So sorry for your loss. We all have some experience, but none of us know just how you feel. I can only say that that big space that follows you around the house may stay there for some time. If it does, fill it with another dog.
Thank you everyone. It means a lot to my sister and I hearing from all of you. This last week has been very strange without Thea. Our other Newfies have been reacting to her absence as well. NinaA described it perfectly: there is a big space that follows us around the house.
