Sporkasia - I had a friend who lived in the country and his family had several dogs. The animals would run through fields and woods all day and come home with numerous ticks. Removing the ticks every evening was my friend's job. He had a special pair of tweezers he used to grasp the ticks, and that was the only tool required.
Mostly, I think that shows how much more we know today about taking care of pets, and people today are more on the ball when it comes to caring for their animals than people were 30 years ago. I'm not saying people cared less for their pets 20 and 30 years ago, but I do think pets were viewed differently back then.
The only time my friend's dogs got any medical care was when they got their rabies vaccinations. Today, dogs have routine checkups as often as people. Also, we know more about tick bite diseases now than we did years ago.
