LOL, Gerties' like rolling her eyes thinking "The things I must put up with with this pup!" Esther looks a bit tense, head lowered, hovering on the toy, looking sideways, maybe sort of worried if she'll want it back, but a picture is just a frame in time. Good that you are monitoring, always keep an eye open. When one dog has a toy, the other will always want it (even if they have the exact same toys) and that alone can increase its value.
I guess Gertie needs to learn how to scratch an itch with a toy in her mouth!
