I took my chihuahua to Shadowhawk at West Wallsend for behavioural & obedience training when I was experiencing problems with her (not) responding to my commands and for incessant barking. The results were remarkable!
Shadowhawk Dog Training worked wonders. Carol Young, the owner and primary trainer is locally known as a 'dog whisperer' and can really get inside their heads! She has had extensive certification herself within the industry and has worked internationally.
I ended up leaving my dog with her for in-house training over about 10 days, which is one of a number of options available - depending on your (dogs) need, and your budget. It was very well worth it - although I did suffer some 'separation anxiety'.
Carol also provides private & group training and even does on-the-spot consultations. She works with you personally as well, and 'trains the trainer' to make sure you are able to maintain consistency for the long term, and she is always available for followup.
I really can't recommend Carol & Shadowhawk highly enough.
So my overall experience has been that the service is terrific and value for money worth every cent. Costs vary so it's best to make an appointment to discuss you and your dog's need in person with Carol.
