Dog before and after pictures

Most dog before and after pictures are of rescue dogs. These pictures are of dogs and with their puppy pictures photoshopped in.

Some dogs really do grow up to look like their baby pictures. Some are a lot cuter as adults. It is a beautiful idea having the pictures together in one print.
I wonder if it could be done for other types of pets.
