards.
It is more common for pet sitters to obtain separate certification specifically in pet first aid. Hands-on pet first aid and CPR training classes are offered through such well known organizations as the Red Cross, Petco, and PetTech. Virtual classes are also available for pet sitters who do not have hands-on classes available in their area.
