Thank you all, this makes me feel a little better. Of all the puppies I've had or interacted with in my family, I have never seen one quite like Tess, she is terrible with those teeth and they are like razor blades. If I try to take off her color or attach her leash, she tries to bite me, everything is such a battle with her but knowing that it will pass, is a relief. The name land shark suites her very well, my husband calls her little devil dog. It's so hard to get upset with her, even when it hurts so badly, because she's so darn cute and does the cutest things. I will miss her puppy cuteness but cannot wait for her to grow out of the land shark phase.
The more I read on this forum, the more I see that a lot of others are going through the same thing and that too makes me feel better, although I do feel for the arms and legs of those that are going through it.
