It’s difficult to pinpoint why some dogs do better than others and if viewing the body has anything to do with that. However, it’s unlikely that seeing his old friend would do him any harm, so, ultimately, the choice is up to you. Often times, the grief or depression that a dog exhibits after the death of another dog stems from an evident change in “pack order. " This can then lead to a lost sense of security or routine.
Thus, hard as it is when one of the dogs has gone, stick to your usual habits: feed him at the same time as usual, take him for walks, and visit places you normally go. This reassures the dog that life goes on, which in turn helps him to cope.
A much better option is to act normally around food and feeding time, thus reinforcing the impression that although the other dog has gone, all is still right with his world. Thus, put the food down as usual, and if the dog doesn’t eat, after ten minutes throw the food away and don’t offer anything else until the next mealtime. This sounds harsh, but in dog language it is enforcing a sense of routine and security, which is what he needs during this time.
If the deceased dog was the leader, the survivor may feel insecure since his understanding of who is in charge has changed. This can show itself as barking excessively at other dogs, either to assert his new found freedom, or more likely because he feels threatened and barks to warn other dogs off. If the deceased was the subordinate dog, the surviving pack leader may experience a loss of purpose, in that his guidance and support is no longer needed. He may seem restless and aimless as he patrols around, without a pack member to follow his lead.
This excellent one-on-one interaction will divert his attention and strengthen the bond between you. It may even help alleviate your grief, too.
There is also a possibility of making the situation worse by stressing the survivor with a strange dog intruding on his territory. Only get another dog if you’re confident the two of you are ready.
If you’re dead set on another dog and your current one doesn’t take to your friend’s, consider another of a different sex or size. Your dog may be likely to take to a dog that’s less (or more) intimidating or one of another disposition.

This is marketed as Adaptil, and is available as a plug-in diffuser that infuses the pheromone into the air, or on a collar worn close to the dog’s skin. Adaptil contains a synthetic analogue of the chemical messenger (pheromone) given off by a nursing doggy mom that makes her pups feel safe and content. The dog breathes the pheromone in and it activates feelings of safety and wellbeing. While this is not a quick fix, it can help to decrease anxiety levels in a stressed dog, which can help him turn a new corner and become more well-adjusted.
The dose is 1-2mg/kg twice a day by mouth. Thus a 30kg Labrador requires half an 80mg tablet, twice a day. This drug does have side effects such as a dry mouth and constipation, and can increase the plasma levels of certain anti-epileptic drugs and so should be used with caution in these cases.
