worried about Runner

[luvofallhorses]

maybe she's having a bad week?

could be. Otherwise she acts fine and normal.

She may need NILIF. If she's up on the couch growling, command her to move to the floor.

Molly used to do it too - but then I started not allowing her up on furniture and it kicked the habit.

Is she in any pain at all and perhaps just not wanting anyone bothering her? Even if she isn't showing any other signs besides aggression, she could be. My dogs would never let us know when they were in pain. Either that, or she's just doesn't understand fully where she sits in pack order. NILIF works wonders so if you haven't started that, I suggest you do and if you are using it, then continue and maybe be a bit stricter. Also, when she's doing something wrong try not to just call out her name. It should be a command such as "enough".

she may be in pain. It's been a lot cooler lately. Does the cool wweather make them more sore?

My Gordon Setter x that had a bone chip in his shoulder would suffer a great deal of pain during winter and moist days, so it's very likely she could be feeling pain during these cold months.
