They need to be crate-trained, housebroken, and obedience trained. They also need to be properly socialized by being inside with the family and handled frequently. This takes time and patience. You must expect the puppy to have accidents in your home as it learns to control its bladder and gives a signal it needs to go outside. Puppies also require a monthly regimen of shots until they are 6 months old.
Puppies cry, bark, vomit and chew.
They can invade gardens and decapitate flowers and dig up young plants. If adopting a puppy, you must expect to face these kinds of problems, and be prepared to deal with them effectively and without abusing or mistreating the dog. Most dogs are surrendered because of inadequate training on the part of the owner. Some people get a dog and expect it to be a perfect pet, and they become disgruntled when the dog behaves in a way that does not suit them. These dogs end up in shelters through no fault of their own.
