Gotta watch out for those crazy Toy Poodles. She is very very very submissive and scared of everything. It is apparently a submissive thing to show only the front teeth She does this while showing other very submissive behaviors so I know that is the way it goes. She is an older poodle I have had since 2005. She was a middle aged adult already, so who knows what happened the first years? She just went on heart medication a couple weeks ago as her heart murmur has gotten significantly worse since her last check up. She is goofy.
