Many of you know that we are dealing with Betty, our dear Rottie's, cancer at the moment and was wondering if any of you think that dogs know when other dogs are ill? Sometimes it seems that my other rottie, Blitz, acts much more loving to Betty and a bit more careful around her so as not to "hurt Her". I also notice that our other dog, Bella, isn't roughhousing with her any more lately. They used to jump all over each other and Bella has backed off lately and licks her face more often than usual. Could just be me imagining things but would like to hear your thoughts and/or experiences.
