That's a pretty narrow opinion Rob and I do agree a lot of people followed that practice and many still do or worse, they drop them off along side the road in the back country.Pet vets are having to look at animals as if they were semi-human, the owners expect long life for their pets and are willing to spend big.
50 years ago, if your dog was sick and dying it got 50 cents worth of lead. That is not how things are now.
I can only tell you what most of my friends and myself did when our pets were in dire straits. We took them to a VET.
People are different, some don't like their animals and barely tolerate them. Most like them and treat them well. A few are cruel and should be treated in the same manner they treat their animals.
When it's time for my pets to meet their end, I do it myself, out of respect/love for my pet. They don't like visiting the Vet and it stresses them out. At the final moment of their lives, which they are almost always fully aware of at the time, making it quick and painless as possible, without the drama and mental trauma is the best option.
Just like human Doctors, there are good ones, great ones, and abject failures. I knew of one who lost his license because he was a closet Sadist.
They're human. Some are greedy. Most work for a clinic, either by contract or salary, just like your Barber. That's why they come and go so often.
We take on the responsibility of taking care of these creatures. Failing them is failing yourself.
Sadly, far too many people have pets and they don't know how to take care of them or can't afford to take care of them.
Many shelters across Canada are full of 2-4 year-old pets whose owners got tired of them, couldn't take proper care of them when they returned to work or could no longer financially provide for them.
I like dogs, cats, and other animals. They give everything they have to offer and deserve something in return, even if it's only respect.
