I think science debated the old "size of brain" argument long ago -- it's not the size of the brain it's how it is developed and used.
However -- altho I haven't actually taken part in this whole discussion it's caused me to do some thinking and I'm going thru some stuff with Kee Shu right now and I'm going to make reference here AND I'm going to start a new thread ... well, just cos it might help someone.
Kee is a peke of undetermined age. Both my regular and holistic vets think maybe 10 - 12 years old, but I've been told by a former owner she could be 16 (she was tossed around a neighborhood for years after one of the neighbors got her out of a HORRID situation in Chicago where she and a sibling were literally tied outside in Chicago 24/7 YEAR ROUND!! *sigh* One of the neighbors 'bought' them on a garage sale for $20 and they were passed from neighbor to neighbor just because everyone felt sorry for her and Mishu.
When we first got her we affectionately referred to her as "not the brightest light in the box" -- and given her background ... well, a dog doesn't learn any more than it's taught, right?? But she is a SWEET little girl -- particularly for a peke, and she's got an incredibly docile, laid-back, very biddable personality. She's GREAT at pet therapy.
But -- you'd think her brain was wrapped in cotton batting about 8" thick. But the more we got to know her, the more we've realized it's more than just "not bright".
Part of it is a defense mechanism -- if you don't act like you know much, no one expects much of you. You can stay in the background, you can sink into the woodwork and no one hits you, hurts you or bothers you. It insulates you.
But how much of this is practiced ... we weren't sure. Altho she's not at all interested in being close to ANY human. (I can hear her say it if she were human "Don't trust people -- they'll let you down eventually ... keep to yourself, and don't let them hurt you. Don't love them and you won't get hurt.")
However I began to worry because she IS obsessive. She has this complicated little air-licking thing she does -- not quite fly-catching but close. Stress exacerbates it!! **She'll crane her neck to the left, LOOK LOOK ... lick lick lick lick .... crane her head the other direction, look look ... lick lick lick lick ... ** -- repeat from ** for HOURS.
My holistic vet kinda specializes in seizure dogs (acupuncture works REAL well on seizures) -- and Kee is what Dr. D has called "pre-seizure=y". Like ... the slightest thing could put her over the edge.
Dr. D put her on one herbal (a Chinese herb) really soon after we got her and we saw it make a TREMENDOUS difference in the obsessive licking/head craning behavior AND I saw more clear thought from her -- far less of the "duh .... where AM I and what was I gonna do when I got here?".
Ok -- that's all I'm gonna say HERE about this.
But I'm going to just put this out there for anyone who might care.
There are times when a dog's history may simply have caused the brain to not think clearly. Not quite dementia ... but ... well, frankly, the Chinese word for it is "brain phlegm" -- brain fog is a pretty good word for it. And it may simply be medical -- NOT intelligence.
I don't think Kee is the brightest light nor has she ever been. But I don't think she's stupid. I think she's made a LOT of life choices to avoid problems because she's been abused and neglected. I think she's developed a life habit of not 'trusting' humans -- and she truly doesn't understand what it is to go to a human for 'comfort'. But it LOOKS like she's numb and dumb.
Lots of things can be done for that -- I can't undo Lord-knows how many years of neglect, nor can I force her to trust me. But I can love her and I can help her. And in turn she's awesome with the kids at Give Kids the World. She's AWESOME with ... BABIES!!! Go figure!!
Who on earth would ever think a peke would be ***AWESOME*** with babies?? patient. and she completely enjoys being petted -- even if it's a bit heavy-handed-kid-wise. They're MY size and that's "cool" she thinks!
