Dirty little secret is that a lot of college students abandon their pets when they graduate and move out.
That is the truth. Before we got married, my wife got an emaciated Doberman exactly that way. College kids moved out and vanished, unclipped and undocked Dobie was left in the yard to starve. Evil pricks could have dropped the dog at the shelter... but no. She got it and took care of it.
That dog loved her like no other till the day he died.
And all the ‘Rona people who decided they needed a dog during lockdown and abandoned them when they returned to work.
