They seem to move in sync at times as if their bond is unconsciously guiding their actions. In that way, they remind me of our first pair of dogs, littermates who we adopted together. Those two dogs, Astro and Rover, seemed to communicate telepathically. We don't have many photos of them because Rover died so young. Moreover, we were too inexperienced as dog owners to know how fleeting a dog's life is and to take tons of photos! In the right sidebar, you can see one photo of them under an apple tree that was blossoming.
R and Shyla are our first pair who are not littermates but who seem to have a similar affinity for each other as littermates. They love to share sun puddles in the winter.
I love how Shyla snuggles with R's paw.
They can be difficult to photograph together because they both intensely scan the world around them while I'm clicking the shutter. They also react to every nuance of each others behavior. Consequently, it's rare to get them both looking in my general direction with their eyes open!
For that reason, I sometimes separate them for photos. That helps the single dog to focus on me rather than his sibling!
