Not all people who adopt a dog do so only to make them as a pet. There are owners who seek to put their dogs to use according to the dog's activity or training. Some are made into therapy dogs, others as guide dogs. If you are considering a dog for specific purposes, you are advised to pick ones that have undergone special training or, in general, have the traits suitable for the function. Only rescue groups keep tab of their dogs' sources, observe their temperament, and investigate into their dogs' history. The rest just give them temporary foster homes. Puppies are also not advisable for adoption because they are too young to show their true temperament, behaviors, and features. You also can't approximate how much training, grooming, and medical attention the dog will likely need. If the pup insists on going to places where you do not want him to (like digging on a flowerbed for example) and you are tempted to tug at the leash, carry the pup instead, then move to another location. You could already take a more firm control when the pup appears to be comfortable being restrained. For people who can t commit to a lifelong responsibility, a senior dog offers a very ideal pet. Because they have shorter remaining lifespan, their owners don t have to have to turn their old dog away. Finally, adopting a senior dog is a selfless act of love. All dogs deserve a loving home, but senior dogs are especially entitled to one that is fit for retirement. Mid-size dogs, on the other hand, are ideal for most kinds of keepers from children, adult to old people. As middle range dogs, they tend to get along with all sorts of training, environment, and people. Although, these benefits do not apply to all mid-sized dogs. Giant dogs, big as they are, are perfect for people who have the space, budget, and patience for big animals. Temperament If you are the kind of person who likes peace and quiet around the house, find dogs that are peaceful and quiet by nature. Likewise, if you are the type that loves the outdoors and is athletic, find a dog that has the stamina to keep up and do not get easily distracted. Active and athletic dog types would need their daily requirement of hard running and long walks.
