Hello there, congratulations on your puppy
. From what I have learnt, a puppy with good temperament should be something in the middle of a pack meaning the puppy should possess a temperament that is in the middle out of all the puppies in the batch. The puppy shouldn't be overtly timid nor overtly brave. When you carry the puppy on its back, puppy should not be staring in to your eyes for very long and does not squirm hard for too long of a time. Also, some people used coins in cans to test the reactions of the puppies. The best reaction is when the puppy would be curious to see what is happening but is not too timid nor should it be charging. It is okay if they come check the can out out of curiosity. I hope this helps! The last time I looked for a puppy, mine was okay, just a little on the timid side but with a lot of socialization he turns out fine. I did have a lot of time back then to socialize him. My sister who wanted a playful naughty puppy got just what she wanted. She was the most hyper one in the batch and she charge at us (always the first) when we were there but she is happy with her dog because she likes a cheerful naughty little one.
