Feeling blue

We had to put his ‘brother’ Leo, a terrier mix, a rescue, we’ve had for 4 years to sleep last week, he was 15 and it was time, now that we got his stuff back from the vet’s office, including the squishy pad he used to lay on, Ruger is laying on that pad and clearly feeling depressed and angsty since he now realizes Leo isn’t coming back from the vet. Poor guy, have to cheer him up some.
