I am thinking of getting a dog. We are there all over the weekend though.
Dogs are highly social animals.
Dogs left alone for extended periods can experience a high degree of separation anxiety. However any intelligent dog can adapt to being left alone during the day. A very young puppy may need frequent walks throughout the day to relieve herself. A young puppy will need a walk during mid-day to relieve herself AND to be checked up on. Obviously she will need adequate water and food throughout the day, though her feedings as a young puppy may need to be carefully timed with her walks for obvious reasons.
