Most people in my family owned dogs years ago, as in the 1950's and 1960'era onwards, and they were usually mongrels of all sorts. They were all pretty strong dogs, and never seemed to get ill,and I don't remember anyone of them ever going to visit a Vets.
They were all well loved by the families,and well trained, but nobody put dog clothes on them. They all just had warm places to sit and sleep. no fancy dog beds, and definitely no cages.
Tins of dog food were not widely available in the 1950 era, and dogs were given left over food, My late Mum and Grandmother, used to cook up some cheap meat and veg, like a version of a stew, to feed the dogs with, and they always had some Spillers shapes dog biscuits at hand.
I had to laugh the other day, there was a woman in the village here, she was walking along with a new dog, about two years old,,It was raining and a bit muddy underfoot, so she picked up the dog near a puddle,and carried it for some time, and said, come on charlie, let Mummy get you home quickly out of this nasty weather,we don't want you getting wet darling.
