If you think it's expensive to hire a professional dog trainer, wait until you hire an amateur!
WHAT TO LOOK FOR IN A POTENTIAL DOG TRAINER BEFORE YOU COMMIT TO A TRAINING PROGRAM
Working with a qualified professional can, in some cases, mean the difference between a harmonious life with your dog and having to give up a dog for re-homing or euthanasia. But the search process can be confusing. Dog training is a science, but the industry is (as yet) unregulated with no licensing requirements or regulatory oversight. This makes it difficult to know what to look for.
Assess the trainer
Browse the trainer’s website and any other marketing materials. Does everything look and sound professional? Do the messages appeal to you? If so, set up a phone call or in-person meeting. Can the trainer answer your questions about training, behavior, and methods knowledgeably and clearly? Is the trainer patient and thorough with replies? Do you feel comfortable with the trainer's responses to your questions? Does the trainer have the experience, education, and working knowledge to help you with the problems you need help with? Can the trainer provide references from clients?
Beware of red flags
A couple of things should raise a red flag in your assessment. If the trainer focuses on a model of dominance and submission or uses primarily punishment-based methods.
