i often wonder if dogs are really colour blind?
When kingsley was at the shelter. He could never get along with any brown dogs and had to be separated from them - the shelter suspects that he was attacked by a GR or brown dog when he was younger.
Things got better after i adopted him and began to socialise him more.
However, he still can't stand Golden retrivers, GSDs and Huskies. Often, he'd notice them and want to attack them even before the other dogs got a chance to look at him and they are like at least 20 -30 feet away- so it's not the eye staring contest or anything like that.
On the other hand.. his best friend is a beagle. and ever since then.. he simply loves beagles.. often going up to them - strangers with tail wagging and such.
For most parts.. he is the aloof stay-away-from-me.. "i will ignore you if you don't come within inches from me" kind of dog.
