Dog Killer Coworker

I am mad at a coworker right now. Her dog has been having a hard time getting around for a week (150 lbs) but she said when she gives her the meds the vet gave her, the dog acts like a puppy but is just having some mobility issues. But instead of pursuing help, she's going to put the dog down today. I get the dog is having issues, but if she’s acting like a puppy, maybe give her more time to heal? See if mobility improves? Talk to vet about other options? Seems like things got hard so you decided to go for the easy option. Bitch.
