Some of the questions we get from our Frederick County Maryland dog training clients:
Where will my dog live while at training camp?
What will my dog do each day?
- Individual training sessions between 9 and noon.
- Afternoon break and crate rest between noon and 2 pm
- Custom tailored fitness program including treadmill time or free range play with appropriate dog or dogs from 2 to 5 pm and additional leash work
- Dinner time at 6:30 pm
- Evening relaxation involving “quiet rest” with humans
- 10:30 pm: Last call for potty and good night!
Dog boot camps helps facilitate training because it allows the dog to be ‘immersed’ in the training process. Each dog is housed in a very controlled setting, where the routines of living have been designed to maximize our training efforts. From how the dog is housed (crated in our absence and overnight, on a leash when we are present) to how the dog is expected to behave in the presence of many other dogs and distractions in my personal home enhances the learning proces.
Our Boarding and Training program helps create a more cooperative dog so the transition back to your home is considerably easier. Our job isn’t over, however. We continue to work with you to help maintain and improve the trainng that has already been started for you!
Dog Boot Camps cost more than private lessons because we are including your dog a a member of a household and are providing essential needs that include multiple daily walks just to potty (never less than 4 generally more like 8 to 10, depending on weather) and opportunities to interact with humans in a home setting. This is a critical distinction from trainng facilities that house dogs in kennels, where intimate interactions are far less frequent.
Lionheart K9 has provided video and written training support for all of our owners since the advent of the internet (yes, I am that old) and continue to do so with every dog. We routinely hear positive feedback from owners that prefer to watch our video taped sessions with them over our prepared instruction!
Will my dog listen to me when he comes home?
Do you use Positive Reinforcement?
We advocate for results-based dog training, in a timely manner and do not engage in the rhetoric of “positive”, “negative”, “punishment based” or “fear”. We are well-versed in the use of all contemporary training philosophies and tools and are able to create a unique experience for our training clients, one that helps them meet their goals and expectations.
The intelligent use of reinforcement to motivate willing cooperation creates thoughtful, well-trained problem solvers that are a pleasure to own. We create positive relationships where none existed and improve those relationships where conflict has taken the place of companionship.
What training tools do you use?
Will my dog always have to wear training gear?
Will my dog always have to wear equipment?
Do you offer any other training options?
Will my dog's personality change?
What can I expect my dog to know after training?
As with any learned task, what you don’t use, you lose, and it is the same with dogs. Your persistent practice of the things your dog has learned on a daily basis will help keep him trained.
What kind of training do you do?
Although the results may seem pretty similar, how one achieves that is always a unique path!
Where can I find your price list?
