I love how someone wrote that cats are "bold and fearless" and then a page later another person posts a GIF of a cat falling into water and almost having a heart attack. Never seen an animal so scared in my life. Yeah, they're real fearless animals, hahaa.
Dogs may submit to the humans but it is out of respect, not fear that they stick their tails in. They respect those who look-out for them and have the pack mentality to keep peace with the leader when he/she is serious about something .They realize when they deserve punishment and learn from mistakes. It's not about fear. Try yelling at someone elses dog and see how the dog responds.
