A new puppy, or an older dog that's been adopted, needs care and attention, especially when it is new to the home. Leaving a dog in alone unfamiliar surroundings for hours at a time is cruel and will cause problems for you and him. You need to organise someone (not necessarily always the same person) to visit several times a day, to let him out, otherwise you're putting in "solitary". Dogs are pack animals and they crave companionship. All dogs need social contact and exercise.
If they are deprived of any of these, bad behavior will almost certainly occur - and it's not the fault of the dog. Boredom and separation anxiety will manifest itself in destructive behavior and soiling of the house. Just ask yourself, how long could you tolerate being alone, with no books, no TV, no personal contact and no room to move around? How many trips to the bathroom do you make in the course of a day? Putting the dog in a crate is only part of the solution.
This will prevent any destructive behavior such as chewing furniture or personal possesions but won't solve the puppy's psychological problems, or his need for toilet breaks. Getting your dog to think of the crate as his own safe home or "den" will relieve his anxiety but you must take care of his toilet needs. It's necessary to consider the breed characteristics. Some breeds are more dependent on human company than others and this can be a big influence on their reaction to prolonged separation. Similarly, the more active breeds will suffer far more from long periods of confinement.
Imagine a border collie, shut up for long periods with no mental stimulation and no exercise! In no time at all, you'll have a very neurotic dog indeed. So, if your dog has to be alone in the house for large parts of the day, as a minimum you need; 1) a place (probably a crate) where he can feel secure and comfortable with some toys and familiar objects; 2) some arrangement, possibly with a neighbor or friend who is familiar with the dog, for periodic breaks for toilet and a little exercise; 3) provision of drinking water, preferably just before the toilet break; and 4) some stimulation, such as a radio talk show or some music. Toys can be a great distraction and comfort for your dog. There is a huge choice of toys which can keep him amused and allow him to chew to his heart's content. Buy a good number of toys, which will allow you to rotate them.
Some toys allow small treats to be hidden in them, keeping him interested for longer. It is vital that your dog learns that chewing anything other than his food or his toys is a definite No. It is best to limit his chewing to those toys which are specifically designed to be safe. Any other approach can make the dog confused. If you give him an old sneaker to chew, you can't blame him if his next choice is one of your brand new business shoes.
Some trainers advise leaving one of your old garments in the crate with the dog. He may not be able to distinguish this from your best slacks. It may be better to leave a few garments near the crate but out of reach, so he can feel the comfort of your scent.
As he becomes less anxious, you can leave his crate open, so that he can move about and then gradually allow him access to more rooms. You need to organise the family's routine, to allow for someone give him some exercise and the chance to go to toilet, before you all leave home and even more so when you all return. Sharing these tasks among family members will make it much easier.
