Peace of mind
Being able to screen and meet the new owners can go a long way in giving someone peace of mind that they made the right choice for their pup. Imagine having to rehome your own pets, wouldn’t you feel better if you got to meet the new owners so you knew they went to a good home?
Owners know their dog best
As the owner, they know the dog better than anyone. They are the ones best able to give insight into how the dog behaves in the home, with other dogs, provide all the medical background, etc. They can also answer all the questions a new family may have that a rescue would not know.
Moving from home to home is difficult for any animal. A new home means a new environment, new people, new rules, a new routine, etc. Transition is never easy and going from one home straight to their forever home reduces the number of moves the dog must go through, thus reducing the potential for behavioral issues that could develop due to transitions.
Medical/ behavioral concerns
Many dogs that are needing to find a new home are in that situation because they have medical or behavioral needs the current owner is not able to meet. Unfortunately, rescues may not be able to meet these either. For example, if a dog needs to be an only dog or has resource issues, many rescues simply do not have that possibility because all their fosters have other animals in the home. Perhaps they have costly medical needs that the rescue cannot afford (most rescues are non-profit and operate on a very tight budget).
Not all rescues are created equal
Everyone may think all rescues are great and better suited to find a dog a new home, but you should also know that not all rescues are created equal. Many rescues have a shelter location or use boarding to house their dogs until they are adopted. This is not an ideal situation and may cause the dog to develop new behavior issues, making them harder to adopt out. Some rescues adopt out on a first come, first serve basis with little to no screening of the families. Some are so strict in their requirements that they have dogs in their care for months, or even years, because they place so many restrictions on who can adopt. They all have justifiable reasons for these restrictions, but it can greatly reduce their potential adopter pool.
