I don't mean to dismiss the issue of suicide. However, if it's a larger issue in the industry, it doesn't really tell me about the experience of going to these particular practices and suggests that it's not Banfield (or Mars, Inc) in particular that is the problem. As a former psych stats researcher (well, undergrad/grad assisting my advisor once upon a time), I suspect there's a third cause (or multiple third causes) related to this unfortunate high correlation.

(Side note: give me a moment, I'm working on the puppy pics)

Edit:

This Time article does a bit of clarifying:

Dr. Will McCauley had just finished his shift at a small Dallas animal clinic when he went home, fed his pet pot-bellied pig and then held a loaded handgun to his head.
The 33-year-old veterinarian was wracked with student debt and worn down by the daily demands at work, which included euthanizing dogs and cats and being vilified by pet owners for not meeting their expectations. “I was tired in this miserable state of mind,” he says. “It just drained me so much.” For reasons he attributes to either fear or hope, McCauley didn’t kill himself that summer day in 2016, and he quit his job later that week and stopped practicing.
“I knew I had to make a change,” McCauley says. “I was dead on the inside.”

I work in a field (libraries) that isn't as stressful, but still deals with the general public that treats my co-workers and I like shit very often and we often enough get thrown under the bus by management, who've typically risen to their position by proving how much of a dedicated people-pleaser they are.

I'm not trying to claim it's on par, but my experience with demanding and entitled people makes it easy to imagine how some (too many) pet owners can be. I've had animals put down before. I've done nothing but thank the vets/technicians for their help. I don't know what makes some people so evil in these situations.
