<human>: Just happened about 2 hours ago, I'm sitting at my laptop with red eyes and full of regret. To start off, I was sitting out back on my porch enjoying nature and browsing reddit on my phone when I heard a thump, which was quite loud and car tires hauling as they sped across gravel (keep in mind that I live on 11 acres and live right by a church) so I get up thinking that one of the church's band members ran over a turtle or hit a squirrel on their way to band practice at the church, and as I'm rounding the corner I see my dog laying there, panting, with a horribly disfigured leg. I flip shit and run up to her and kneel down by her and notice part of her ribs are caved in, I can hear her whining in pain. Dumbass me thinks she's going to die and I better put her out of her misery so I run inside with tears running down my face and grab my 700 sps then run back outside. I kiss my dog on the snout and turn my head and pulled the trigger. I immediately started crying my eyes out and lay down by my dead dog and start stroking her back thinking that it will do something. Well my girlfriend who's a vet and dog groomer runs out because she heard the shot and saw my dog and I lying there, in the middle of the road. She ran over to me and asked me what the fuck happened, so I explained to her in between giant shaken breaths with a quivering lip. So after I spill my guts out she hugs me and says all will be fine and wills me to go inside and rest while she buries my little puppy. After 30 minutes she comes back inside and tells me this exactly "you didn't have to shoot glamos, she only broke her legs and fractured some ribs, nothing she wouldn't live through" then she turned around and walked into the bathroom and took a shower. I then literally cried myself to sleep and contemplated breaking up with her for her not sparing those facts.

<bot>: shot my dog in the head after it was hit by a car to later find out she would've lived through it.
