A cat's vision is not based on movement. At least not entirely. I'm not sure if rat-like yipping dogs are like that. In junior high and high school, one of my best friends had a very hyperactive Boston Terrier. We'll give my friend the fake name Bill. We'd hang out at Bill's house, we'd here his parents let the dog. "Bill's dog check!" someone would shout and we'd all freeze. Cause the dog would run in, sniff around, and pounce on whoever moved the move the most. If no one moved (rare) the dog might circle the room and then leave. It was funny that Bill's parent were very OCD about order and cleanliness. There house reminded us all of a line from Ferris Bueller's Day Off The place is like a museum. It's very beautiful and very cold, and you're not allowed to touch anything. But the dog was the least well-trained dog I knew and they were okay with the dog tearing stuff up figuratively or literally. I like dogs in general. I do not like Boston Terriers. I don't think it was just that Boston Terrier. The other few I have met have been spastic puppy tornados.
Neither was the T-Rex's. Jurassic Park got that wrong. The current idea is that the T-Rex had excellent binocular vision.
T-Rex "facts" seem to change pretty fast. If that is true that they had excellent binocular vision, that helps a lot with the "scavengers versus predators" debate. Binocular vision is probably better for predators. Then again, I guess vultures have keen eye sight. Enough of a tangent. Here are puppies doing puppy like things. At 1:27 there is a dog reacting to a life size dinosaur replica but the dog at 3:43 wins the Internet in my opinion though 4:50 has the worst case of broken legs (the cutesy soundtrack for that segment gave me a cavity). Actually the whole thing is full of gems.
It is fun to speculate what they are talking about. According to the people who posted this video, it's a father and daughter beagle duo. So many questions. Are they having a discussion? An argument? Or is he just teaching his daughter to bark properly? Is the big dog just saying "Get out of my bed!"? If daddy wasn't tethered would he walk away?
