How Can I Help My Puppy?

We bought two puppies when they were six weeks old and they're about nine weeks old now, but yesterday one of them died, how can I help the one that is still alive, because I've heard dogs can go into depression.

I reccommend taking it to the vet and getting a health test done. Ask them if they can do blood tests to determine if there is anything wrong with your puppy. It could have been a contagious disease, so just take precaution.

My puppy Akira didn't die from a disease, she died from strangulation because our family friend wasn't watching them when we asked him too.
