Staring At You
You might find it a bit odd that your dog is fixated on you most of the time, but to a dog, this is totally normal. Perhaps your dog is staring at you since they want a treat and know that nobody could possibly resist their sweet puppy dog eyes.
Shaking Toys
Your dog violently shaking their toys in their mouths back and forth might seem adorable and funny to you, but to them, they are replicating the way they would kill prey if they are in the wild. It is hard to imagine that your sweet pup can do such a thing, but this is sometimes second nature for them.
