I feel for you all having to put down a companion. It's sad.
Let me try to brighten things with regards to dogs. Stupid Pea-Pie was sitting under the recliner yesterday when I got up. I felt a little bump when I closed the chair, but didn't consider it.
I went outside, messed around for a few, then went back in. "Honey, is the dog in there with you?" "No." CRAP!!!
She came out of there with her tail tucked and ears down not happy for hours.
The day we put her down is going to be a sad one for sure.
