The last few days the weather has been a bit warmer

- in the upper 20s, after being below 0 for a number of days - and last weekend it was warm enough to melt our 8-9 inches of snow -- so I'm sure the ground feels warmer outside.
Roxy always loves the outdoors, but now she only wants to be outside by herself. She has barked in Bubba's face the last 2 days when he goes out with her. Today she even growled at him

-- Bubba is so mild manner, he just ignores her. But she wasn't happy. She leaves him alone after a few seconds, but you can just tell she wants him to go back inside, so she can have the yard to HERSELF!
Today it's going to get to 35 & it's sunny, she wants to be out there
I know she hates to have him out there if there are squirrels around -- Roxy is a true hunter, she watches, waits & only chases when she really thinks she can catch them

-- Bubba barks & chases the squirrels as soon as he sees them -- so I know that's at least one of her issues.
Does anyone else have a problem like this??? How do you handle it??
I don't want to her behavior getting worse - I do tell her to stop
