Mom is spoiling the dog.
We have 5 dogs in our household, including Mom's little Maltese. Mom is understandably attached to her, but it goes way beyond that and Mom treats Mitzi like she is her little doll or baby. She continually feeds Mitzi from her her table, and I have been asking/telling Mom not to do that for the last 6 years or so. Even though Mom has mild dementia, she KNOES I don't like it when she does this, because when she doesn't know I'm there, she looks around to see if I am watching, then gives Mitzi food (usually from her fork). This has caused Mitzi to be overly territorial toward our other dogs when they so much as pass by on their way to get water, etc. I am beyond angry. I have lost any semblance of patience. I have tried explaining to Mom why it's a bad idea to feed Mitzi from her table. It is making Mitzi a spoiled little dog who attempts to rule the roost. Please advise.
