Karen,
Thank you for your response. About seven or so years ago, I hired an expert to come to my home for one visit. She told me to use a water spray and/or to throw a rattle, or something that makes a loud noise, on the floor. The noise maker doesn't work now, because I believe she doesn't hear it. The spray works somewhat, but, of course, AFTER she is already trying to bite. That seems more like a bandaide to me. I'd like to prevent the attempt to bite in the first place.
Nikki's and Jeti's bowls are at opposite ends of the kitchen. When I was able I sat between them when they ate. Nikki waited until Jeti and I walked away from Jeti's bowl, then she finished it. My son will not try anything that takes a lot of time. He is convinced that Nikki is viscious and needs to be put away. Another son once told me the same thing. When I asked my vet, she told me that Nikki is not viscious.
I have used the lead to keep Nikki in check when people come, that is, when I know they're coming. I can't very well control her when the home health aide, or nurse or physical therapist come and are working with me.
I guess it boils down to the fact that I must depend on my son for help in this and I don't believe he's in a mood to do that. Even to put her in a room with a gate at the door requires effort on someone's part. I used to do that too.
Thanks, again for your response. Mary
