Puppy breath

It's been several weeks since my dear doggie passed away. He was my companion, my friend and occasionally the biggest pain in my ass. I loved him dearly. I've spent the last few days trolling the internet in search of puppies and breeders and rescue homes and such. But each picture has caused conflicted feelings. Can you replace a beloved pet so quickly? Is it really replacing, or just moving on? Can another dog fill the space left by Ralphie? I just dunno. But seriously, this face is killing me. Squee! Smoosh! Fuzzy! Soft! Heart!
