Being a Dog Groomer can be quite rewarding as you are in constant contact with the dog creating, therefore, a closer bond as you are handling and caring for the dogs best needs. You will be gratified by knowing the dog is clean and by decreasing its chances from various health problems such as thrush, scratches, infestation, parasites on the skin, and other skin problems, as well as a general health check making sure its free from any cuts, heat, swelling, lameness or temperament changes which, in turn, can be an indication of illness.
As mentioned above, puppies respond well to positive-reinforcement based training. It is important to acknowledge that dogs cannot possibly know which behaviours are right and which are wrong - it will be up to you to teach them. Take the time to show your puppy what you want them to do and reward them with a treat, praise, or a game each time they do the right thing.
