Anyone else found that their pets are very protective of them and are really clingy? Both my dogs have been, especially the older one! At the beginning of my pregnancy, my younger dog would carry my bras around and take them out the washing basket! Now both of them sleep in my bed, my older German Shepard when I walk him, when I have the energy, anyone walks past me he comes right up beside me and growls at people walking past! Anyone else experienced anything like this?
