First let me commend you on the patience and attitude that Taz is showing. He's being good, wants to play, but not pushy. I do think Jingle is showing her female bitch attitude, which is not all that unusual. You will hear time and time again "bitches rule." That pretty much says it. The one thing I don't see is that Jingle is showing any aggression. It's more like feeling things out, but I would stay alert. I do feel that all will be well, but Jingle and Belle have not been in the 3 dog situation, nor has Taz, and they all need adjusting time. Personally, I think things are going quite well so far.
Glad the baths went well, but sure they were glad when it was over.
As for Jingles teeth. Doesn't sound like the tooth brush is going to do all that much at this point; however, I'm not one to put a dog under just to have the teeth clean. There is always a risk. I would first suggest giving her, them, some raw meaty bones to chew on. They do quite well on tarter. I give mine about 1 every week or so, and so far so good. Baron is 6, Kaya soon 11 and Shrek 9 and haven't had the teeth cleaned yet. They have a little tarter in back, but nothing bad.
Thanks again and keep the updates coming.
Nancy, Baron,
