If it is a small dog, he should be familiarized to his environment.

You should let him stay in a small room, for example the kitchen.

Experts recommend us to spend a few hours a day with or dog and to introduce him to as many friends and neighbors as we can until he turns 7-12 weeks old, because at this age the puppy holds the capacity to understand some situations.
If you have an adult dog, that needs to be fed only once a day, it is simpler. The dog will eat at night or in the evening when you get home. You will walk him in the morning and when you get back from work. But try not to be out of the house more that 8 hours because he has a schedule, he knows exactly when he is given food and when he will be walked. If you don’t impose him a rhythm, the dog will be stressed and the house a mess.
Never leave the dog alone when you are planning to go on a trip or on a vacation. If possible take him with you or if not, hire someone or ask some friends to take care of him.
