Aggresive as they get older?

[critter crazy]

Personally I would keep young dogs away from seniors, they just dont tolerate the young ones very well. Also most times, senior dogs will get aggressive due to pain. I know every senoir dog i have ever owned, usually became aggressive due to pain. Most was caused by arthritis.

Autumn certainly fits the bill. I wouldn't call it aggressive since she just growls or barksto tell them to go away. That's acceptable dog-talk to me. She's got arthritis. She doesn't like puppies jumping on her. She never liked puppy teeth though.
