Great idea, I get choked up thinking about past pets. They truly are a blessing.
Same here, man. And at the risk of sounding a bit fucked up, I honestly get more emotional thinking about my deceased dog than a lot of humans I know who've passed away in the last year. Only dogs are capable of truly unconditional love, we're too flawed for that. It's incredible to share and learn this just by gazing into your best friend's eyes.
I knew there'd be a day where my dogs would pass on and our would wreck me, but I didn't fathom never completely getting over them. Miss the fucker every day.
