In the absence of obedience training, a dog who jumps, chews, barks and is generally dominant is simply being a dog, doing the things he would do to survive in the wild. In this case, be sure to get a few veterinary referrals and check out the facility. They should posses a Masters degree or higher or should at least be enrolled in such a program. When selecting a Behaviorist look into his or her educational qualifications as described above. Check whether they have a treatment facility, and always get a veterinarian's reference or two.
Behaviorists usually charge on an hourly basis unless an obedience program is indicated.
Rates are based on the type of program.
