Hii, dog trainer here! Fast / sudden movements are invitations of play within dog body language! And she Is infact seeking attention/engagement / being involved in the social moment that is occuring when she tries to steal seats or get in the middle of things (: dogs are social creatures! That’s how they became domesticated at all
@Parker 又 thank you. I wish she would calm down a bit though because he’s only 2. And he gets so mad when she won’t get out of his seat. My boyfriend said it’s like brother sister rivalry lol
The best thing I could really recommend for the seat thing would honestly be teaching your son how to give the get down command/cue!! It sounds silly, but if the novelty of this social interaction is that brother is new and she wants in on the lovins & happenings; hearing brother say “get doooooooooown” and then mom scattering treats on the floor; will be much more effective than ol mom saying “get off now” Yanno what I mean?
As for jumping into play situations the simplest answer would be physical management! When you know you’ll be running & playin with your son, put a barrier between you guys and the dog! Gates, crates, doors, walls, etc all of em work!
And for addressing the like delaying outside refusing to come in, AND the general zest for life; try to allot for some time to play outside one on one with the dog! Whatever that might look like! One of my dogs loves playing “I’m gonna getcha” he holds a toy and I just run after him, he doesn’t even want me to take the toy LOL the other one loves tug, my moms dog loves playing fetch, it really looks different for every dog, but it makes a huge impact & it can be for just 4-7 minutes it still counts
What do you mean "can't leave her out all night"?
Most likely a jealous thing … maybe getting her own toys to help with may help like licking mats, kong and etc. Definitely asking a trainer for insight too
