So for this article, it was because I have been wondering for a long time whether or not my dog understands what I say to him. I actually learned that dogs have a mental capacity of a 3 year old kid. Which means that they can understand what you tell them and in a small way, they can relate stuff that you say like when you give it a ball and keep saying ball, eventually, they'll understand what ball. Of course this would take patience and would depend on the type of obedience your dog has.
Can you find my doggie?
The article goes on to say that there was this dog named Rico who had a huge vocabulary and they tested it by putting objects in a separate room and then telling it what to get. Rico would bring back the correct object more than half of the time. They also tried putting something new wasn't in his vocabulary and he would get the right object 70% of the time. This just proves that dogs have some sort of mental capacity to do elimination.
Well? *taps paw*
It also mentions that dogs can sense your mood via the tone of your voice. Which explains why they sometimes will be extra cuddly when you're in a bad mood or will suddenly become excited when you sound excited. I love dogs!
