There are varieties of methods to conduct dog training. In fact, there are as many dog-training methods as there are dog trainers. Each will not agree on training approaches and specifics. Include the D I Y training that many dog owners do and the methods are multiplied. All dog-training methods, no matter the techniques used fall basically into two categories, the positive reinforcement, and the negative reinforcement. Release the dog from the leash and let him walk alone in the yard. Sometimes without our knowing it, dogs may not necessarily be ill but just the same, the dog is not feeling very well. When released from the leash and let to roam the yard the dog will look for particular herbs and plants to chew. This is his way to heal himself or at least to revitalize whatever lethargy that the dog is suffering from. When there is no place to sit, just stop walking. The dog will try to tug, get his attention and give the dog a treat or verbal assurances and resume walking. If you have a particularly energetic pup like a boxer or a retriever, you may want to tire the pup first before introducing him outside. Highly energetic games, for example a game of fetch, would be good to release extra energy, just do not play tug of war with the pup. Still, a clean bill of health should be the first thing you should look for in a potential would-be puppy. Some telltale clues that the puppy has or does not have any physical problems are: Nose and eyes - These should be clean and clear of any debris that is associated with sickness such as mucus. These should also look healthy. In areas where there are very cold seasons, a door should be opted instead of the usual open hole. Determining the Size Determining doghouse sizes are personal choices. You could build the doghouse as big as you want. However, you cannot build a doghouse smaller than this: Height: to determine a comfortable height that is also enough to insure good air circulation, add 9 inches to the height of a fully-grown dog of the same breed. They love interacting and playing with the whole family and are protective with children. Another endearing quality of the sporting dog is being affectionate and gentle. Herding Dogs Are also known as pastoral or working dogs. These dog breed are trained to work with other animals. Some herding dogs work well with most animals while other breeds are trained over generations to work with specific groups of animals making them adapted to specific animal traits enhancing their ability to the animal group that they are working on.
