How might the puppy’s new environment affect its growth and development?

New environments for puppies may make them excited, fearful, aggressive, or confused.

Explanation:

"When your dog first experiences a new location or environment, there's no way of knowing how they'll react. New sights, sounds, and smells could make them fearful, aggressive, or over-excited, but with the proper training and introduction, most dogs will quickly adapt and start taking every new location in stride." - Excerpt from *Puppy training textbook*

New environments are also a good thing in puppy growth, to teach them how to learn and adapt to new surroundings.

Hope this helps :)
